An HI view of the on-going assembly of early-type galaxies: present and future observations
P. Serra, R. Morganti, T. A. Oosterloo +24
We present a preliminary analysis of the HI properties of early-type galaxies in the ATLAS3D sample. Using WSRT data for ~100 galaxies outside the Virgo cluster and data from the A…
Very High Gas Fractions and Extended Gas Reservoirs in z=1.5 Disk Galaxies
E. Daddi, F. Bournaud, F. Walter +10
We present evidence for very high gas fractions and extended molecular gas reservoirs in normal, near-infrared selected (BzK) galaxies at z~1.5, based on multi-configuration CO[2-1…
Formation of late-type spiral galaxies: gas return from stellar populations regulates disk destruction and bulge growth
Marie Martig, Frederic Bournaud
Spiral galaxies have most of their stellar mass in a large rotating disk, and only a modest fraction in a central spheroidal bulge. This poses a major challenge for cosmological mo…
The thick disks of spiral galaxies as relics from gas-rich, turbulent, clumpy disks at high redshift
Frederic Bournaud, Bruce G. Elmegreen, Marie Martig
The formation of thick stellar disks in spiral galaxies is studied. Simulations of gas-rich young galaxies show formation of internal clumps by gravitational instabilities, clump c…
How ubiquitous are massive starbursts in interacting galaxies?
P. Di Matteo, F. Bournaud, M. Martig +3
Many evidences exist for a connection between galaxy interactions and induced star formation. However, a large range of responses of galaxies to tidal interactions is found, both i…
Star formation and structure formation in galaxy collisions
Frederic Bournaud
A number of theoretical and simulation results on star and structure formation in galaxy interactions and mergers is reviewed, and recent hydrodynamic simulations are presented. Th…
