Morphologies and stellar populations of galaxies in the core of Abell 2218
S. F. Sanchez, N. Cardiel, M. Verheijen +2
SUMMARIZED ABSTRACT: We present a study of the stellar populations and morphologies of galaxies in the core of the galaxy cluster Abell 2218. Integral field spectroscopy was obtain…
HII Galaxies with 3D Spectroscopy
C. Kehrig, J. M. Vilchez, S. F. Sanchez +3
We present our ongoing work on integral field spectroscopy of three prototypical HII galaxies: IIZw70, IIZw71 and IZw18. The data are mainly used to study the ionized gas and stell…
Constraints on an optical afterglow and on supernova light following the short burst GRB 050813
P. Ferrero, S. F. Sanchez, D. A. Kann +18
We report early follow-up observations of the error box of the short burst 050813 using the telescopes at Calar Alto and at Observatorio Sierra Nevada (OSN), followed by deep VLT/F…
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…
Galaxies in the Hubble Ultra Deep Field: I. Detection, Multiband Photometry, Photometric Redshifts, and Morphology
Dan Coe, Narciso Benitez, Sebastian F. Sanchez +3
We present aperture-matched PSF-corrected BVi'z'JH photometry and Bayesian photometric redshifts (BPZ) for objects detected in the Hubble Ultra Deep Field (UDF), 8,042 of which are…
A jet-cloud interaction in the 3C 196 environment
L. Christensen, K. Jahnke, L. Wisotzki +3
Powerful radio galaxies and radio-loud quasars at high redshifts are frequently associated with extended emission-line regions (EELRs). Here we investigate the [O II] EELR around t…
