Astrophysicists on twitter an in depth analysis of tweeting and scientific publication behavior
arXiv: Digital Libraries, 2014Co-Authors: Stefanie Haustein, Timothy D. Bowman, Kim Holmberg, Isabella Peters, Vincent LarivièreAbstract:This paper analyzes the tweeting behavior of 37 Astrophysicists on Twitter and compares their tweeting behavior with their publication behavior and citation impact to show whether they tweet research-related topics or not. Astrophysicists on Twitter are selected to compare their tweets with their publications from Web of Science. Different user groups are identified based on tweeting and publication frequency. A moderate negative correlation (p=-0.390*) is found between the number of publications and tweets per day, while retweet and citation rates do not correlate. The similarity between tweets and abstracts is very low (cos=0.081). User groups show different tweeting behavior such as retweeting and including hashtags, usernames and URLs. The study is limited in terms of the small set of Astrophysicists. Results are not necessarily representative of the entire astrophysicist community on Twitter and they most certainly do not apply to scientists in general. Future research should apply the methods to a larger set of researchers and other scientific disciplines. To a certain extent, this study helps to understand how researchers use Twitter. The results hint at the fact that impact on Twitter can neither be equated with nor replace traditional research impact metrics. However, tweets and other so-called altmetrics might be able to reflect other impact of scientists such as public outreach and science communication. To the best of our knowledge, this is the first in-depth study comparing researchers' tweeting activity and behavior with scientific publication output in terms of quantity, content and impact.

Astrophysicists' conversational connections on Twitter.
PloS one, 2014Co-Authors: Kim Holmberg, Stefanie Haustein, Timothy D. Bowman, Isabella PetersAbstract:Because Twitter and other social media are increasingly used for analyses based on altmetrics, this research sought to understand what contexts, affordance use, and social activities influence the tweeting behavior of Astrophysicists. Thus, the presented study has been guided by three research questions that consider the influence of Astrophysicists’ activities (i.e., publishing and tweeting frequency) and of their tweet construction and affordance use (i.e. use of hashtags, language, and emotions) on the conversational connections they have on Twitter. We found that Astrophysicists communicate with a variety of user types (e.g. colleagues, science communicators, other researchers, and educators) and that in the ego networks of the Astrophysicists clear groups consisting of users with different professional roles can be distinguished. Interestingly, the analysis of noun phrases and hashtags showed that when the Astrophysicists address the different groups of very different professional composition they use very similar terminology, but that they do not talk to each other (i.e. mentioning other user names in tweets). The results also showed that in those areas of the ego networks that tweeted more the sentiment of the tweets tended to be closer to neutral, connecting frequent tweeting with information sharing activities rather than conversations or expressing opinions.

Astrophysicists on Twitter : An in-depth analysis of tweeting and scientific publication behavior
Aslib Journal of Information Management, 2014Co-Authors: Stefanie Haustein, Timothy D. Bowman, Kim Holmberg, Isabella Peters, Vincent LarivièreAbstract:Purpose – The purpose of this paper is to analyze the tweeting behavior of 37 Astrophysicists on Twitter and compares their tweeting behavior with their publication behavior and citation impact to show whether they tweet research-related topics or not. Design/methodology/approach – Astrophysicists on Twitter are selected to compare their tweets with their publications from Web of Science. Different user groups are identified based on tweeting and publication frequency. Findings – A moderate negative correlation (ρ=−0.339) is found between the number of publications and tweets per day, while retweet and citation rates do not correlate. The similarity between tweets and abstracts is very low (cos=0.081). User groups show different tweeting behavior such as retweeting and including hashtags, usernames and URLs.

astronomers Astrophysicists do not know how to properly apply gravitational collapse
viXra, 2019Co-Authors: Jeffrey Joseph WolynskiAbstract:A screenshot and some explanation is given to show why and how astronomers/Astrophysicists got it all wrong. This is to prove beyond a reasonable doubt with written documentation that astronomers/Astrophysicists have the tool called "gravitational collapse", but do not know how to properly use it. Some explanation is provided with examples.

Stellar Metamorphosis: The Life Hypothesis Versus the Habitable Zone Hypothesis
viXra, 2014Co-Authors: Jeffrey Joseph WolynskiAbstract:In the star sciences astronomers and Astrophysicists have ignored basic understanding of what life needs to survive as well as what is needed for water to exist in liquid form. The life hypothesis as covered in the General Theory of Stellar Metamorphosis is contrasted with the Habitable Zone Hypothesis of establishment scientism.

Astrophysicists do not Understand Communication
viXra, 2013Co-Authors: Jeffrey Joseph WolynskiAbstract:It has been assumed for some time that Earth was the center of the universe and that its study was completely independent of the stars. This faulty assumption has lead scientists to continually draw up confusing theories of stellar evolution that do not make any sense. As well their definitions are counter to consistency itself, thus are unscientific. We will see that the problems with astrophysics are rooted in language itself. Before humans had telescopes it was assumed that the Earth was the center of the universe. It was immovable, unchanging, solid structure that was different than the heavens above. This mentality is still harbored even in the 21 st century by confused Astrophysicists. We can see this confusion in their theories of star evolution that do not include objects that are mostly liquid and solid structure such as the Earth. The study of the Earth is kept as a mutually exclusive area of study called "geophysics" and "geology". These two fields of research go over the physics involved with the formation, structure and evolution of the Earth. The processes are both uniformitarian (mostly unchanging) and catastrophic
