QSO Selection and Photometric Redshifts with Neural Networks
Ch. Yeche, P. Petitjean, J. Rich +9
Baryonic Acoustic Oscillations (BAO) and their effects on the matter power spectrum can be studied by using the Lyman-alpha absorption signature of the matter density field along q…

21-cm absorbers at intermediate redshifts
N. Gupta, R. Srianand, P. Petitjean +2
Damped Lyman-alpha systems (DLAs) seen in the spectra of high-z QSOs allow us to probe the physical conditions in protogalaxies. Our understanding of physical conditions in DLAs at…

Detecting cold gas at intermediate redshifts: GMRT survey using Mg II systems
Neeraj Gupta, R. Srianand, P. Petitjean +3
Intervening HI 21-cm absorption systems at z > 1.0 are very rare and only 4 confirmed detections have been reported in the literature. Despite their scarcity, they provide interest…
