  • prospects for improving cosmological parameter estimation with gravitational wave standard Sirens from taiji
    Chinese Science Bulletin, 2020
    Co-Authors: Ze-wei Zhao, Ling-feng Wang, Jing-fei Zhang, Xin Zhang
    Abstract:

    Abstract Taiji, a space-based gravitational-wave observatory, consists of three satellites forming an equilateral triangle with arm length of 3 × 10 6 km, orbiting around the Sun. Taiji is able to observe the gravitational-wave standard Siren events of massive black hole binary (MBHB) merger, which is helpful in probing the expansion of the universe. In this paper, we preliminarily forecast the capability of Taiji for improving cosmological parameter estimation with the gravitational-wave standard Siren data. We simulate five-year standard Siren data based on three fiducial cosmological models and three models of MBHB's formation and growth. It is found that the standard Siren data from Taiji can effectively break the cosmological parameter degeneracies generated by the cosmic microwave background (CMB) anisotropies data, especially for dynamical dark energy models. The constraints on cosmological parameters are significantly improved by the data combination CMB + Taiji, compared to the CMB data alone. Compared to the current optical cosmological observations, Taiji can still provide help in improving the cosmological parameter estimation to some extent. In addition, we consider an ideal scenario to investigate the potential of Taiji on constraining cosmological parameters. We conclude that the standard Sirens of MBHB from Taiji will become a powerful cosmological probe in the future.

  • forecast for cosmological parameter estimation with gravitational wave standard Siren observation from the cosmic explorer
    Journal of Cosmology and Astroparticle Physics, 2020
    Co-Authors: Shangjie Jin, Xin Zhang, J Zhang
    Abstract:

    The third-generation ground-based gravitational-wave (GW) detector, Cosmic Explorer (CE), is scheduled to start its observation in the 2030s. In this paper, we make a forecast for cosmological parameter estimation with gravitational-wave standard Siren observation from the CE. We use the simulated GW standard Siren data of CE to constrain the ΛCDM, wCDM and CPL models. We combine the simulated GW data with the current cosmological electromagnetic observations including the latest cosmic microwave background anisotropies data from Planck, the optical baryon acoustic oscillation measurements, and the type Ia supernovae observation (Pantheon compilation) to do the analysis. We find that the future standard Siren observation from CE will improve the cosmological parameter estimation to a great extent, since the future GW standard Siren data can well break the degeneracies generated by the optical observations between various cosmological parameters. We also find that the CE's constraining capability on the cosmological parameters is slightly better than that of the same-type GW detector, the Einstein Telescope. In addition, the synergy between the GW standard Siren observation from CE and the 21 cm emission observation from SKA is also discussed.

  • prospect for constraining holographic dark energy with gravitational wave standard Sirens from the einstein telescope
    European Physical Journal C, 2020
    Co-Authors: Jing-fei Zhang, Xin Zhang, Hongyan Dong
    Abstract:

    We study the holographic dark energy (HDE) model by using the future gravitational wave (GW) standard Siren data observed from the Einstein Telescope (ET) in this work. We simulate 1000 GW standard Siren data based on a 10-year observation of the ET to make this analysis. We find that all the cosmological parameters in the HDE model can be tremendously improved by including the GW standard Siren data in the cosmological fit. The GW data combined with the current cosmic microwave background anisotropies, baryon acoustic oscillations, and type Ia supernovae data will measure the cosmological parameters $$\Omega _{\mathrm{m}}$$, $$H_0$$, and c in the HDE model to be at the accuracies of 1.28%, 0.59%, and 3.69%, respectively. A comparison with the cosmological constant model and the constant-w dark energy model shows that, compared to the standard model, the parameter degeneracies will be broken more thoroughly in a dynamical dark energy model. We find that the GW data alone can provide a fairly good measurement for $$H_0$$, but for other cosmological parameters the GW data alone can only provide rather weak measurements. However, due to the fact that the parameter degeneracies can be broken by the GW data, the standard Sirens can play an essential role in improving the parameter estimation.

  • cosmological parameter estimation with future gravitational wave standard Siren observation from the einstein telescope
    Journal of Cosmology and Astroparticle Physics, 2019
    Co-Authors: Jing-fei Zhang, Shangjie Jin, Ming Zhang, Xin Zhang
    Abstract:

    In this work, we use the simulated gravitational wave (GW) standard Siren data from the future observation of the Einstein Telescope (ET) to constrain various dark energy cosmological models, including the ΛCDM, wCDM, CPL, αDE, GCG, and NGCG models. We also use the current mainstream cosmological electromagnetic observations, i.e., the cosmic microwave background anisotropies data, the baryon acoustic oscillations data, and the type Ia supernovae data, to constrain these models. We find that the GW standard Siren data could tremendously improve the constraints on the cosmological parameters for all these dark energy models. For all the cases, the GW standard Siren data can be used to break the parameter degeneracies generated by the current cosmological electromagnetic observational data. Therefore, it is expected that the future GW standard Siren observation from the ET would play a crucial role in the cosmological parameter estimation in the future. The conclusion of this work is quite solid because it is based on the analysis for various dark energy models.

