The galaxy-dark matter bias in the Garching-Bonn Deep Survey
Patrick Simon, Peter Schneider, Thomas Erben +3
We measured the bias and correlation factor of galaxies with respect to the dark matter using the aperture statistics including the aperture mass from weak gravitational lensing. T…
The Wide Field Imager Lyman-Alpha Search (WFILAS) for Galaxies at Redshift ~5.7: I. A Spatially Compact Lyman-alpha Emitting Galaxy at Redshift 5.721
Eduard Westra, D. Heath Jones, Chris E. Lidman +6
We report the spectroscopic confirmation of a compact \lya emitting galaxy at . A FORS2 spectrum of the source shows a strong asymmetric line with a flux of 5$\times10^{-1…
The Evolution of Early-type Red Galaxies with the GEMS Survey: Luminosity-size and Stellar Mass-size Relations Since z=1
Daniel H. McIntosh, Eric F. Bell, Hans-Walter Rix +14
We combine HST/ACS imaging from the GEMS survey with redshifts and rest-frame quantities from COMBO-17 to study the evolution of morphologically early-type galaxies with red colors…
Evolution of AGN - an optical view
C. Wolf
This article discusses the our changing knowledge of the evolution of AGN from an optical perspective. It focusses on optically-unobscured (type-1) AGN as it is much trickier to in…
Cosmological weak lensing with the HST GEMS survey
Catherine Heymans, Michael L. Brown, Marco Barden +16
We present our cosmic shear analysis of GEMS, one of the largest wide-field surveys ever undertaken by the Hubble Space Telescope. Imaged with the Advanced Camera for Surveys (ACS)…
Galaxy-galaxy lensing studies from COMBO-17
Martina Kleinheinrich, Hans-Walter Rix, Peter Schneider +4
We study the dark matter halos of galaxies with galaxy-galaxy lensing using the COMBO-17 survey. This survey offers an unprecedented data set for studying lens galaxies at z=0.2-0.…
