The Galaxy Population In Voids: Are All Voids The Same?
Saeed Tavasoli, Hadi Rahmani, Habib G. Khosroshahi +2
The influence of under-dense environments on the formation and evolution of galaxies is studied by analysing the photometric properties of ~200 galaxies residing in voids, taken fr…
The UVES Large Program for testing fundamental physics - III. Constraints on the fine-structure constant from 3 telescopes
T. M. Evans, M. T. Murphy, J. B. Whitmore +10
Large statistical samples of quasar spectra have previously indicated possible cosmological variations in the fine-structure constant, . A smaller sample of higher signal-to-noi…
The dust, nebular emission and dependence on QSO radio properties of the associated Mg II absorption line systems
Pushpa Khare, Daniel Vanden Berk, Hadi Rahmani +1
We studied dust reddening and [O II] emission in 1730 Mg II associated absorption systems (AAS; relative velocity with respect to QSOs, < 3000 km/s; in units of velocity of light,…
Molecular hydrogen from z = 0.0963 DLA towards the QSO J1619+3342
Raghunathan Srianand, Hadi Rahmani, Sowgat Muzahid +1
We report the detection of H2 in a zabs= 0.0963 Damped Lyman-α (DLA) system towards zem = 0.4716 QSO J1619+3342. This DLA has log N(H I) = 20.55 (0.10), 18.13 < log N(H2) < 18.40,…
A study of low-metallicity DLAs at high redshift and C II* as a probe of their physical conditions
R. Dutta, R. Srianand, H. Rahmani +3
We present a detailed high spectral resolution (R 40000) study of five high-z damped Lyman systems (DLAs) and one sub-DLA detected along four QSO sightlines. Four of the…
The star-formation history of mass-selected galaxies from the VIDEO survey
Jonathan T. L. Zwart, Matt J. Jarvis, Roger P. Deane +5
We measure star-formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VIDEO survey by stacking 1.4-GHz Very Large Array data. We split the sample, which…
