Measuring the Environmental Dependence of Galaxy Haloes with Weak Lensing
(University of Waterloo, 2013-09-04)
We investigate the uses of gravitational lensing for analysing the dark matter haloes around galaxies, comparing galaxies within groups and clusters to those in the field. We consider two cases: when only photometric ...
Group-finding with photometric redshifts: The Photo-z Probability Peaks algorithm
(University of Waterloo, 2010-01-25)
We present a galaxy group-finding algorithm, the Photo-z Probability Peaks (P3) algorithm, optimized for locating small galaxy groups using photometric redshift data by searching for peaks in the signal-to-noise of the ...
