Brightest X-ray clusters of galaxies in the CFHTLS wide fields: Catalog and optical mass estimator
M. Mirkazemi, A. Finoguenov, M. J. Pereira +13
The CFHTLS presents a unique data set for weak lensing studies, having high quality imaging and deep multi-band photometry. We have initiated an XMM-CFHTLS project to provide X-ray…
New Constraints on the Faint-end of the UV Luminosity Function at z~7-8 using the Gravitational Lensing of the Hubble Frontier Fields Cluster A2744
Hakim Atek, Johan Richard, Jean-Paul Kneib +8
Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant Universe far beyond the…
CFHTLenS: Weak lensing calibrated scaling relations for low mass clusters of galaxies
K. Kettula, S. Giodini, E. van Uitert +24
We present weak lensing and X-ray analysis of 12 low mass clusters from the CFHTLenS and XMM-CFHTLS surveys. We combine these systems with high-mass systems from CCCP and low-mass…
Hubble Frontier Fields : A High-Precision Strong-Lensing Mass Model of the Massive Galaxy Cluster Abell 2744 using 180 Multiple Images
Mathilde Jauzac, Johan Richard, Eric Jullo +11
We present a high-precision mass model of galaxy cluster Abell 2744, based on a strong-gravitational-lensing analysis of the \emph{Hubble Space Telescope Frontier Fields} (HFF) ima…
Molecular gas content in strongly-lensed z~1.5-3 star-forming galaxies with low IR luminosities
M. Dessauges-Zavadsky, M. Zamojski, D. Schaerer +10
To extend the molecular gas measurements to typical star-forming galaxies (SFGs) with SFR < 40 Msun yr^{-1} and M* < 2.5x10^{10} Msun at z~1.5-3, we have observed CO emission with…
LoCuSS: The Near-Infrared Luminosity and Weak-Lensing Mass Scaling Relation of Galaxy Clusters
Sarah L. Mulroy, Graham P. Smith, Chris P. Haines +7
We present the first scaling relation between weak-lensing galaxy cluster mass, , and near-infrared luminosity, . Our results are based on 17 clusters observed with wi…
