Average Extinction Curves and Relative Abundances for QSO Absorption Line Systems at 1 <= z_abs < 2
Donald G. York, Pushpa Khare, Daniel Vanden Berk +21
We have studied a sample of 809 Mg II absorption systems with 1.0 < z_abs < 1.86 in the spectra of SDSS QSOs, with the aim of understanding the nature and abundance of the dust and…

Evidence for the presence of dust in intervening QSO absorbers from the Sloan Digital Sky Survey
P. Khare, D. G. York, D. Vanden Berk +17
We find evidence for dust in the intervening QSO absorbers from the spectra of QSOs in the Sloan Digital Sky Survey Data Release 1. No evidence is found for the 2175 A feature whic…
