Tracing the Origin of Circular-Symmetry Diffuse Radio Sources in the Next-Generation SKAO Era
Sabyasachi Pal, Shobha Kumari, Souvik Manik +2
Circularly symmetric diffuse radio sources represent a recently recognized and rare class of extragalactic synchrotron-emitting structures whose physical origin remains uncertain.…
Exploring the Influence of the Jet-environment Interactions on the Observed Asymmetry of Extragalactic Radio Sources with SKAO
Sabyasachi Pal, Souvik Manik, Shobha Kumari +1
Several observational and theoretical studies have suggested that the observed arm-length asymmetries in extragalactic radio sources are primarily driven by interactions between ra…
Probing AGN duty cycle and cluster-driven morphology in a giant episodic radio galaxy
Shobha Kumari, Sabyasachi Pal, Surajit Paul +1
The evolution of radio jet morphology and its energetics is significantly influenced by the environment in which the host galaxy resides. As giant radio galaxies (GRGs) often exten…
Circular Mystery: Exploring Diffuse Emission Surrounding a Radio Galaxy with uGMRT and VLA Multiwavelength Observations
Shobha Kumari, Sabyasachi Pal, Souvik Manik
We report the discovery of J1218+1813, a circular diffuse radio source detected in the Very Large Array (VLA) FIRST survey at 1400 MHz. The source has an angular diameter of approx…
Hybrid Morphology Radio Sources from the MeerKAT Absorption Line Survey (MALS): Radio, Mid-infrared and Environmental Characteristics
Souvik Manik, Shobha Kumari, Netai Bhukta +2
Hybrid morphology radio sources (HyMoRSs) are a rare subclass of radio galaxies that display a Fanaroff-Riley type I (FR I) morphology on one side of the central supermassive black…
J0011+3217: A peculiar radio galaxy with a one-sided secondary lobe and misaligned giant primary lobes
Shobha Kumari, Sabyasachi Pal, Martin J. Hardcastle +1
From the LOFAR Two-metre Sky Survey second data release (LoTSS DR2) at 144 MHz, we identified a peculiar radio galaxy, J0011+3217. It has a large, one-sided diffuse secondary wing…
