Particle Acceleration and Depolarization in the Protostellar jet knots HH 80 and HH 81
A. G. Cheriyan, S. Vig, Nirupam Roy +4
Linearly polarized emission is a powerful tracer of magnetic field geometry and particle acceleration in protostellar jets. We present a polarimetric study of the HH objects HH 80…
Crossing the veil of the brightest radio relic in the sky MACS J0717.6+3745
A. Pasetto, O. Vilchis, A. Bonafede +3
We present high-frequency, full-polarisation Jansky Very Large Array (VLA) radio data at X-band of the radio relic: MACS J0717.5+3745. Radio relics trace shock waves in the intracl…
What drives kpc-scale outflows in Radio-Quiet AGN? Insights from a Polarimetric Study
Salmoli Ghosh, Preeti Kharb, Biny Sebastian +5
We present a review of our findings on the origin, drivers, nature, and impact of kiloparsec-scale radio emission in radio-quiet (RQ) AGN. Using radio polarimetric techniques, we p…
First detection of Circular Polarization in radio continuum towards a Massive Protostar
A. G. Cheriyan, S. Vig, Nirupam Roy +4
Polarization measurements provide strong constraints on magnetic fields in star-forming systems. While magnetic field estimates of a few kiloGauss (kG) have been obtained near the…
Magnetic field in the Lobes of the Seyfert Galaxy NGC3516: Suggestions of a Helical field
Salmoli Ghosh, P. Kharb, E. Sajjanhar +2
We present polarization images from the Karl G. Jansky Very Large Array (VLA) and the Giant {Metrewave} Radio Telescope (GMRT) at 5.5, 10 GHz and 663 MHz of the changing-look (CL)…
ngVLA Synthetic Observations of Ionized Gas in Massive Protostars
Jesús M. Jáquez-DomÃnguez, Roberto Galván-Madrid, Alfonso Trejo-Cruz +11
Massive star formation involves significant ionization in the innermost regions near the central object, such as gravitationally trapped H II regions, jets, ionized disks, or winds…
