Spatially Resolved Emission of a High Redshift DLA Galaxy with the Keck/OSIRIS IFU
Regina A. Jorgenson, Arthur M. Wolfe
We present the first Keck/OSIRIS infrared IFU observations of a high redshift damped Lyman-alpha (DLA) galaxy detected in the line of sight to a background quasar. By utilizing the…
The Rapid Decline in Metallicity of Damped Ly-alpha Systems at z~5
Marc Rafelski, Marcel Neeleman, Michele Fumagalli +2
We present evidence that the cosmological mean metallicity of neutral atomic hydrogen gas shows a sudden decrease at z>4.7 down to <Z>=-2.03(+0.09-0.11), which is 6 sigma deviant f…
UVUDF: Ultraviolet Imaging of the Hubble Ultradeep Field with Wide-field Camera 3
Harry I. Teplitz, Marc Rafelski, Peter Kurczynski +23
We present an overview of a 90-orbit Hubble Space Telescope treasury program to obtain near ultraviolet imaging of the Hubble Ultra Deep Field using the Wide Field Camera 3 UVIS de…
The Fundamental Plane of Damped Lyman Alpha Systems
Marcel Neeleman, Arthur M. Wolfe, J. Xavier Prochaska +1
Using a sample of 100 H I - selected damped Lyman alpha (DLA) systems, observed with the High Resolution Echelle Spectrometer on the Keck I telescope, we present evidence that the…
