Deciphering the formation of early-type galaxies using large scale dynamical stellar maps

Caroline Foster

As part of the SAGES Legacy Unifying Globulars and Galaxies Survey (SLUGGS), we have obtained large scale (out to 2.6 effective radii), spatially resolved stellar kinematic maps for over 25 early-type galaxies. I will present these kinematic maps, kinemetry fits and variations in the angular momentum as a function of galactocentric radius. Changes in the dynamical support (rotation versus pressure) as a function of radius in multiple systems emphasize the need to survey the faint outskirts in order to obtain a complete picture. These results are used to infer the individual assembly history of the galaxies in our sample.
