A cold component and the complex velocity structure of DLA1331+170
R F Carswell, R A Jorgenson, A M Wolfe +1
[ABRIDGED] We examine the velocity structure in the gas associated with \ion{H}{1} in the damped Ly absorption system at redshift towards the QSO using 21c…
On the Analysis of DLA Kinematics
J. Xavier Prochaska, Arthur M. Wolfe
We discuss two mistreatments of damped Lya (DLA) kinematic analysis that were first performed by Haehnelt, Steinmetz, & Rauch (1998; hereafter HSR98) and have recently been repeate…
Cosmological concordance or chemical coincidence? Deuterated molecular hydrogen abundances at high redshift
J. Tumlinson, A. L. Malec, R. F. Carswell +8
We report two detections of deuterated molecular hydrogen (HD) in QSO absorption-line systems at . Toward J2123-0500, we find (HD) for a sub-DLA with me…
The nature of proximate damped Lyman alpha systems
Sara L. Ellison, J. Xavier Prochaska, Joseph Hennawi +5
We present high resolution echelle spectra of 7 proximate damped Lyman alpha (PDLA) systems whose relative velocity separation from the background quasar is Delta V < 3000 km/s. Co…
