Cluster Evolution Since z~1
R. Demarco, J. P. Blakeslee, H. C. Ford +8
We have used the Advanced Camera for Surveys (ACS) on the HST to obtain optical imaging of a sample of 8 galaxy clusters in the redshift range 0.8 < z < 1.3. The ACS data provides…
WFILAS: Wide Field Imager Lyman Alpha Search
Eduard Westra, D. Heath Jones, Chris Lidman +6
The Wide Field Imager Lyman-Alpha Search (WFILAS) is a search for Lya emitting galaxies at z~5.7. Deep images from the Wide Field Imager (WFI) on the ESO/MPI 2.2m telescope have be…
Discovery of a high-redshift Einstein ring
R. A. Cabanac, D. Valls-Gabaud, A. O. Jaunsen +2
We report the discovery of a partial Einstein ring of radius 1.48arcsec produced by a massive (and seemingly isolated) elliptical galaxy. The spectroscopic follow-up at the VLT rev…
The Wide Field Imager Lyman-Alpha Search (WFILAS) for Galaxies at Redshift ~5.7: I. A Spatially Compact Lyman-alpha Emitting Galaxy at Redshift 5.721
Eduard Westra, D. Heath Jones, Chris E. Lidman +6
We report the spectroscopic confirmation of a compact \lya emitting galaxy at . A FORS2 spectrum of the source shows a strong asymmetric line with a flux of 5$\times10^{-1…
An optical time delay for the double gravitational lens system FBQ 0951+2635
P. Jakobsson, J. Hjorth, I. Burud +3
We present optical R-band light curves of the double gravitationally lensed quasar FBQ 0951+2635 from observations obtained at the Nordic Optical Telescope between March 1999 and J…
