A Formation Scenario for the Disk of Satellites: Accretion of Satellites during Mergers
Rory Smith, Pierre-Alain Duc, Frederic Bournaud +1
The Disk of Satellites (DoS) observed in the Andromeda galaxy is a thin and extended group of satellites, nearly perpendicular to the disk plane, that share a common direction of r…
Non-linear violent disc instability with high Toomre's Q in high-redshift clumpy disc galaxies
Shigeki Inoue, Avishai Dekel, Nir Mandelker +3
We utilize zoom-in cosmological simulations to study the nature of violent disc instability (VDI) in clumpy galaxies at high redshift, --. Our simulated galaxies are not in…
Environmental regulation of cloud and star formation in galactic bars
F. Renaud, F. Bournaud, E. Emsellem +7
The strong time-dependence of the dynamics of galactic bars yields a complex and rapidly evolving distribution of dense gas and star forming regions. Although bars mainly host regi…
Gas dynamics in tidal dwarf galaxies: disc formation at z=0
F. Lelli, P. -A. Duc, E. Brinks +9
Tidal dwarf galaxies (TDGs) are recycled objects that form within the collisional debris of interacting/merging galaxies. They are expected to be devoid of non-baryonic dark matter…
A comparison of black hole growth in galaxy mergers with Gasoline and Ramses
J. M. Gabor, Pedro R. Capelo, Marta Volonteri +4
Supermassive black hole dynamics during galaxy mergers is crucial in determining the rate of black hole mergers and cosmic black hole growth. As simulations achieve higher resoluti…
High Resolution Imaging of PHIBSS z~2 Main Sequence Galaxies in CO J=1-0
A. D. Bolatto, S. R. Warren, A. K. Leroy +14
We present Karl G. Jansky Very Large Array observations of the CO J=1-0 transition in a sample of four main sequence galaxies. These galaxies are in the blue sequence of s…
