OGLE 2004-BLG-254: a K3 III Galactic Bulge Giant spatially resolved by a single microlens
A. Cassan, J. -P. Beaulieu, P. Fouque +37
We present an analysis of OGLE 2004-BLG-254, a high-magnification and relatively short duration microlensing event in which the source star, a Bulge K3-giant, has been spatially re…
The Hubble Ultra Deep Field
Steven V. W. Beckwith, Massimo Stiavelli, Anton M. Koekemoer +12
This paper presents the Hubble Ultra Deep Field (HUDF), a one million second exposure of an 11 square minute-of-arc region in the southern sky with the Hubble Space Telescope. The…
A weak lensing estimate from GEMS of the virial to stellar mass ratio in massive galaxies to z~0.8
Catherine Heymans, Eric F. Bell, Hans-Walter Rix +14
We present constraints on the evolution of the virial to stellar mass ratio of galaxies with high stellar masses in the redshift range 0.2<z<0.8, by comparing weak lensing measurem…
Color, Structure, and Star Formation History of Dwarf Galaxies over the last ~3 Gyr with GEMS and SDSS
Fabio D. Barazza, Shardha Jogee, Hans-Walter Rix +7
We present a study of the colors, structural properties, and star formation histories for a sample of ~1600 dwarfs over look-back times of ~3 Gyr (z=0.002-0.25). The sample consist…
