The X-ray Cluster Normalization of the Matter Power Spectrum
J. Patrick Henry, August E. Evrard, Henk Hoekstra +2
The number density of galaxy clusters provides tight statistical constraints on the matter fluctuation power spectrum normalization, traditionally phrased in terms of sigma_8, the…
Sersiclets - A Matched Filter Extension of Shapelets for Weak Lensing Studies
Wai-Hin Wayne Ngan, Ludovic Van Waerbeke, Andisheh Mahdavi +2
The precision study of dark matter using weak lensing by large scale structure is strongly constrained by the accuracy with which one can measure galaxy shapes. Several methods hav…
Optical Spectroscopy of Type Ia Supernovae
T. Matheson, R. P. Kirshner, P. Challis +19
We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spect…
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…
