The Evolutionary History of Galactic Bulges: Photometric and Spectroscopic Studies of Distant Spheroids in the GOODS Fields
Lauren A. MacArthur, Richard S. Ellis, Tommaso Treu +3
We report on the first results of a new study aimed at understanding the diversity and evolutionary history of distant galactic bulges in the context of now well-established trends…
The Fundamental Plane of Bulges at Intermediate Redshift
Lauren A. MacArthur, Richard S. Ellis, Tommaso Treu
We report on a new study aimed at understanding the diversity and evolutionary properties of distant galactic bulges in the context of well-established trends for pure spheroidal g…
Scaling Relations of Spiral Galaxies
S. Courteau, A. A. Dutton, F. van den Bosch +4
We construct a large data set of global structural parameters for 1300 field and cluster spiral galaxies and explore the joint distribution of luminosity L, optical rotation veloci…
Stellar Populations in Spiral Galaxies
Lauren A. MacArthur, Jesus Gonzalez, Stephane Courteau
We report preliminary results of the characterization of bulge and inner disk stellar populations for 8 nearby spiral galaxies using Gemini/GMOS. The long-slit spectra extend out t…
The Dynamical Distinction between Elliptical and Lenticular Galaxies in Distant Clusters: Further Evidence for the Recent Origin of S0 Galaxies
Sean M. Moran, Boon Liang Loh, Richard S. Ellis +3
We examine resolved spectroscopic data obtained with the Keck II telescope for 44 spheroidal galaxies in the fields of two rich clusters, Cl0024+16 (z=0.40) and MS0451-03 (z=0.54),…
