Spitzer and Hubble Constraints on the Physical Properties of the z~7 Galaxy Strongly Lensed by Abell 2218
E. Egami, J. -P. Kneib, G. H. Rieke +10
We report the detection of a z~7 galaxy strongly lensed by the massive galaxy cluster Abell 2218 (z=0.175) at 3.6 and 4.5 um using the Spitzer Observatory and at 1.1 um using the H…
Quantifying Substructure Using Galaxy-Galaxy Lensing in Distant Clusters
Priyamvada Natarajan, Jean-Paul Kneib, Ian Smail +1
We present high-resolution mass reconstructions for five massive cluster-lenses spanning a redshift range from z = 0.18 - 0.57 utilizing archival Hubble Space Telescope data and ap…
The 2dF Galaxy Redshift Survey: the local E+A galaxy population
Chris Blake, Michael Pracy, Warrick Couch +27
We select a sample of low-redshift (z ~ 0.1) E+A galaxies from the 2dF Galaxy Redshift Survey (2dFGRS). The spectra of these objects are defined by strong hydrogen Balmer absorptio…
Discovery of a Transient U-band Dropout in a Lyman-Break Survey: A Tidally-Disrupted Star at z = 3.3?
Daniel Stern, P. G. van Dokkum, Peter Nugent +8
We report the discovery of a transient source in the central regions of galaxy cluster Abell 267. The object, which we call "PALS1", was found in a survey aimed at identifying high…
Supernova / Acceleration Probe: A Satellite Experiment to Study the Nature of the Dark Energy
SNAP Collaboration, G. Aldering, W. Althouse +109
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's…
An Enlarged Cosmic Shear Survey with the William Herschel Telescope
Richard Massey, Alexandre Refregier, David J. Bacon +2
We report the results of a cosmic shear survey using the 4.2m William Herschel Telescope on La Palma, to a depth of R=25.8 (z~0.8), over 4 square degrees. The shear correlation fun…
