Cosmochemistry, Cosmology and Fundamental Constants: High-Resolution Spectroscopy of Damped Lyman-Alpha Systems
R. Quast, D. Reimers, A. Smette +4
Spectroscopy of QSO absorption lines provides essential observational input for the study of nucleosynthesis and chemical evolution of galaxies at high redshift. But new observatio…
Clues to the origin of metals in the Ly-alpha forest
S. Lopez, S. D'odorico, S. L. Ellison +1
We analyze the z=2 Ly-alpha and CIV forest along two adjacent lines-of-sight at high S/N and spectral resolution to assess the question of the origin of metals in the intergalactic…
The CORALS Survey: A Review and Progress Report on The Search for Dust Obscured Quasar Absorption Line Systems
Sara L. Ellison, Max Pettini, Chris W. Churchill +6
We present a brief overview of the ongoing Complete Optical and Radio Absorption Line System (CORALS) survey. We review the results of our survey for z>2.2 damped Lyman alpha syste…
Disentangling microlensing and differential extinction in the double QSO HE0512-3329
O. Wucknitz, L. Wisotzki, S. Lopez +1
We present the first separate spectra of both components of the small-separation double QSO HE0512-3329 obtained with HST/STIS in the optical and near UV. The similarities especial…
