An Explanation for the Observed Weak Size Evolution of Disk Galaxies
Rachel S. Somerville, Marco Barden, Hans-Walter Rix +14
Surveys of distant galaxies with the Hubble Space Telescope and from the ground have shown that there is only mild evolution in the relationship between radial size and stellar mas…
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…
Discovery of a Cool Planet of 5.5 Earth Masses Through Gravitational Microlensing
J. -P. Beaulieu, D. P. Bennett, P. Fouque +46
In the favoured core-accretion model of formation of planetary systems, solid planetesimals accumulate to build up planetary cores, which then accrete nebular gas if they are suffi…
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…
