You may have heard about a new study that challenges standard dark-matter cosmology. This thread by @8minutesold is a masterful piece of high-level outreach by one of the researchers behind that work. https://t.co/YSJxf3tley

What I *love* about this is that it’s good honest astronomical observations showing a potential crack in current paradigm, science in action!

The Finnish Astronomy Magazine “Tähdet ja avaruus” interviewed and even featured me with a photo in their print edition (see photo to the right).

Interviewed by Nature.com Blog Of Schemes and Memes:
On the topic of being a PhD student.
Press release by the University of Bonn: “Kosmische Geisterfahrer” (Cosmic Wrong-Way Driver)
Based on my paper “ Making Counter-Orbiting Tidal Debris: The Origin of the Milky Way Disc of Satellites“. The press release was covered by a number of German media, including the print and online version of the local newspaper General-Anzeiger Bonn.
Press release by the University of Bonn: “Local-Group-of-galaxies study raises severe doubts as to the existence of dark matter” (in German)
Based on the paper “Local-Group tests of dark-matter Concordance Cosmology: Towards a new paradigm for structure formation“. This press release generated a lot of attention (articles in the Berliner Zeitung, Frankfurter Rundschau, der Standard and others). In addition to numerous calls by newspaper journalists for background infos and soundbites, I was interviewed for two radio programs, once together with Pavel Kroupa (for “Forschung Aktuell” in the Deutschlandfunk) and once on my own (for “Logo – das Wissenschaftsmagazin” in NDR Info).
