An ASKAP survey for HI absorption towards dust-obscured quasars
M. Glowacki, J. R. Allison, V. A. Moss +11
Obscuration of quasars by accreted gas and dust, or dusty intervening galaxies, can cause active galactic nuclei (AGN) to be missed in optically-selected surveys. Radio observation…
XQ-100: A legacy survey of one hundred 3.5 < z < 4.5 quasars observed with VLT/XSHOOTER
S. Lopez, V. D'Odorico, S. L. Ellison +23
We describe the execution and data reduction of the European Southern Observatory Large Programme "Quasars and their absorption lines: a legacy survey of the high-redshift universe…
The evolution of neutral gas in damped Lyman systems from the XQ-100 survey
R. Sánchez-Ramírez, S. L. Ellison, J. X. Prochaska +10
We present a sample of 38 intervening Damped Lyman (DLA) systems identified towards 100 quasars, observed during the XQ-100 survey. The XQ-100 DLA sample is combined wi…
The Giant Gemini GMOS survey of z>4.4 quasars - I. Measuring the mean free path across cosmic time
Gábor Worseck, J. Xavier Prochaska, John M. O'Meara +7
We have obtained spectra of 163 quasars at with the Gemini Multi Object Spectrometers on the Gemini North and South telescopes, the largest publicly available s…
Galaxy counterparts of intervening high-z sub-DLAs/DLAs and MgII absorbers towards gamma-ray bursts
S. Schulze, J. P. U. Fynbo, B. Milvang-Jensen +19
We present the first search for galaxy counterparts of intervening high-z (2<z< 3.6) sub-DLAs and DLAs towards GRBs. Our final sample comprises of five intervening sub-DLAs and DLA…
New limit on a varying proton-to-electron mass ratio from high-resolution optical quasar spectra
Adrian L. Malec, Ruth Buning, Michael T. Murphy +7
Molecular transitions recently discovered at redshift z_abs=2.059 toward the bright background quasar J2123-0050 are analysed to limit cosmological variation in the proton-to-elect…
