The Keck+Magellan Survey for Lyman Limit Absorption III: Sample Definition and Column Density Measurements
J. Xavier Prochaska, John M. O'Meara, Michele Fumagalli +2
We present an absorption-line survey of optically thick gas clouds -- Lyman Limit Systems (LLSs) -- observed at high dispersion with spectrometers on the Keck and Magellan telescop…
The Neutral Hydrogen Cosmological Mass Density at z=5
Neil H. M. Crighton, Michael T. Murphy, J. Xavier Prochaska +8
We present the largest homogeneous survey of damped Lyman- systems (DLAs) using the spectra of 163 QSOs that comprise the Giant Gemini GMOS (GGG) survey. With this surve…
