Halo masses for optically-selected and for radio-loud AGN from clustering and galaxy-galaxy lensing
Rachel Mandelbaum, Cheng Li, Guinevere Kauffmann +1
We compute two-point correlation functions and measure the shear signal due to galaxy-galaxy lensing for 80,000 optically identified and 5,700 radio-loud AGN from Data Release 4 (D…
Improved optical mass tracer for galaxy clusters calibrated using weak lensing measurements
Reinabelle Reyes, Rachel Mandelbaum, Christopher M. Hirata +2
We develop an improved mass tracer for clusters of galaxies from optically observed parameters, and calibrate the mass relation using weak gravitational lensing measurements. We em…
Precision photometric redshift calibration for galaxy-galaxy weak lensing
R. Mandelbaum, U. Seljak, C. M. Hirata +26
Accurate photometric redshifts are among the key requirements for precision weak lensing measurements. Both the large size of the Sloan Digital Sky Survey (SDSS) and the existence…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters I: Measurements
Erin S. Sheldon, David E. Johnston, Ryan Scranton +12
This is the first in a series of papers on the weak lensing effect caused by clusters of galaxies in Sloan Digital Sky Survey. The photometrically selected cluster sample, known as…
Intrinsic galaxy alignments from the 2SLAQ and SDSS surveys: luminosity and redshift scalings and implications for weak lensing surveys
Christopher M. Hirata, Rachel Mandelbaum, Mustapha Ishak +5
Correlations between intrinsic shear and the density field on large scales, a potentially important contaminant for cosmic shear surveys, have been robustly detected at low redshif…
The Shear TEsting Programme 2: Factors affecting high precision weak lensing analyses
Richard Massey, Catherine Heymans, Joel Berge +28
The Shear TEsting Programme (STEP) is a collaborative project to improve the accuracy and reliability of weak lensing measurement, in preparation for the next generation of wide-fi…
