Finding the brightest cosmic beacons in the Southern Hemisphere
Calderone G., Boutsia K., Cristiani S. +6
The study of absorptions along the lines of sight to bright high- QSOs is an invaluable cosmological tool that provides a wealth of information on the inter-/circum-galactic med…
Sub-damped Lyman alpha systems in the XQ-100 survey I -- Identification and contribution to the cosmological HI budget
Trystyn A. M. Berg, Sara L. Ellison, Ruben Sanchez-Ramirez +7
Sub-damped Lyman alpha systems (subDLAs; HI column densities of 19.0<=logN(HI)<20.3) are rarely included in the cosmic HI census performed at redshifts z>=1.5, yet are expected to…
The Evolution of O I over 3.2 < z < 6.5: Reionization of the Circumgalactic Medium
George D. Becker, Max Pettini, Marc Rafelski +11
We present a survey for metal absorption systems traced by neutral oxygen over . Our survey uses Keck/ESI and VLT/X-Shooter spectra of 199 QSOs with redshifts up to…
Ionising the Intergalactic Medium by Star Clusters: The first empirical evidence
E. Vanzella, G. B. Caminha, F. Calura +14
We present a VLT/X-Shooter spectroscopy of the Lyman continuum (LyC) emitting galaxy 'Ion2' at z=3.2121 and compare it to that of the recently discovered strongly lensed LyC-emitte…
