Citizen Science Research with the Square Kilometre Array Observatory (SKAO)
Ananda Hota, Pratik Dabhade, M. J. Hardcastle +8
Over the past two decades, internet-enabled citizen science research (CSR) has contributed to significant discoveries while involving millions of people in the research process. Ou…
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…
Spectral analysis of magnetized advective accretion flows around rotating black holes
Mayank Pathak, Shubhrangshu Ghosh, Banibrata Mukhopadhyay
The spectra of an accretion disk around black holes are the basic diagnostic tool to enlighten the underlying flows and then black holes. Accretion flows around black holes, howeve…
Spherical accretion in the Schwarzschild spacetime in the Newtonian analogous construct
Shubhrangshu Ghosh, Souvik Ghose, Kalyanbrata Pal +2
The velocity-dependent Newtonian analogous potentials (NAPs) corresponding to general relativistic (GR) spacetimes accurately capture most of the relativistic features, including a…
Test of conformal theory of gravity as an alternative paradigm to dark matter hypothesis from gravitational lensing studies
Shubhrangshu Ghosh, Mahasweta Bhattacharya, Yanzi Sherpa +1
Weyl's conformal gravity theory, which is considered as a compelling alternative to general relativity theory, has been claimed to describe the observed flat rotation curve feature…
Spherical accretion in giant elliptical galaxies: multi-transonicity, shocks, and implications on AGN feedback
Sananda Raychaudhuri, Shubhrangshu Ghosh, Partha S. Joarder
Isolated massive elliptical galaxies, or that are present at the center of cool-core clusters, are believed to be powered by hot gas accretion directly from their surrounding hot X…
