Evolution in the Volumetric Type Ia Supernova Rate from the Supernova Legacy Survey
K. Perrett, M. Sullivan, A. Conley +23
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate (SNR_Ia) as a function of redshift for the first four years of data from the Canada-France-Hawaii Telescop…
An Efficient Approach to Obtaining Large Numbers of Distant Supernova Host Galaxy Redshifts
C. Lidman, V. Ruhlmann-Kleider, M. Sullivan +20
We use the wide-field capabilities of the 2dF fibre positioner and the AAOmega spectrograph on the Anglo-Australian Telescope (AAT) to obtain redshifts of galaxies that hosted supe…
The Type II Supernova Rate in z~0.1 Galaxy Clusters from the Multi-Epoch Nearby Cluster Survey
M. L. Graham, D. J. Sand, C. J. Bildfell +7
We present 7 spectroscopically confirmed Type II cluster supernovae (SNeII) discovered in the Multi-Epoch Nearby Cluster Survey, a supernova survey targeting 57 low redshift 0.05 <…
Evolution of the Red Sequence Giant to Dwarf Ratio in Galaxy Clusters out to z ~ 0.5
C. Bildfell, H. Hoekstra, A. Babul +9
We analyze deep g' and r' band data of 97 galaxy clusters imaged with MegaCam on the Canada-France-Hawaii telescope. We compute the number of luminous (giant) and faint (dwarf) gal…
