Type Ia Supernovae: Colors, Rates, and Progenitors
Epson Heringer, Chris Pritchet, Jason Kezwer +3
The rate of type Ia supernovae (SNe Ia) in a galaxy depends not only on stellar mass, but also on star formation history. Here we show that two simple observational quantities ($g-…
The regulation of star formation in cool-core clusters: imprints on the stellar populations of brightest cluster galaxies
S. I. Loubser, A. Babul, H. Hoekstra +4
A fraction of brightest cluster galaxies (BCGs) shows bright emission in the UV and the blue part of the optical spectrum, which has been interpreted as evidence of recent star for…
Joint Analysis of Cluster Observations: II. Chandra/XMM-Newton X-ray and Weak Lensing Scaling Relations for a Sample of 50 Rich Clusters of Galaxies
A. Mahdavi, H. Hoekstra, A. Babul +3
We present a study of multiwavelength X-ray and weak lensing scaling relations for a sample of 50 clusters of galaxies. Our analysis combines Chandra and XMM-Newton data using an e…
The Environmental Dependence of the Incidence of Galactic Tidal Features
Scott M. Adams, Dennis Zaritsky, David J. Sand +4
In a sample of 54 galaxy clusters (0.04<z<0.15) containing 3551 early-type galaxies suitable for study, we identify those with tidal features both interactively and automatically.…
The Canadian Cluster Comparison Project: weak lensing masses and SZ scaling relations
Henk Hoekstra, Andisheh Mahdavi, Arif Babul +1
The Canadian Cluster Comparison Project is a comprehensive multi-wavelength survey targeting 50 massive X-ray selected clusters of galaxies to examine baryonic tracers of cluster m…
A Giant Metrewave Radio Telescope/Chandra view of IRAS 09104+4109: A type 2 QSO in a cooling flow
Ewan O'Sullivan, Simona Giacintucci, Arif Babul +8
IRAS 09104+4109 is a rare example of a dust enshrouded type 2 QSO in the centre of a cool-core galaxy cluster. Previous observations of this z=0.44 system showed that as well as po…
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…
The Multi-Epoch Nearby Cluster Survey: type Ia supernova rate measurement in z~0.1 clusters and the late-time delay time distribution
David J. Sand, Melissa L. Graham, Chris Bildfell +8
We describe the Multi-Epoch Nearby Cluster Survey (MENeaCS), designed to measure the cluster Type Ia supernova (SN Ia) rate in a sample of 57 X-ray selected galaxy clusters, with r…
Intracluster supernovae in the Multi-epoch Nearby Cluster Survey
D. J. Sand, M. L. Graham, C. Bildfell +7
The Multi-Epoch Nearby Cluster Survey (MENeaCS) has discovered twenty-three cluster Type Ia supernovae (SNe) in the 58 X-ray selected galaxy clusters (0.05 < z < 0.15) surveyed. Fo…
Resurrecting the Red from the Dead: Optical Properties of BCGs in X-ray Luminous Clusters
C. Bildfell, H. Hoekstra, A. Babul +1
We present measurements of surface brightness and colour profiles for the brightest cluster galaxies (BCGs) in a sample of 48 X-ray luminous galaxy clusters. These data were obtain…
The impact of mergers on relaxed X-ray clusters - II. Effects on global X-ray and SZ properties and their scaling relations
Gregory B. Poole, Arif Babul, Ian G. McCarthy +4
We use the suite of simulations presented in Poole et al (2006) to examine global X-ray and Sunyaev-Zel'dovich (SZ) observables for systems of merging relaxed X-ray clusters. In al…