  • a statistical standard Siren measurement of the hubble constant from the ligo virgo gravitational wave compact object merger gw190814 and dark energy survey galaxies
    The Astrophysical Journal, 2020
    Co-Authors: Antonella Palmese, J. Devicente, Maria E. S. Pereira, J. Annis, W. G. Hartley, K. Herner, Martin Crocce, Dragan Huterer, M Soaressantos, Magana I Hernandez
    Abstract:

    We present a measurement of the Hubble constant H-0 using the gravitational wave (GW) event GW190814, which resulted from the coalescence of a 23M(circle dot) black hole with a 2.6M(circle dot) compact object, as a standard Siren. No compelling electromagnetic counterpart has been identified for this event; thus our analysis accounts for thousands of potential host galaxies within a statistical framework. The redshift information is obtained from the photometric redshift (photo-z) catalog from the Dark Energy Survey. The luminosity distance is provided by the LIGO/Virgo gravitational wave sky map. Since this GW event has the second-smallest localization volume after GW170817, GW190814 is likely to provide the best constraint on cosmology from a single standard Siren without identifying an electromagnetic counterpart. Our analysis uses photo-z probability distribution functions and corrects for photoz biases. We also reanalyze the binary black hole GW170814 within this updated framework. We explore how our findings impact the H-0 constraints from GW170817, the only GW merger associated with a unique host galaxy. From a combination of GW190814, GW170814, and GW170817, our analysis yields H-0 = 72.0(-8.2)(+12) km s(-1) Mpc(-1) (68% highest-density interval, HDI) for a prior in H-0 uniform between [20and140] km s(-1)Mpc(-1). The addition of GW190814 and GW170814 to GW170817 improves the 68% HDI from GW170817 alone by similar to 18%, showing how well-localized mergers without counterparts can provide a significant contribution to standard Siren measurements, provided that a complete galaxy catalog is available at the location of the event.

    Abstract:

    We present a measurement of the Hubble constant $H_0$ using the gravitational wave (GW) event GW190814, which resulted from the coalescence of a 23 $M_\odot$ black hole with a 2.6 $M_\odot$ compact object, as a standard Siren. No compelling electromagnetic counterpart with associated host galaxy has been identified for this event, thus our analysis accounts for $\sim$ 2,700 potential host galaxies within a statistical framework. The redshift information is obtained from the photometric redshift (photo-$z$) catalog from the Dark Energy Survey. The luminosity distance is provided by the gravitational wave sky map published by the LIGO/Virgo Collaboration. Since this GW event has the second-smallest sky localization area after GW170817, GW190814 is likely to provide the best constraint on cosmology from a single standard Siren without identifying an electromagnetic counterpart. Our analysis uses photo-$z$ probability distribution functions and corrects for photo-$z$ biases. We also reanalyze the binary-black hole GW170814 within this updated framework. We explore how our findings impact the $H_0$ constraints from GW170817, the only GW merger associated with a unique host galaxy, and therefore the most powerful standard Siren to date. From a combination of GW190814, GW170814 and GW170817, our analysis yields $H_0 = 69.0^{+ 14}_{- 7.5 }~{\rm km~s^{-1}~Mpc^{-1}}$ (68% Highest Density Interval, HDI) for a prior in $H_0$ uniform between $[20,140]~{\rm km~s^{-1}~Mpc^{-1}}$. The addition of GW190814 and GW170814 to GW170817 improves the 68% HDI from GW170817 alone by $\sim 12\%$, showing how well-localized mergers without counterparts can provide a marginal contribution to standard Siren measurements, provided that a complete galaxy catalog is available at the location of the event.

  • a standard Siren measurement of the hubble constant from gw170817 without the electromagnetic counterpart
    The Astrophysical Journal, 2019
    Co-Authors: M Fishbach, Magana I Hernandez, R Gray, Arijit Sur, F Acernese, Lloyd Paul Aiello, A Allocca, M A Aloy, A Amato, S Antier
    Abstract:

