Molecular gas in distant brightest cluster galaxies

G. Castignani, F. Combes, P. Salomé +1

The stellar mass assembly of brightest cluster galaxies (BCGs) is still debated. We have observed in CO with the IRAM-30m two star forming BCGs belonging to SpARCS clusters, 3C 244…

A mass threshold for galactic gas discs by spin flips

Avishai Dekel, Omri Ginzburg, Fangzhou Jiang +4

We predict, analytically and by simulations, that gas discs tend to survive only in haloes above a threshold mass (stellar mass )…

Unveiling Sizes of Compact AGN Hosts with ALMA

Yu-Yen Chang, Emeric Le Floc'h, Stéphanie Juneau +7

We present rest-frame far-infrared (FIR) and optical size measurements of AGN hosts and star-forming galaxies in the COSMOS field, enabled by high-resolution ALMA/1 mm (0.1 arcsec…

On the Mass Assembly History of the Local Group

Edoardo Carlesi, Yehuda Hoffman, Stefan Gottlöber +4

In this work an ensemble of simulated Local Group analogues is used to constrain the properties of the mass assembly history of the Milky Way (MW) and Andromeda (M31) galaxies. The…

Nearly all Massive Quiescent Disk Galaxies have a Surprisingly Large Atomic Gas Reservoir

Chengpeng Zhang, Yingjie Peng, Luis C. Ho +11

The massive galaxy population above the characteristic Schechter mass M*~10^10.6 Msun contributes to about half of the total stellar mass in the local Universe. These massive galax…

The SFR-radius connection: data and implications for wind strength and halo concentration

Lin Lin, S. M. Faber, David C. Koo +26

This paper is one in a series that explores the importance of radius as a second parameter in galaxy evolution. The topic investigated here is the relationship between star formati…
