Crowded Cluster Cores: Algorithms for Deblending in Dark Energy Survey Images
Yuanyuan Zhang, Timothy A. McKay, Emmanuel Bertin +4
Deep optical images are often crowded with overlapping objects. This is especially true in the cores of galaxy clusters, where images of dozens of galaxies may lie atop one another…
Orientation Bias of Optically Selected Galaxy Clusters and Its Impact on Stacked Weak Lensing Analyses
Jörg P. Dietrich, Yuanyuan Zhang, Jeeseon Song +15
Weak-lensing measurements of the averaged shear profiles of galaxy clusters binned by some proxy for cluster mass are commonly converted to cluster mass estimates under the assumpt…
A Parametrized Galaxy Catalog Simulator For Testing Cluster Finding, Mass Estimation and Photometric Redshift Estimation in Optical and Near Infrared Surveys
Jeeseon Song, Joseph J. Mohr, Wayne A. Barkhouse +2
We present a galaxy catalog simulator which turns N-body simulations with subhalos into multiband photometric mocks. The simulator assigns galaxy properties to each subhalo to repr…
Weak lensing of the high redshift SNIa sample
Liliya L. R. Williams, Jeeseon Song
The current sample of high-redshift Supernova Type Ia, which combines results from two teams, High-z Supernova Search Team and Supernova Cosmology Project, is analyzed for the effe…
