The HiZELS/UKIRT large area survey for bright Lyman-alpha emitters at z~9
David Sobral, Philip Best, Jim Geach +7
We present the largest area survey to date (1.4 deg2) for Lyman-alpha emitters (LAEs) at z~9, as part of the Hi-z Emission Line Survey (HiZELS). The survey, which primarily targets…
Optical and near-IR spectroscopy of candidate red galaxies in two z~2.5 proto-clusters
Michelle Doherty, Masayuki Tanaka, Carlos De Breuck +9
We present a spectroscopic campaign to follow-up red colour-selected candidate massive galaxies in two high redshift proto-clusters surrounding radio galaxies. We observed a total…
Witnessing the assembly at z=1.6 of a galaxy cluster (GMASS ultradeep spectroscopy of galaxies at z~2 - V)
J. Kurk, A. Cimatti, G. Zamorani +12
We present a study of a galaxy overdensity at z=1.6, Cl 0332-2742, uncovered in the Galaxy Mass Assembly ultra-deep Spectroscopic Survey (GMASS). We conservatively estimate the ove…
Dynamical masses of early-type galaxies at z~2: Are they truly superdense?
Michele Cappellari, S. di Serego Alighieri, A. Cimatti +11
We measured stellar velocity dispersions sigma and dynamical masses of 9 massive (M~10^11 Msun) early-type galaxies (ETG) from the GMASS sample at redshift 1.4<z<2.0. The sigma are…
GMASS ultradeep spectroscopy of galaxies at z ~ 2. IV. The variety of dust populations
S. Noll, D. Pierini, A. Cimatti +14
The properties of dust attenuation at rest-frame UV wavelengths are inferred from very high-quality FORS2 spectra of 78 galaxies from the GMASS survey at 1<z<2.5. These objects com…
The SINS survey: modeling the dynamics of z~2 galaxies and the high-z Tully-Fisher relation
G. Cresci, E. K. S. Hicks, R. Genzel +23
We present the modeling of SINFONI integral field dynamics of 18 star forming galaxies at z ~ 2 from Halpha line emission. The galaxies are selected from the larger sample of the S…
