Automated detection of galaxy-scale gravitational lenses in high resolution imaging data
Philip J. Marshall, David W. Hogg, Leonidas A. Moustakas +4
Lens modeling is the key to successful and meaningful automated strong galaxy-scale gravitational lens detection. We have implemented a lens-modeling "robot" that treats every brig…
A Multiply Imaged Luminous Infrared Galaxy Behind the Bullet Cluster
Anthony H. Gonzalez, Doug Clowe, Marusa Bradac +3
We present evidence for a Spitzer-selected luminous infrared galaxy (LIRG) behind the Bullet Cluster. The galaxy, originally identified in IRAC photometry as a multiply imaged sour…
The mass distribution of RX J1347-1145 from strong lensing
A. Halkola, H. Hildebrandt, T. Schrabback +5
High resolution HST/ACS images of the galaxy cluster RX J1347-1145 have enabled us to identify several new multiple image candidates in the cluster, including a 5 image system with…
Dark Matter and Baryons in the Most X-ray Luminous and Merging Galaxy Cluster RX J1347.5-1145
Maruša Bradač, Tim Schrabback, Thomas Erben +12
The galaxy cluster RX J1347-1145 is one of the most X-ray luminous and most massive clusters known. Its extreme mass makes it a prime target for studying issues addressing cluster…
Constraints on the Self-Interaction Cross-Section of Dark Matter from Numerical Simulations of the Merging Galaxy Cluster 1E 0657-5
Scott W. Randall, Maxim Markevitch, Douglas Clowe +2
(Abridged) We compare recent results from X-ray, strong lensing, weak lensing, and optical observations with numerical simulations of the merging galaxy cluster 1E0657-56. X-ray ob…
A direct empirical proof of the existence of dark matter
Douglas Clowe, Marusa Bradac, Anthony H. Gonzalez +4
We present new weak lensing observations of 1E0657-558 (z=0.296), a unique cluster merger, that enable a direct detection of dark matter, independent of assumptions regarding the n…
