The X-ray Properties of Early-Type Galaxies in the Extended Chandra Deep Field-South
B. D. Lehmer, W. N. Brandt, D. M. Alexander +8
We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Fiel…
A weak lensing estimate from GEMS of the virial to stellar mass ratio in massive galaxies to z~0.8
Catherine Heymans, Eric F. Bell, Hans-Walter Rix +14
We present constraints on the evolution of the virial to stellar mass ratio of galaxies with high stellar masses in the redshift range 0.2<z<0.8, by comparing weak lensing measurem…
An Orphan in the "Field of Streams"
V. Belokurov, N. W. Evans, M. J. Irwin +19
We use Sloan Digital Sky Survey Data Release 5 photometry and spectroscopy to study a tidal stream that extends over 50 degrees in the North Galactic Cap. From the analysis of the…
Eight billion years of disk galaxy evolution: no galaxy is an island
Eric F. Bell, Marco Barden, Xianzhong Zheng +7
We present a brief discussion of the evolution of disk galaxy stellar masses, sizes, rotation velocities, and star formation rates over the last eight billion years. Recent observa…
The stellar masses of 25000 galaxies at 0.2<z<1.0 estimated by the COMBO-17 survey
Andrea Borch, Klaus Meisenheimer, Eric F. Bell +6
We present an analysis of stellar mass estimates for a sample of 25000 galaxies from the COMBO-17 survey over the interval 0.2<z<1.0. We have developed, implemented, and tested a n…
Color, Structure, and Star Formation History of Dwarf Galaxies over the last ~3 Gyr with GEMS and SDSS
Fabio D. Barazza, Shardha Jogee, Hans-Walter Rix +7
We present a study of the colors, structural properties, and star formation histories for a sample of ~1600 dwarfs over look-back times of ~3 Gyr (z=0.002-0.25). The sample consist…
