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…
