Galaxy Mergers at z>1 in the HUDF: Evidence for a Peak in the Major Merger Rate of Massive Galaxies
R. E. Ryan, S. H. Cohen, R. A. Windhorst +1
We present a measurement of the galaxy merger fraction and number density from observations in the Hubble Ultra Deep Field for 0.5<z<2.5. We fit the combination of broadband data a…
Surface Brightness Profiles of Composite Images of Compact Galaxies at z~4-6 in the HUDF
N. P. Hathi, R. A. Jansen, R. A. Windhorst +4
The Hubble Ultra Deep Field (HUDF) contains a significant number of B, V and i'-band dropout objects, many of which were recently confirmed to be young star-forming galaxies at z~4…
The Galaxy Luminosity Function at z~1 in the HUDF: Probing the Dwarf Population
R. E. Ryan, N. P. Hathi, S. H. Cohen +10
We present a catalog of spectro-photometric redshifts for 1308 galaxies from the GRism ACS Program for Extragalactic Science (GRAPES) observations with the Hubble Space Telescope.…
