VizieR Online Data Catalog: XQ-100 survey neutral gas (Sanchez-Ramirez+, 2016)

Abstract

The XQ-100 survey is an ESO Large Program (ESO ID 189.A-0424, P.I. S. Lopez) which obtained X-shooter spectra of 100 3.5<z<4.7 QSOs in the period between 2012-02-10 and 2014-02-23. X-shooter is a triple-arm spectrograph which obtains moderate-resolution spectra with complete wavelength coverage from ~320-2500nm, permitting the simultaneous analysis of QSO absorption lines and emission features from the atmospheric cut-off to the near-IR. <P />Based on the results of the XQ-100 survey, we report the detection of 38 intervening DLAs identified towards 100 z>3.5 QSOs. This sample has been combined, after exhaustive checking for duplications and errors, with a literature sample of DLA surveys spanning the last ~20 years. <P />(2 data files). <P />
