Parsec-scale structures and diffuse bands in a translucent interstellar medium at z 0.079
R. Srianand, N. Gupta, H. Rahmani +3
We present a detailed study of the QSO-galaxy pair [SDSS J163956.35+112758.7 (zq = 0.993) and SDSS J163956.38+112802.1 (zg = 0.079)] based on observations carried out using the Gia…

Constraining the variation of fundamental constants at z ~ 1.3 using 21-cm absorbers
H. Rahmani, R. Srianand, N. Gupta +3
We present high resolution optical spectra obtained with the Ultraviolet and Visual Echelle Spectrograph (UVES) at the Very Large Telescope (VLT) and 21-cm absorption spectra obtai…

Metallicities, dust and molecular content of a QSO-Damped Lyman-α system reaching log N (H i) = 22: An analog to GRB-DLAs
R. Guimarães, P. Noterdaeme, P. Petitjean +4
We present the elemental abundance and H2 content measurements of a Damped Lyman-α (DLA) system with an extremely large H i column density, log N(H i) (cm-2) = 22.0+/-0.10, at zabs…
