Incidence of HI 21-cm absorption in strong FeII systems at $0.5 < z < 1.5$

R. Dutta, R. Srianand, N. Gupta +5

We present the results from our search for HI 21-cm absorption in a sample of 16 strong FeII systems ( $W_{r}$ (MgII $λ 2796$ ) $\geq 1.0$ Å and $W_{r}$ (FeII $λ 2600$ )…

The Ly $α$ emission from high- $z$ galaxies hosting strong Damped Ly $α$ systems

Ravi Joshi, Raghunathan Srianand, Pasquier Noterdaeme +1

We study the average Ly $α$ emission associated with high- $z$ strong (log $N$ (H I) $\geq$ 21) damped Ly $α$ systems (DLAs). We report Ly $α$ luminosities ( $L_{Ly α}$ ) for the full a…

Intranight Optical Variability of Radio-Quiet Weak Emission Line Quasars-IV

Parveen Kumar, Hum Chand, Gopal-Krishna

We report an extension of our program to search for radio-quiet BL Lac candidates using intra-night optical variability (INOV) as a probe. The present INOV observations cover a wel…
