Discovery of a cool, metal-rich gas reservoir in the outskirts of z ~ 0.5 clusters
Sapna Mishra, Sowgat Muzahid
We built the first-ever statistically significant sample of ~ 80,000 background quasar - foreground cluster pairs to study the cool, metal-rich gas in the outskirts (> R500) of z ~…
A Search for Blazar Activity in Broad-Absorption-Line Quasars
Sapna Mishra, Gopal-Krishna, Hum Chand +3
Our recently reported lack of Intra-Night Optical Variability (INOV) among Broad-Absorption-Line (BAL) quasars exhibiting some blazar-like radio properties, either questions polar…
Appearance vs Disappearance of broad absorption line troughs in quasars
Sapna Mishra, M. Vivek, Hum Chand +1
We present a new set of 84 Broad absorption line (BAL) quasars ( 1.7 \zem 4.4) exhibiting an appearance of \civ BAL troughs over 0.34.8 rest-frame years by comparing the…
Are there broad absorption-line blazars?
Sapna Mishra, Gopal-Krishna, Hum Chand +2
We report the first systematic search for blazars among broad-absorption-line (BAL) quasars. This is based on our intranight optical monitoring of a well-defined sample of 10 candi…
