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 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…
The Brightest of Reionizing Galaxies Survey: Constraints on the Bright End of the z~8 Luminosity Function
L. D. Bradley, M. Trenti, P. A. Oesch +6
We report the discovery of 33 Lyman break galaxy (LBG) candidates at z~8 detected in Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) imaging as part of the Brightest of Rei…
