An Overview of Extremely Large Telescopes Projects
R. G. Carlberg
IAU Symposium 232 allows a snapshot of ELTs at a stage when design work in several critical mass projects has been seriously underway for two to three years. The status and som eof…
Photometric selection of high-redshift type Ia supernovae
M. Sullivan, D. A. Howell, K. Perrett +26
We present a method for selecting high-redshift type Ia supernovae (SNe Ia) located via rolling SN searches. The technique, using both color and magnitude information of events fro…
Gemini Spectroscopy of Supernovae from SNLS: Improving High Redshift SN Selection and Classification
D. A. Howell, M. Sullivan, K. Perrett +22
We present new techiques for improving the efficiency of supernova (SN) classification at high redshift using 64 candidates observed at Gemini North and South during the first year…
Mass-to-Light Ratios of Galaxy Groups from Weak Lensing
Laura C. Parker, Michael J. Hudson, Ray G. Carlberg +1
We present the findings of our weak lensing study of a sample of 116 CNOC2 galaxy groups. The lensing signal is used to estimate the mass-to-light ratio of these galaxy groups. The…
A Hubble Space Telescope Snapshot Survey of Dynamically Close Galaxy Pairs in the CNOC2 Redshift Survey
D. R. Patton, J. K. Grant, L. Simard +3
We compare the structural properties of two classes of galaxies at intermediate redshift: those in dynamically close galaxy pairs, and those which are isolated. Both samples are se…
Gemini Deep Deep Survey VI: Massive Hdelta-strong galaxies at z=1
Damien Le Borgne, Roberto Abraham, Kathryne Daniel +11
We show that there has been a dramatic decline in the abundance of massive galaxies with strong Hdelta stellar absorption lines from z=1.2 to the present. These ``Hdelta-strong'',…
