First Results from Z-FOURGE: Discovery of a Candidate Cluster at z = 2.2 in COSMOS
Lee R. Spitler, Ivo Labbé, Karl Glazebrook +13
We report the first results from the Z-FOURGE survey: the discovery of a candidate galaxy cluster at z = 2.2 consisting of two compact overdensities with red galaxies detected at >…
Lyman alpha Luminosity Functions at Redshift z = 4.5
Zhen-Ya Zheng, Steven L. Finkelstein, Keely Finkelstein +7
We present a spectroscopically confirmed sample of Lyman alpha emitting galaxies (LAEs) at z ~ 4.5 in the Extended Chandra Deep Field South (ECDFS), which we combine with a sample…
Predicting the Merger Fraction of Lyman alpha Emitters from Redshift z~3 to z~7
Vithal Tilvi, Evan Scannapieco, Sangeeta Malhotra +1
Rapid mass assembly, likely from mergers or smooth accretion, has been predicted to play a vital role in star-formation in high-redshift Lyman-alpha (Lya) emitters. Here we predict…
Searching for z~7.7 Lyman Alpha Emitters in the COSMOS Field with NEWFIRM
Hannah Krug, Sylvain Veilleux, Vithal Tilvi +8
The study of Ly-alpha emission in the high-redshift universe is a useful probe of the epoch of reionization, as the Ly-alpha line should be attenuated by the intergalactic medium (…
