Observational constraints on the co-evolution of supermassive black holes and galaxies
X. Z. Zheng, E. F. Bell, R. S. Somerville +6
The star formation rate (SFR) and black hole accretion rate (BHAR) functions are measured to be proportional to each other at z < ~3. This close correspondence between SF and BHA w…
Interacting Galaxies in the A901/902 Supercluster with STAGES
A. L. Heiderman, S. Jogee, I. Marinova +22
We present a study of galaxy mergers and the influence of environment in the Abell 901/902 supercluster at z~0.165. We use HST ACS F606W data from the STAGES survey, COMBO-17, Spit…
Empirical Constraints on the Evolution of the Relationship between Black Hole and Galaxy Mass: Scatter Matters
Rachel S. Somerville
I investigate whether useful constraints on the evolution of the relationship between galaxy mass and black hole (BH) mass can be obtained from recent measurements of galaxy stella…
Less than 10 percent of star formation in z=0.6 massive galaxies is triggered by major interactions
Aday R. Robaina, Eric F. Bell, Rosalind E. Skelton +26
Both observations and simulations show that major tidal interactions or mergers between gas-rich galaxies can lead to intense bursts of starformation. Yet, the average enhancement…
Can Gas prevent the Destruction of Thin Stellar Discs by Minor Mergers?
Benjamin P. Moster, Andrea V. Maccio', Rachel S. Somerville +2
We study the effect of dissipational gas physics on the vertical heating and thickening of disc galaxies during minor mergers. We produce a suite of minor merger simulations for Mi…
The effect of dry mergers on the color-magnitude relation of early-type galaxies
Rosalind E. Skelton, Eric F. Bell, Rachel S. Somerville
We investigate the effect of dry merging on the color-magnitude relation (CMR) of galaxies and find that the amount of merging predicted by a hierarchical model results in a red se…
