Testing dark matter models and modified gravity theories with spatially resolved HI observations
Federico Lelli, Antonino Marasco, Timothy A. Davis +8
Understanding the nature of dark matter (DM) is one of the most pressing questions of modern physics. The flat rotation curves of galaxies, especially the extended HI rotation curv…
Probing the molecular gas content of galaxies in an over-dense group at z~0.7: a test case for environmental quenching
Jonathan Freundlich, Benoît Epinat, Thierry Contini +14
To probe the impact of group environment on molecular gas reservoirs at intermediate redshift, we observed the CO(2-1) emission in the galaxy group COSMOS-Gr30 at with…
Resolved molecular gas and star-formation in massive unquenched spirals : I. UGC 8179
Romane Cologni, Simon Flesch, Philippe Salomé +7
Recent studies have uncovered a rare population of super-massive (M* > 1e11 Msun) star-forming spiral galaxies, Super Spiral Galaxies (SSGs), whose existence challenges classical q…
Predicting HCN, HCO, multi-transition CO, and dust emission of star-forming galaxies -- Extension to luminous infrared galaxies and the role of cosmic ray ionization
B. Vollmer, J. Freundlich, P. Gratier +4
The specific star-formation rate of star-forming `main sequence' galaxies significantly decreased since z~1.5, due to the decreasing molecular gas fraction and star formation effic…
