Exploring the Thermal State of the Low-Density Intergalactic Medium at z=3 with an Ultra-High Signal-to-Noise QSO Spectrum
A. Rorai, G. D. Becker, M. G. Haehnelt +11
At low densities the standard ionisation history of the intergalactic medium (IGM) predicts a decreasing temperature of the IGM with decreasing density once hydrogen (and helium) r…
On the selection of damped Lyman alpha systems using MgII absorption at 2<z<4
T. A. M. Berg, S. L. Ellison, J. X. Prochaska +8
The XQ-100 survey provides optical and near infrared coverage of 36 blindly selected, intervening damped Lyman alpha systems (DLAs) at 2 < z < 4, simultaneously covering the MgII d…
Chemical abundances of damped Lyman alpha systems in the XQ-100 survey
T. A. M. Berg, S. L. Ellison, R. Sanchez-Ramirez +8
The XQ-100 survey has provided high signal-noise spectra of 100 redshift 3-4.5 quasars with the X-Shooter spectrograph. The metal abundances for 13 elements in the 41 damped Lyman…
Metals in the z~3 intergalactic medium: results from an ultra-high signal-to-noise ratio UVES quasar spectrum
V. D'Odorico, S. Cristiani, E. Pomante +13
In this work, we investigate the abundance and distribution of metals in the intergalactic medium (IGM) at through the analysis of an ultra-high sign…
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…
Nature and statistical properties of quasar associated absorption systems in the XQ-100 Legacy Survey
Serena Perrotta, Valentina D'Odorico, J. Xavier Prochaska +12
We statistically study the physical properties of a sample of narrow absorption line (NAL) systems looking for empirical evidences to distinguish between intrinsic and intervening…
