The Complete Local Volume Groups Sample -- IV. Star formation and gas content in group-dominant galaxies
Konstantinos Kolokythas, Sravani Vaddi, Ewan O'Sullivan +5
Using multi-band data we examine the star formation activity of the nearby group-dominant early-type galaxies of the Complete Local-volume Groups Sample (CLoGS), and the relation b…
Molecular gas along the old radio jets of the cluster-central type 2 quasar IRAS 09104+4109
Ewan O'Sullivan, Françoise Combes, Arif Babul +4
We present Northern Extended Millimeter Array (NOEMA) CO(2-1) maps of the z=0.4418 cluster-central QSO IRAS 09104+4109, which trace ~4.5x10^10 Msol of molecular gas in and around t…
Simulating Groups and the IntraGroup Medium: The Surprisingly Complex and Rich Middle Ground Between Clusters and Galaxies
Benjamin D. Oppenheimer, Arif Babul, Yannick Bahé +2
Galaxy groups are more than an intermediate scale between clusters and halos hosting individual galaxies, they are crucial laboratories capable of testing a range of astrophysics f…
The Dawn of Disk Formation in a Milky Way-sized Galaxy Halo: Thin Stellar Disks at
Tomas Tamfal, Lucio Mayer, Thomas R. Quinn +5
We present results from \textsc{GigaEris}, a cosmological, -body hydrodynamical "zoom-in" simulation of the formation of a Milky Way-sized galaxy halo with unprecedented resolut…
