Bars in Disk-dominated and Bulge-dominated Galaxies at z ~ 0: New Insights from ~3600 SDSS Galaxies
We present a study of large-scale bars in the local universe, based on a large sample of 3692 galaxies, with 18.5 ≤ Mg < − 22.0 mag and redshift 0.01 ≤ z < 0.03, drawn from the Sloan Digitized SkyExpand

OBSCURED STAR FORMATION IN INTERMEDIATE-DENSITY ENVIRONMENTS: A SPITZER STUDY OF THE ABELL 901/902 SUPERCLUSTER
We explore the amount of obscured star formation as a function of environment in the Abell 901/902 (A901/902) supercluster at z = 0.165 in conjunction with a field sample drawn from the A901 and CDFSExpand

A deep, narrow J-band search for protogalactic Lyα emission at redshifts z~ 9
We present a deep, narrow J-band search for protogalactic Lya emission at redshifts z ∼ 9. We combine an exceptionally deep image of the Hubble Deep Field South, obtained using a narrow-band filterExpand

Stellar populations of early-type galaxies in different environments. III. Line-strength gradients
Aims. This is the third paper of a series devoted to the study of the stellar content of early-type galaxies. The goal of the series is to set constraints on the evolutionary status of these objects.Expand

STAGES: the Space Telescope A901/2 Galaxy Evolution Survey
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide rangeExpand

Satellite galaxies in semi-analytic models of galaxy formation with sterile neutrino dark matter
The sterile neutrino is a viable darkmatter candidate that can be produced in the early Universe via non-equilibrium processes, and would therefore possess a highly non-thermal spectrum of primordialExpand

Infrared and Raman studies of the Verwey transition in magnetite
We present infrared and Raman measurements of magnetite (Fe3O4). This material is known to undergo a metal-insulator and a structural transition (Verwey transition) at T-V = 120 K. The structuralExpand

COSMIC EVOLUTION OF VIRIAL AND STELLAR MASS IN MASSIVE EARLY-TYPE GALAXIES*
We measure the average mass properties of a sample of 41 strong gravitational lenses at moderate redshift (z similar to 0.4-0.9) and present the lens redshift for six of these galaxies for the firstExpand

Uvudf: Ultraviolet Imaging Of The Hubble Ultra Deep Field With Wide-Field Camera 3
We present an overview of a 90 orbit Hubble Space Telescope treasury program to obtain near-ultraviolet imaging of the Hubble Ultra Deep Field using the Wide Field Camera 3 UVIS detector with theExpand

Spatial decomposition of on-nucleus spectra of quasar host galaxies*
In order to study the host galaxies of type 1 (broad-line) quasars, we present a semi-analytic modelling method to decompose the on-nucleus spectra of quasars into nuclear and host galaxy channels.Expand
