The Supernova Legacy Survey: Measurement of Omega_M, Omega_Lambda and w from the First Year Data Set
P. Astier, J. Guy, N. Regnault +39
We present distance measurements to 71 high redshift type Ia supernovae discovered during the first year of the 5-year Supernova Legacy Survey (SNLS). These events were detected an…
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…
AB Doradus C: Age, Spectral Type, Orbit, and Comparison to Evolutionary Models
E. L. Nielsen, L. M. Close, J. C. Guirado +5
We expand upon the results of Close et al. 2005 regarding the young, low-mass object AB Dor C and its role as a calibration point for theoretical tracks. We present an improved spe…
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…
Photometric monitoring of the doubly imaged quasar UM673: possible evidence for chromatic microlensing
Th. Nakos, F. Courbin, J. Poels +12
We present the results of two-band CCD photometric monitoring of the gravitationally lensed quasar Q 0142-100 (UM 673).The data, obtained at ESO-La Silla with the 1.54 m Danish tel…
Confirmation of two extended objects along the line of sight to PKS1830-211 with ESO-VLT adaptive optics imaging
G. Meylan, F. Courbin, C. Lidman +2
We report on new high-resolution near-infrared images of the gravitationally lensed radio source PKS1830-211, a quasar at z=2.507. These adaptive optics observations, taken with th…
