First uGMRT Constraints on Rotation Measure in the Radio-Quiet Seyfert Galaxy NGC 4235
Salmoli Ghosh, Preeti Kharb, Janhavi Baghel
We present a multi-frequency polarimetric study of the radio-quiet Seyfert galaxy NGC 4235 using the upgraded Giant Metrewave Radio Telescope (uGMRT), aimed at constraining the Far…
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…
A Kpc-scale Radio Polarization Study of PG BL Lacs with the uGMRT
Janhavi Baghel, P. Kharb, T. Hovatta +3
We present here uGMRT band 4 (~650MHz) polarization images of 8 BL~Lac objects belonging to the Palomar-Green (PG) `blazar' sample. A large fraction of the sources (~63%) reveal co…
PG1004+130: Hybrid Morphology Source or a Restarted FRII? A uGMRT Polarimetric Investigation
Salmoli Ghosh, P. Kharb, J. Baghel +1
We present here the polarization image of the hybrid morphology (HYMOR) and broad-absorption line (BAL) quasar PG1004+130 at 694~MHz obtained with the upgraded Giant Metrewave Radi…
uGMRT Band 4 Polarimetry
Preeti Kharb, Silpa Sasikumar, Janhavi Baghel +1
This is a technical report for band 4 (550-900 MHz) polarization data with the upgraded GMRT (uGMRT). The report describes the band 4 polarization data analysis procedure and inclu…
Radio Polarization: A Powerful Resource for Understanding the Blazar Divide
Janhavi Baghel, P. Kharb, Silpa S. +2
With high-sensitivity kiloparsec-scale radio polarimetry, we can examine the jet-medium interactions and get a better understanding of the blazar divide in radio-loud (RL) AGN. We…
AGN Feedback Through Multiple Jet Cycles in the Seyfert Galaxy NGC 2639
Vaishnav V. Rao, Preeti Kharb, Rubinur K. +7
The Seyfert galaxy NGC 2639 was known to exhibit three episodes of AGN jet/lobe activity. We present here the upgraded Giant Metrewave Radio Telescope (uGMRT) 735 MHz image of NGC…
A Polarimetric Study of 9 PG Quasars with the VLA
Janhavi Baghel, P. Kharb, Silpa S. +2
We present polarization images of 9 radio-loud (RL) quasars from the VLA B-array at 6 GHz. These quasars belong to the Palomar-Green (PG) "blazar" sample comprising 16 RL quasars a…
A Polarization Study of 3 Blazars using the uGMRT at ~600 MHz
Janhavi Baghel, Silpa S., P. Kharb +2
We present results from our radio polarimetric study with the upgraded Giant Metrewave Radio Telescope (uGMRT) at Band 4 (550-850 MHz) of 3 blazars: radio-loud quasars 3C390.3, 4C7…