    We perform a statistical standard Siren analysis of GW170817. Our analysis does not utilize knowledge of NGC 4993 as the unique host galaxy of the optical counterpart to GW170817. Instead, we consider each galaxy within the GW170817 localization region as a potential host; combining the redshifts from all of the galaxies with the distance estimate from GW170817 provides an estimate of the Hubble constant, H_0. Considering all galaxies brighter than 0.626L*_B as equally likely to host a binary neutron star merger, we find H_0 – 77^(+37)_(-18) km s^(−1) Mpc^(−1) (maximum a posteriori and 68.3% highest density posterior interval; assuming a flat H_0 prior in the range [10, 220] km s^(−1) Mpc^(−1)). We explore the dependence of our results on the thresholds by which galaxies are included in our sample, and we show that weighting the host galaxies by stellar mass or star formation rate provides entirely consistent results with potentially tighter constraints. By applying the method to simulated gravitational-wave events and a realistic galaxy catalog we show that, because of the small localization volume, this statistical standard Siren analysis of GW170817 provides an unusually informative (top 10%) constraint. Under optimistic assumptions for galaxy completeness and redshift uncertainty, we find that dark binary neutron star measurements of H_0 will converge as 40%/√(N), where N is the number of sources. While these statistical estimates are inferior to the value from the counterpart standard Siren measurement utilizing NGC 4993 as the unique host, H_0 = 76^(+19)_(-13) km s^(−1) Mpc^(−1) (determined from the same publicly available data), our analysis is a proof-of-principle demonstration of the statistical approach first proposed by Bernard Schutz over 30 yr ago.

  • forecasting the interaction in dark matter dark energy models with standard Sirens from the einstein telescope
    Journal of Cosmology and Astroparticle Physics, 2020
    Co-Authors: Riis R A Bachega, Andre A Costa, Elcio Abdalla, K S F Fornazier
    Abstract:

    Gravitational Waves (GW's) can determine the luminosity distance of the progenitor directly from the amplitude of the wave, without assuming any specific cosmological model. Thus, it can be considered as a standard Siren. The coalescence of binary neutron stars (BNS) or neutron star-black hole pair (NSBH) can generate GW's as well as the electromagnetic counterpart, which can be detected in a form of Gamma-Ray Bursts (GRB) and can be used to determine the redshift of the source. Consequently, such a standard Siren can be a very useful probe to constrain the cosmological parameters. In this work, we consider an interacting Dark Matter-Dark Energy (DM-DE) model. Assuming some fiducial values for the parameters of our model, we simulate the luminosity distance for a "realistic" and "optimistic" GW+GRB events , which can be detected by the third-generation GW detector Einstein Telescope (ET). Using these simulated events, we perform a Monte Carlo Markov Chain (MCMC) to constrain the DM-DE coupling constant and other model parameters in $1\sigma$ and $2\sigma$ confidence levels. We also investigate how GW's can improve the constraints obtained by current cosmological probes.

  • Radiocesium (137Cs) concentrations in the two-toed amphiuma (Amphiuma means) and the lesser Siren (Siren intermedia).
    Journal of environmental radioactivity, 2019
    Co-Authors: David L. Haskins, Albert L. Bryan
    Abstract:

    Abstract This study sought to determine radiocesium (137Cs) concentrations in two species of aquatic salamanders – the two-toed amphiuma (Amphiuma means) and the lesser Siren (Siren intermedia) on the Savannah River Site. Concentrations (137Cs Bq/g, dry wt) of the two species were similar at both 137Cs-contaminated (A. means = 0.733 ± 0.242, n = 5; S. intermedia = 0.839 ± 0.722, n = 5) and reference sites (A. means = 0.028 ± 0.020, n = 5; S. intermedia = 0.042 ± 0.027, n = 11). Salamanders captured in areas impacted by 137Cs contamination exhibited significantly higher 137Cs concentrations than individuals captured at reference sites (U = 146, p

  • mercury concentrations in the two toed amphiuma amphiuma means and the lesser Siren Siren intermedia validating non lethal sampling methods in southeastern aquatic salamanders
    Archives of Environmental Contamination and Toxicology, 2019
    Co-Authors: David L. Haskins, Alexis M. Korotasz, Albert L. Bryan
    Abstract:

    The global decline of amphibians is a major conservation issue. Many stressors are recognized for this decline including exposure to environmental contaminants. Mercury (Hg) is an environmental contaminant that bioaccumulates in wildlife and can cause a variety of negative impacts across taxa, including amphibians. Amphiuma and Siren spp. can comprise a large portion of biomass within their respective ecosystems, and thus, likely serve as important predators or prey in wetland communities. However, due to their cryptic nature, little is known about their ecology, diet, and accumulation potential. We sought to validate a nonlethal sampling method to quantify total mercury (THg) in two enigmatic species of aquatic salamanders: the two-toed amphiuma (Amphiuma means) and the lesser Siren (Siren intermedia). We examined relationships between THg content in lethal (whole-body) and nonlethal (tail clip) samples. Tail clips were statistically significant predictors of whole-body THg (all p < 0.001), explaining 84–89% of variation in whole-body THg. Average whole-body THg (mg/kg) did not significantly differ between the two species (p = 0.97), and overall, they had similar whole-body THg content (S. intermedia = 0.330 ± 0.04, n = 18; A. means = 0.333 ± 0.07, n = 11). To our knowledge, these data represent the first reported Hg burdens in A. means and S. intermedia.
