Recurrent Multi-year Mg II BAL Variability in SDSS J1333+0012
M. Vivek, P. Aromal, R. Srianand +3
We present a long-term spectroscopic study of Broad Absorption Line (BAL) variability in the quasar J1333+0012 (\zem = 0.9197) using an extensive multi-epoch dataset spanning nearl…
Importance and Science Outcomes from the first XSPECT/XPoSat Workshop
Anuj Nandi, Rwitika Chatterjee, V. P. Shyam Prakash +49
This paper summarizes the science outcomes of the first Workshop on Data Analysis using observations from the XSPECT payload onboard the XPoSat, which brought together early-career…
Transient LoBALs at high velocities: A Case of Extreme Broad Absorption Line Variability in J115636.82+085628.9
P. Aromal, R. Srianand, S. C. Gallagher +2
We present a multi-epoch spectroscopic study of the broad absorption line (BAL) quasar J115636.82+085628.9 (z(em) = 2.1077), based on five spectra spanning nearly two decades in th…
Time variability of ultra-fast BAL outflows using SALT: C IV absorption depth based analysis
P. Aromal, R. Srianand, P. Petitjean
We probe the small-scale absorption line variability using absorption depth based analysis of a sample of 64 ultra-fast outflow (UFO) C IV broad absorption line (BAL) quasars monit…
Time variability of ultra-fast BAL outflows using SALT: C IV equivalent width analysis
P. Aromal, R. Srianand, P. Petitjean
We study the time variability (over 7.3 yrs) of ultra-fast outflows (UFOs) detected in a sample of 64 C IV broad absorption line (BAL) quasars (with 80 distinct BAL components…
Coordinated time variability of multi-phase ultra-fast outflows in J132216.25+052446.3
P. Aromal, R. Srianand, P. Petitjean
We present a time variability analysis of broad absorption lines (BAL; spread over the velocity range of 5800-29000 km/s) seen in the spectrum of J132216.25+052446.3 (z(em)= 2.0480…
Correlated time variability of multi-component high velocity outflows in J162122.54+075808.4
P. Aromal, R. Srianand, P. Petitjean
We present a detailed analysis of time variability of two distinct C IV broad absorption line (BAL) components seen in the spectrum of J162122.54+075808.4 ( = 2.1394) using…
