Radial Velocity Evidence for a Post-Mass-Transfer Massive Binary System NaSt1

Kittipong Wangnok, Samaporn Tinyanont, Ryan M. Lau +11

We present multi-epoch high-resolution optical spectroscopy () of the emission-line object NaSt1 to test its proposed binary nature, along with long-term multiba…

Early-type galaxies at z~1.3. IV. Scaling relations in different environments

A. Raichoor, S. Mei, S. A. Stanford +15

We present the Kormendy and mass-size relations for early-type galaxies (ETGs) as a function of environment at z~1.3. Our sample includes 76 visually classified ETGs with masses 10…

M/L and Color Evolution for A Deep Sample of M* Cluster Galaxies at z~1: The Formation Epoch and the Tilt of the Fundamental Plane

Brad P. Holden, Arjen van der Wel, Daniel D. Kelson +2

We have measured velocity dispersions for a sample of 36 galaxies with J < 21.2 or Mr < -20.6 mag in MS1054-03, a massive cluster of galaxies at z = 0.83. Our data are of uniformly…

The Ellipticities of Cluster Early-type Galaxies from z~1 to z~0: No Evolution in the Overall Distribution of Bulge-to-Disk Ratios

B. P. Holden, M. Franx, G. D. Illingworth +7

We have compiled a sample of early-type cluster galaxies from 0 < z < 1.3 and measured the evolution of their ellipticity distributions. Our sample contains 487 galaxies in 17 z>0.…

The Evolution of the Field and Cluster Morphology-Density Relation for Mass-Selected Samples of Galaxies

A. van der Wel, B. P. Holden, M. Franx +7

The Sloan Digital Sky Survey (SDSS) and photometric/spectroscopic surveys in the GOODS-South field (the Chandra Deep Field-South, CDFS) are used to construct volume-limited, stella…

VLT and ACS observations of RDCS J1252.9-2927: dynamical structure and galaxy populations in a massive cluster at z=1.237

R. Demarco, P. Rosati, C. Lidman +26

We present results from an extensive spectroscopic survey, carried out with VLT FORS, and from an extensive multiwavelength imaging data set from the HST Advanced Camera for Survey…
