MIFAL: fully automated Multiple-Image Finder ALgorithm for strong-lens modelling -- proof of concept
Mauricio Carrasco, Adi Zitrin, Gregor Seidel
We outline a simple procedure designed for \emph{automatically} finding sets of multiple images in strong lensing (SL) clusters. We show that by combining (a) an arc-finding (or so…
EasyCritics II. Testing its efficiency: new gravitational lens candidates in CFHTLenS
M. Carrasco, S. Stapelberg, M. Maturi +3
We report the results of , a fully automated algorithm for the efficient search of strong-lensing (SL) regions in wide-field surveys, applied to the Canada-France-Hawa…
EasyCritics I: Efficient detection of strongly-lensing galaxy groups and clusters in wide-field surveys
Sebastian Stapelberg, Mauricio Carrasco, Matteo Maturi
We present EasyCritics, an algorithm to detect strongly-lensing groups and clusters in wide-field surveys without relying on a direct recognition of arcs. EasyCritics assumes that…
Hubble Space Telescope Combined Strong and Weak Lensing Analysis of the CLASH Sample: Mass and Magnification Models and Systematic Uncertainties
Adi Zitrin, Agnese Fabris, Julian Merten +23
We present results from a comprehensive lensing analysis in HST data, of the complete CLASH cluster sample. We identify new multiple-images previously undiscovered allowing improve…
CLASH: The Concentration-Mass Relation of Galaxy Clusters
J. Merten, M. Meneghetti, M. Postman +38
We present a new determination of the concentration-mass relation for galaxy clusters based on our comprehensive lensing analysis of 19 X-ray selected galaxy clusters from the Clus…
CLASH: A Census of Magnified Star-Forming Galaxies at z ~ 6-8
L. D. Bradley, A. Zitrin, D. Coe +34
We utilize 16 band Hubble Space Telescope (HST) observations of 18 lensing clusters obtained as part of the Cluster Lensing And Supernova survey with Hubble (CLASH) Multi-Cycle Tre…
Strong Lensing Analysis of PLCK G004.519.5, a Planck-Discovered Cluster Hosting a Radio Relic at
Cristóbal Sifón, Felipe Menanteau, John P. Hughes +2
The recent discovery of a large number of galaxy clusters using the Sunyaev-Zel'dovich (SZ) effect has opened a new era on the study of the most massive clusters in the Universe. M…
CLASH: The enhanced lensing efficiency of the highly elongated merging cluster MACS J0416.1-2403
A. Zitrin, M. Meneghetti, K. Umetsu +21
We perform a strong-lensing analysis of the merging galaxy cluster MACS J0416.1-2403 (M0416; z=0.42) in recent CLASH/HST observations. We identify 70 new multiple images and candid…
CLASH: Three Strongly Lensed Images of a Candidate z ~ 11 Galaxy
Dan Coe, Adi Zitrin, Mauricio Carrasco +20
We present a candidate for the most distant galaxy known to date with a photometric redshift z = 10.7 +0.6 / -0.4 (95% confidence limits; with z < 9.5 galaxies of known types ruled…
A Census of Star-Forming Galaxies in the z~9-10 Universe based on HST+Spitzer Observations Over 19 CLASH clusters: Three Candidate z~9-10 Galaxies and Improved Constraints on the Star Formation Rate Density at z~9
R. Bouwens, L. Bradley, A. Zitrin +34
We utilise a two-color Lyman-Break selection criterion to search for z~9-10 galaxies over the first 19 clusters in the CLASH program. A systematic search yields three z~9-10 candid…
A highly magnified candidate for a young galaxy seen when the Universe was 500 Myrs old
Wei Zheng, Marc Postman, Adi Zitrin +33
The early Universe at redshift z\sim6-11 marks the reionization of the intergalactic medium, following the formation of the first generation of stars. However, those young galaxies…
CLASH: Mass Distribution in and around MACS J1206.2-0847 from a Full Cluster Lensing Analysis
Keiichi Umetsu, Elinor Medezinski, Mario Nonino +45
We derive an accurate mass distribution of the galaxy cluster MACS J1206.2-0847 (z=0.439) from a combined weak-lensing distortion, magnification, and strong-lensing analysis of wid…
CLASH: Precise New Constraints on the Mass Profile of Abell 2261
Dan Coe, Keiichi Umetsu, Adi Zitrin +43
We precisely constrain the inner mass profile of Abell 2261 (z=0.225) for the first time and determine this cluster is not "over-concentrated" as found previously, implying a forma…
A bright, spatially extended lensed galaxy at z = 1.7 behind the cluster RCS2 032727-132623
Eva Wuyts, L. Felipe Barrientos, Michael D. Gladders +7
We present the discovery of an extremely bright and extended lensed source from the second Red Sequence Cluster Survey (RCS2). RCSGA 032727-132609 is spectroscopically confirmed as…
