Enhanced lensing rate by clustering of massive galaxies: newly discovered systems in the SLACS fields
Elisabeth R. Newton, Philip J. Marshall, Tommaso Treu
[Abridged] We exploit the clustering of massive galaxies to perform a high efficiency imaging search for gravitational lenses. Our dataset comprises 44 fields imaged by the Hubble…
The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA)
Leonidas A Moustakas, Adam J Bolton, Jeffrey T Booth +15
(abridged) The Observatory for Multi-Epoch Gravitational Lens Astrophysics (OMEGA) is a mission concept for a 1.5-m near-UV through near-IR space observatory that will be dedicated…
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…
LSST: from Science Drivers to Reference Design and Anticipated Data Products
Željko Ivezić, 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…
Dissecting the Gravitational Lens B1608+656. I. Lens Potential Reconstruction
S. H. Suyu, P. J. Marshall, R. D. Blandford +4
Strong gravitational lensing is a powerful technique for probing galaxy mass distributions and for measuring cosmological parameters. We present a pixelated approach to modeling si…
Late-time observations of SN2006gy: Still Going Strong
Nathan Smith, Ryan J. Foley, Joshua S. Bloom +9
Owing to its extremely high luminosity and long duration, SN2006gy radiated more energy in visual light than any other known SN. Two hypotheses to explain its high luminosity -- th…
The Sloan Lens ACS Survey. VI: Discovery and analysis of a double Einstein ring
Raphael Gavazzi, Tommaso Treu, Leon V. E. Koopmans +4
We report the discovery of two concentric Einstein rings around the gravitational lens SDSSJ0946+1006, as part of the Sloan Lens ACS Survey. The main lens is at redshift zl=0.222,…
AMUSE-Virgo I. Super-massive black holes in low-mass spheroids
Elena Gallo, Tommaso Treu, Jeremy Jacob +3
We present the first results from the AGN Multiwavelength Survey of Early-type galaxies in the Virgo cluster (AMUSE-Virgo). This large program targets 100 early-type galaxies with…
Super-resolving distant galaxies with gravitational telescopes: Keck-LGSAO and Hubble imaging of the lens system SDSSJ0737+3216
P. J. Marshall, T. Treu, J. Melbourne +13
We combine high-resolution images in four optical/infra-red bands, obtained with the laser guide star adaptive optics system on the Keck Telescope and with the Hubble Space Telesco…
A Bayesian approach to strong lensing modelling of galaxy clusters
Eric Jullo, Jean-Paul Kneib, Marceau Limousin +3
In this paper, we describe a procedure for modelling strong lensing galaxy clusters with parametric methods, and to rank models quantitatively using the Bayesian evidence. We use a…
The All-wavelength Extended Groth Strip International Survey (AEGIS) Data Sets
M. Davis, P. Guhathakurta, N. Konidaris +53
In this the first of a series of Letters, we present a description of the panchromatic data sets that have been acquired in the Extended Groth Strip region of the sky. Our survey,…
A Strong-Lens Survey in AEGIS: the influence of large scale structure
L. A. Moustakas, P. J. Marshall, J. A. Newman +10
We report on the results of a visual search for galaxy-scale strong gravitational lenses over 650 arcmin^2 of HST/ACS imaging in the DEEP2-EGS field. In addition to a previously-kn…
Bayesian evidence as a tool for comparing datasets
Phil Marshall, Nutan Rajguru, Anze Slosar
We introduce a new conservative test for quantifying the consistency of two or more datasets. The test is based on the Bayesian answer to the question, ``How much more probable is…
Supernova / Acceleration Probe: A Satellite Experiment to Study the Nature of the Dark Energy
SNAP Collaboration, G. Aldering, W. Althouse +109
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's…
Bayesian joint analysis of cluster weak lensing and Sunyaev-Zel'dovich effect data
P. J. Marshall, M. P. Hobson, A. Slosar
As the quality of the available galaxy cluster data improves, the models fitted to these data might be expected to become increasingly complex. Here we present the Bayesian approac…
Cosmology from Cluster SZ and Weak Lensing Data
P. J. Marshall, K. Lancaster, M. P. Hobson +1
Weak gravitational lensing and the Sunyaev-Zel'dovich effect provide complementary information on the composition of clusters of galaxies. Preliminary results from cluster SZ obser…
Maximum-Entropy Reconstruction of the Distribution of Mass in Cluster MS1054-03 from Weak Lensing Data
P. J. Marshall
Weak gravitational lensing studies of clusters of galaxies provide complimentary information to that from X-ray data; the measured signal depends only on the cluster's projected ma…
