J. M. Lotz et al., "The Evolution of Galaxy Mergers and Morphology at z < 1.2 in the Extended Groth Strip.", submitted to ApJ

Merger rates and galaxy morphologies are measured for ~1500 galaxies from HST ACS images. Merger rates remain roughly constant at a few percent over time, but the morphological makeup of the population changes significantly after z = 1.

S. P. Willner et al., "Mid-infrared Indentification of 6 cm Radio Source Counterparts in the Extended Groth Strip."

IRAC spectral energy distributions are analyzed for newly-discovered distant 6 cm radio galaxies. Most galaxies have stellar-dominated IRAC spectra (in contrast to power laws) and from their color appear to be bulge-dominated.

A. Georgakakis et al. 2006, "A Deep Chandra survey of the Groth Strip. II. Optical identification of the X-ray sources."

This paper analyzes the redshift distribution and N_H column densities of ~100 Chandra X-ray source in the Extended Groth Strip.

P. Barmby et al. 2006, "Mid-infrared properties of X-ray sources in the Extended Groth Strip"

IRAC spectral energy distributions are compiled for 150 X-ray detected AGN galaxies. The SED shapes scatter widely, with only 40% showing power laws at near-IR wavelengths.
