How the cosmic environment depletes galaxies of their gas

An international team of researchers, led by Jonathan Freundlich (University of Strasbourg, Astronomical Observatory), has revealed how a dense cosmic environment depletes galaxies of their gas. By mapping the molecular gas in a galaxy group located 7 billion light-years away, they found that the galaxies in this group harbor, on average, gas reservoirs reduced by more than half compared to similar isolated galaxies. The results of this study are published in the journal Astronomy & Astrophysics.
