Influence of the jet opening angle on the derived kinematical parameters of blazar jets having uniform and stratified bulk motion
Gopal-Krishna, Samir Dhurde, Pronoy Sircar +1
We present analytical modelling of conical relativistic jets, in order to evaluate the role of the jet opening angle on certain key parameters that are inferred from VLBI radio obs…
Effects of Jet Opening Angle and Velocity Structure on Blazar Parameters
Paul J. Wiita, Gopal-Krishna, Samir Dhurde +1
We had earlier shown that for a constant velocity jet the discrepancy between the low speeds indicated by VLBI knot motions and the high Doppler factors inferred from emission of T…
Further evidence for intra-night optical variability of radio-quiet quasars
A. Goyal, Gopal-Krishna, Ram Sagar +2
Although well established for BL Lac objects and radio-loud quasars, the occurrence of intra-night optical variability (INOV) in radio-quiet quasars is still debated, primarily sin…
