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…
Spatially-resolved HST Grism Spectroscopy of a Lensed Emission Line Galaxy at z~1
Brenda L. Frye, Mairead Hurley, David. V. Bowen +6
We take advantage of gravitational lensing amplification by Abell 1689 (z=0.187) to undertake the first space-based census of emission line galaxies (ELGs) in the field of a massiv…
A Brightest Cluster Galaxy with an Extremely Large Flat Core
Marc Postman, Tod R. Lauer, Megan Donahue +14
Hubble Space Telescope images of the galaxy cluster Abell 2261, obtained as part of the Cluster Lensing And Supernova survey with Hubble, show that the brightest galaxy in the clus…
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…
