PAndAS in the mist: The stellar and gaseous mass within the halos of M31 and M33

Geraint F. Lewis, Robert Braun, Alan W. McConnachie +12

Large scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substruc…

Unearthing Foundations of a Cosmic Cathedral: Searching the Stars for M33's Halo

Robert Cockcroft, Alan W. McConnachie, William E. Harris +9

We use data from the Pan-Andromeda Archaeological Survey (PAndAS) to search for evidence of an extended halo component belonging to M33 (the Triangulum Galaxy). We identify a popul…

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…

Isotropic Heating of Galaxy Cluster Cores via Rapidly Reorienting AGN Jets

Arif Babul, Prateek Sharma, Christopher S. Reynolds

AGN jets carry more than sufficient energy to stave off catastrophic cooling of the intracluster medium (ICM) in the cores of cool-core clusters. However, in order to prevent catas…

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…

LoCuSS: A Dynamical Analysis of X-ray AGN in Local Clusters

C. P. Haines, M. J. Pereira, A. J. R. Sanderson +7

We present a study of the distribution of X-ray AGN in a representative sample of 26 massive clusters at 0.15<z<0.30, combining Chandra observations with highly complete spectrosco…

A Study of the Dark Core in A520 with Hubble Space Telescope: The Mystery Deepens

M. J. Jee, A. Mahdavi, H. Hoekstra +4

We present a Hubble Space Telescope/Wide Field Planetary Camera 2 weak-lensing study of A520, where a previous analysis of ground-based data suggested the presence of a dark mass c…

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…
