The relation between star formation, morphology and local density in high redshift clusters and groups
Bianca M. Poggianti, Vandana Desai, Rose Finn +17
We investigate how the [OII] properties and the morphologies of galaxies in clusters and groups at z=0.4-0.8 depend on projected local galaxy density, and compare with the field at…
The extreme, red afterglow of GRB 060923A: Distance or dust?
N. R. Tanvir, A. J. Levan, E. Rol +16
Gamma-ray bursts are powerful probes of the early universe, but locating and identifying very distant GRBs remains challenging. We report here the discovery of the K-band afterglow…
Spectroscopy of clusters in the ESO distant cluster survey (EDisCS).II. Redshifts, velocity dispersions, and substructure for clusters in the last 15 fields
Bo Milvang-Jensen, Stefan Noll, Claire Halliday +17
AIMS. We present spectroscopic observations of galaxies in 15 survey fields as part of the ESO Distant Cluster Survey (EDisCS). We determine the redshifts and velocity dispersions…
Detection of GRB 060927 at z = 5.47: Implications for the Use of Gamma-Ray Bursts as Probes of the End of the Dark Ages
A. E. Ruiz-Velasco, H. Swan, E. Troja +54
We report on follow-up observations of the GRB 060927 using the ROTSE-IIIa telescope and a suite of larger aperture ground-based telescopes. An optical afterglow was detected 20 s…
Probing the truncation of galaxy dark matter halos in high density environments from hydrodynamical N-body simulations
Marceau Limousin, Jesper Sommer-Larsen, Priyamvada Natarajan +1
We analyze high resolution, N-body hydrodynamical simulations of fiducial galaxy clusters to probe tidal stripping of the dark matter subhalos. These simulations include a prescrip…
The X-ray properties of optically-selected z>0.6 clusters in the ESO Distant Cluster Survey
O. Johnson, P. Best, D. Zaritsky +11
We present XMM-Newton observations of three optically-selected z > 0.6 clusters from the ESO Distant Cluster Survey (EDisCS), comprising the first results of a planned X-ray survey…
