Schrabback, Tim, Hartlap, Jan, Joachimi, Benjamin, Kilbinger, Martin, Simon, Patrick, Benabed, Karim, ...
We present a tomographic cosmological weak lensing analysis of the HST COSMOS Survey. Applying our lensing-optimized data reduction, principal component interpolation for the ACS PSF, and improved...
Morganson, Eric, Marshall, Phil, Treu, Tommaso, Schrabback, Tim, Blandford, Roger D.
We have searched 4.5 square degrees of archival HST/ACS images for cosmic strings, identifying close pairs of similar, faint galaxies and selecting groups whose alignment is consistent with...
An Atlas of Predicted Exotic Gravitational Lenses (2009)
De Xivry, Gilles Orban, Marshall, Phil
Wide-field optical imaging surveys will contain tens of thousands of new strong gravitational lenses. Some of these will have new and unusual image configurations, and so will enable new...
Strong gravitational lensing probes of the particle nature of dark matter (2009)
Moustakas, Leonidas A., Abazajian, Kevork, Benson, Andrew, Bolton, Adam S., Bullock, James S., Chen, Jacqueline, ...
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these candidates may have...
A Strong-Lens Survey in AEGIS: the influence of large scale structure (2008)
Moustakas, Leonidas A., Marshall, Phil, Newman, Jeffrey A., Coil, Alison L., Cooper, Michael C., Davis, Marc, ...
Dark Matter and Baryons in the Most X-ray Luminous and Merging Galaxy Cluster RX J1347.5-1145 (2007)
Bradač, Maruša, Schrabback, Tim, Erben, Thomas, McCourt, Michael, Million, Evan, Mantz, Adam, ...
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 formation and...
AMUSE-Virgo I. Super-massive black holes in low-mass spheroids (2007)
Gallo, Elena, Treu, Tommaso, Jacob, Jeremy, Woo, Jong-Hak, Marshall, Phil, Antonucci, Robert
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 the Advanced CCD...
Gasparini, Maria Alice, Marshall, Phil, Treu, Tommaso, Morganson, Eric, Dubath, Florian
We use current theoretical estimates for the density of long cosmic strings to predict the number of strong gravitational lensing events in astronomical imaging surveys as a function of angular...
A Bayesian approach to strong lensing modelling of galaxy clusters (2007)
Jullo, Eric, Kneib, Jean-Paul, Limousin, Marceau, Elíasdóttir, Árdis, Marshall, Phil, Verdugo, Tomas
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 publicly available...
Analytic models of plausible gravitational lens potentials (2007)
Baltz, Edward A., Marshall, Phil, Oguri, Masamune
Gravitational lenses on galaxy scales are plausibly modelled as having ellipsoidal symmetry and a universal dark matter density profile, with a Sersic profile to describe the distribution of baryonic...
Bradac, Marusa, Clowe, Douglas, Gonzalez, Anthony H., Marshall, Phil, Forman, William, Jones, Christine, ...
The galaxy cluster 1E0657-56 (z = 0.296) is remarkably well-suited for addressing outstanding issues in both galaxy evolution and fundamental physics. We present a reconstruction of the mass...
Physical component analysis of galaxy cluster weak gravitational lensing data (2005)
We present a novel approach for reconstructing the projected mass distribution of clusters of galaxies from sparse and noisy weak gravitational lensing shear data. The reconstructions are regularised...
The SNAP Strong Lens Survey (2005)
Marshall, Phil, Blandford, Roger, Sako, Masao
Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical...
Bayesian evidence as a tool for comparing datasets (2004)
Marshall, Phil, Rajguru, Nutan, Slosar, Anze
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 it that all my data...
Very Small Array observations of the Sunyaev-Zel'dovich effect in nearby galaxy clusters (2004)
Lancaster, Katy, Genova-Santos, Ricardo, Falcon, Nelson, Grainge, Keith, Gutierrez, Carlos, Kneissl, Ruediger, ...
We present VSA observations (~34GHz) on scales ~20 arcmin towards a complete, X-ray-flux-limited sample of seven clusters at redshift z
Abstract The SNAP Strong Lens Survey (2004)
Phil Marshall, Roger Bl, Masao Sako
Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical...
Kneib, Jean-Paul, Hudelot, Patrick, Ellis, Richard S., Treu, Tommaso, Smith, Graham P., Marshall, Phil, ...
(abridged) We present a comprehensive lensing analysis of the rich cluster Cl0024+1654 based on panoramic sparse-sampled imaging conducted with HST. We demonstrate an ability to detect reliably weak...
