Constraining the Evolution of the Most Massive Galaxies Since z~1
Richard Cool
2:00pm|Bloomberg Hall Astrophysics Library
The popular model for the formation of early-type galaxies is the hierarchical merging scenario. However, the details and frequency of merging are not yet known, particularly in dense environments. The high-mass end of the galaxy luminosity function...

Cold and Warm Gas in NGC 2974: Inferring the Shape of its Dark Matter Halo
Anne-Marie Weijmans
11:30am|Bloomberg Hall Astrophysics Library
In this talk I will discuss observations of ionized and neutral gas in the early-type galaxy NGC 2974. We extracted rotation curves both for the warm and cold gas, and applied the asymmetric drift correction to the velocities obtained from the...

Multiple Galaxy Mergers, and Cosmological Context, and Elliptical Galaxy Formation
Greg Novak
11:30am|Bloomberg Hall Astrophysics Library
I have performed a set of hydrodynamic simulations of multiple galaxy mergers both with and without a cosmological context using Gadget. Using a set of existing simulations of binary mergers of gas-rich spiral galaxies, I found that the simulated...
