Multiwavelength View of Black Hole X-ray Binary Swift J151857.0-572147
Manoj Mandal, Sachindra Naik, Souvik Manik +1
We investigate multiwavelength timing and spectral properties of the newly discovered black hole X-ray binary Swift J151857.0-572147 during its 2024 outburst using observations fro…
Source Finding and Characterisation for SKAO Science
Sabyasachi Pal, Souvik Manik, M Carmen Toribio +8
The advancements in highly sensitive and powerful radio telescopes, including the Square Kilometre Array Observatory (SKAO) and its precursors, MeerKAT, ASKAP, MWA, and HERA, will…
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…
RAD@home discovery of a bow-and-arrow radio galaxy tracing a ~560 kpc bow-shock structure in a multi-halo environment
Ananda Hota, Pratik Dabhade, Shubhrangshu Ghosh +9
We report the RAD@home citizen science discovery of a unique bow-and-arrow-shaped radio galaxy (BAARG; RAD J104501.6+352852, z = 0.159) identified in LoTSS DR2. The source exhibits…
