The Hawk-I UDS and GOODS Survey (HUGS): Survey design and deep K-band number counts
A. Fontana, J. S. Dunlop, D. Paris +40
We present the results of a new, ultra-deep, near-infrared imaging survey executed with the Hawk-I imager at the ESO VLT, of which we make all the data public. This survey, named H…
The UV Continuum of z > 1 Star-forming Galaxies in the Hubble Ultraviolet UltraDeep Field
Peter Kurczynski, Eric Gawiser, Marc Rafelski +11
We estimate the UV continuum slope, beta, for 923 galaxies in the range 1 < z < 8 in the Hubble Ultradeep Field (HUDF). These data include 460 galaxies at 1 < z < 2 down to an abso…
The Wavelength Dependence of High-Redshift Galaxy Structure in the Rest-Frame Ultraviolet
Nicholas A. Bond, Jonathan P. Gardner, Duilia F. de Mello +8
We present the rest-frame UV wavelength dependence of the Petrosian-like half-light radius (), and the concentration parameter for a sample of 198 star-forming galaxies at…
Star-forming blue ETGs in two newly discovered galaxy overdensities in the HUDF at z=1.84 and 1.9: unveiling the progenitors of passive ETGs in cluster cores
Simona Mei, Claudia Scarlata, Laura Pentericci +15
We present the discovery of two galaxy overdensities in the Hubble Space Telescope UDF: a proto-cluster, HUDFJ0332.4-2746.6 at , and a group, HUDFJ0332.5-2747.3…
Physical Properties of Emission-Line Galaxies at z ~ 2 from Near-Infrared Spectroscopy with Magellan FIRE
Daniel Masters, Patrick McCarthy, Brian Siana +16
We present results from near-infrared spectroscopy of 26 emission-line galaxies at z ~ 2 obtained with the FIRE spectrometer on the Magellan Baade telescope. The sample was selecte…
Spectroscopic observation of Ly emitters at z~7.7 and implications on re-ionization
A. L. Faisst, P. Capak, C. M. Carollo +2
We present spectroscopic follow-up observations on two bright Ly emitter (LAE) candidates originally found by Krug et al. (2012) at a redshift of z~7.7 using the Multi-Object Sp…
