Galaxy-Mass Correlations on 10 Mpc Scales in the Deep Lens Survey
Ami Choi, J. Anthony Tyson, Chris B. Morrison +4
We examine the projected correlation of galaxies with mass from small scales (<few hundred kpc) where individual dark matter halos dominate, out to 15 Mpc where correlated large-sc…
Discovery of a Dissociative Galaxy Cluster Merger with Large Physical Separation
William A. Dawson, David Wittman, Myungkook Jee +10
We present DLSCL J0916.2+2951 (z=0.53), a newly discovered major cluster merger in which the collisional cluster gas has become dissociated from the collisionless galaxies and dark…
Shear-Selected Clusters From the Deep Lens Survey III: Masses from Weak Lensing
Alexandra Abate, D. Wittman, V. E. Margoniner +4
We present weak lensing mass estimates of seven shear-selected galaxy cluster candidates from the Deep Lens Survey. The clusters were previously identified as mass peaks in converg…
Photometric Redshifts and Photometry Errors
D. Wittman, P. Riechers, V. E. Margoniner
We examine the impact of non-Gaussian photometry errors on photometric redshift performance. We find that they greatly increase the scatter, but this can be mitigated to some exten…
Photometric Redshifts and Signal-to-Noise
V. E. Margoniner, D. M. Wittman
We investigate the impact of photometric signal-to-noise (S/N) on the precision of photometric redshifts in multi-band imaging surveys, using both simulations and real data. We sim…
Probing the Relation Between X-ray-Derived and Weak-Lensing-Derived Masses for Shear-Selected Galaxy Clusters: I. A781
Neelima Sehgal, John P. Hughes, David Wittman +4
We compare X-ray and weak-lensing masses for four galaxy clusters that comprise the top-ranked shear-selected cluster system in the Deep Lens Survey. The weak-lensing observations…
