Radio Follow-Up Observations of a Weak-Line Quasar Exhibiting Remarkable X-ray Variability
Ayushi Chhipa, M. Vivek, Nayana A. J. +6
SDSSJ1539+3954 (), a radio-quiet weak-line quasar (WLQ), exhibited exceptional X-ray variability in 20192020, with its X-ray flux increasing by over 20 times fro…
Probing the Low Radio Frequency Emission in PG Quasars with the uGMRT -- II
Sanna Gulati, Silpa Sasikumar, Preeti Kharb +3
We present results from uGMRT 685 MHz observations of 87 QSOs belonging to the Palomar Green (PG) quasar sample with . Radio emission is detected in all sources except for 3…
Connection between steep radio spectral slopes and dust extinction in QSOs: evidence for outflow-driven shocks in dusty QSO
V. A. Fawcett, C. M. Harrison, D. M. Alexander +9
Recent studies have found a striking positive correlation between the amount of dust obscuration and enhanced radio emission in quasi-stellar objects (QSOs). However, what causes t…
Investigating Differences in the Palomar-Green Blazar Population Using Polarization
Janhavi Baghel, P. Kharb, T. Hovatta +5
We present polarization images with the Karl G. Jansky Very Large Array (VLA) in A and B-array configurations at 6 GHz of 7 radio-loud (RL) quasars and 8 BL Lac objects belonging t…
