Dynamics of Galactic Disks and Mergers at z~1.6: Spatially Resolved Spectroscopy with Keck Laser Guide Star Adaptive Optics
Shelley A. Wright, James E. Larkin, David R. Law +3
We present 0.2" resolution near-infrared integral field spectroscopy of H-alpha emission from six star forming galaxies at z~1.6 (look-back time of ~9.6 Gyr). These observations we…
The Least Luminous Galaxy: Spectroscopy of the Milky Way Satellite Segue 1
Marla Geha, Beth Willman, Josh D. Simon +4
We present Keck/DEIMOS spectroscopy of Segue 1, an ultra-low luminosity (M_V = -1.5) Milky Way satellite companion. While the combined size and luminosity of Segue 1 are consistent…
Integral Field Spectroscopy of High-Redshift Star Forming Galaxies with Laser Guided Adaptive Optics: Evidence for Dispersion-Dominated Kinematics
David R. Law, Charles C. Steidel, Dawn K. Erb +4
We present early results from an ongoing study of the kinematic structure of star-forming galaxies at redshift z ~ 2 - 3 using integral-field spectroscopy of rest-frame optical neb…
Morphologies of Galaxies in and around a Protocluster at z=2.300
Annika H. G. Peter, Alice E. Shapley, David R. Law +4
We present results from the first robust investigation of galaxy morphology as a function of environment at z>1.5. Our study is motivated by the fact that star-forming galaxies con…
Integral Field Spectroscopy of a Candidate Disk Galaxy at z~1.5 using Laser Guide Star Adaptive Optics
S. A. Wright, J. E. Larkin, M. Barczys +8
We present 0.1" resolution near-infrared integral field spectroscopy of Halpha in a z=1.4781 star forming galaxy, Q2343-BM133. These observations were obtained with OSIRIS (OH Supp…
The Physical Nature of Rest-UV Galaxy Morphology During the Peak Epoch of Galaxy Formation
David R. Law, Charles C. Steidel, Dawn K. Erb +5
Motivated by the irregular and little-understood morphologies of z ~ 2 - 3 galaxies, we use non-parametric coefficents to quantify the morphologies of 216 galaxies which have been…
