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…
LSST: from Science Drivers to Reference Design and Anticipated Data Products
Željko IveziÄ, Steven M. Kahn, J. Anthony Tyson +310
(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a sin…
The LSST Data Management System
Mario JuriÄ, Jeffrey Kantor, K-T Lim +62
The Large Synoptic Survey Telescope (LSST) is a large-aperture, wide-field, ground-based survey system that will image the sky in six optical bands from 320 to 1050 nm, uniformly c…
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…
LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
