The accretion origin of the Milky Way's stellar halo
Eric F. Bell, Daniel B. Zucker, Vasily Belokurov +15
We have used data from the Sloan Digital Sky Survey (SDSS) Data Release 5 to explore the overall structure and substructure of the stellar halo of the Milky Way using about 4 milli…
GEMS: Galaxy fitting catalogues and testing parametric galaxy fitting codes
Boris Häußler, Daniel H. McIntosh, Marco Barden +14
In the context of measuring structure and morphology of intermediate redshift galaxies with recent HST/ACS surveys, we tune, test, and compare two widely used fitting codes (GALFIT…
The First Release COSMOS Optical and Near-IR Data and Catalog
P. Capak, H. Aussel, M. Ajiki +54
We present imaging data and photometry for the COSMOS survey in 15 photometric bands between 0.3um and 2.4um. These include data taken on the Subaru 8.3m telescope, the KPNO and CT…
An integral field spectroscopic survey for high redshift damped Lyman-alpha galaxies
L. Christensen, L. Wisotzki, M. M. Roth +3
We search for galaxy counterparts to damped Lyman-alpha absorbers (DLAs) at z>2 towards nine quasars, which have 14 DLAs and 8 sub-DLAs in their spectra. We use integral field spec…
Spatial decomposition of on-nucleus spectra of quasar host galaxies
Knud Jahnke, Lutz Wisotzki, Frederic Courbin +1
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…
