Broad absorption line disappearance/emergence in multiple ions in a weak emission-line quasar
Weimin Yi, M. Vivek, W. N. Brandt +9
We report the discovery of disappearance of Mg ii, Al iii, C iv, and Si iv broad absorption lines (BALs) at the same velocity, accompanied by a new Civ BAL emerging at a higher vel…
X-ray and multi-epoch optical/UV investigations of BAL to non-BAL quasar transformations
Sameer, W. N. Brandt, S. Anderson +10
We report on an X-ray and optical/UV study of eight Broad Absorption Line (BAL) to non-BAL transforming quasars at 1.7-2.2 over 0.29-4.95 rest-frame years with at lea…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
Optical variability in IBL S5 0716+714 during the 2013-2015 outburst
Navpreet Kaur, Kiran S. Baliyan, S. Chandra +2
With an aim to explore optical variability at diverse timescales in BL Lac source S5 0716+714, it was observed for 46 nights during 2013 January 14 to 2015 June 01 when it underwen…
