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
We investigated the impact of group environment on molecular gas reservoirs at an intermediate redshift by observing the CO(2-1) emission from the galaxy group COSMOS-Gr30 at $z \s…

Starbursts hiding in the main sequence: a pathway toward quenching?
Florent Renaud, Katarina Kraljic, Jonathan Freundlich +10
Star-forming galaxies spend most of their lifetimes on the star-forming main sequence, which establishes a tight empirical and statistical relation between stellar mass and star-fo…

SQ-A: A Collision Triggered Starburst in Intra-Group Medium of Stephan's Quintet
C. K. Xu, C. Cheng, M. S. Yun +12
We present new observational evidence supporting the hypothesis that SQ-A, a starburst in the intra-group medium (IGrM) of Stephan's Quintet (SQ), is triggered by a high-speed coll…
