Seven broad absorption line quasars with excess broad band absorption near 2250 Å
Shaohua Zhang, Jian Ge, Peng Jiang +6
We report the discovery of excess broad band absorption near 2250 A (EBBA) in the spectra of seven broad absorption line (BAL) quasars. By comparing with the statistical results fr…
Galactic nebular lines in the fiber spectra of background QSOs: Reaching a hundred QSO-galaxy pairs with spectroscopic and photometric measurements
Lorrie Straka, Pasquier Noterdaeme, Raghunathan Srianand +6
We present photometric and spectroscopic measurements of 53 QSO-galaxy pairs from the Sloan Digital Sky Survey, where nebular emission lines from a 0<z<0.84 foreground galaxy are d…
Mock Quasar-Lyman-α Forest Data-sets for the SDSS-III Baryon Oscillation Spectroscopic Survey
Julian E. Bautista, Stephen Bailey, Andreu Font-Ribera +15
We describe mock data-sets generated to simulate the high-redshift quasar sample in Data Release 11 (DR11) of the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS). The mock…
Cosmological implications of baryon acoustic oscillation (BAO) measurements
Éric Aubourg, Stephen Bailey, Julian E. Bautista +90
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…
The High A(V) Quasar Survey: Reddened quasi-stellar objects selected from optical/near-infrared photometry - II
J. -K. Krogager, S. Geier, J. P. U. Fynbo +9
Quasi-stellar objects (QSOs) whose spectral energy distributions (SEDs) are reddened by dust either in their host galaxies or in intervening absorber galaxies are to a large degree…
The mysterious optical afterglow spectrum of GRB140506A at z=0.889
J. P. U. Fynbo, T. Krühler, K. Leighly +40
Context. Gamma-ray burst (GRBs) afterglows probe sightlines to star-forming regions in distant star-forming galaxies. Here we present a study of the peculiar afterglow spectrum of…
