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…
Serendipitous discovery of a spiral host in a 2 Mpc double-double lobed radio galaxy
Sagar Sethi, Agnieszka Kuźmicz, Dominika Hunik +1
We present the serendipitous discovery of a double-double radio galaxy (DDRG) with a projected linear size exceeding 2 Mpc, hosted by a spiral galaxy. This unique combination of a…
Study of giant radio galaxies using spectroscopic observations from the Himalayan Chandra Telescope
Sagar Sethi, Pratik Dabhade, K. G. Biju +2
We present the results of spectroscopic observations of host galaxies of eleven candidate giant radio galaxies (GRGs), powered by active galactic nuclei (AGNs), conducted with the…
Discovery of 100 kpc narrow curved twin jet in S-shaped giant radio galaxy: J0644+1043
Sagar Sethi, Agnieszka Kuźmicz, Marek Jamrozy +1
We report the discovery of an S-shaped morphology of the radio galaxy J06441043 imaged with a 30 Jy sensitive 525 MHz broadband (band 3 4) uGMRT map. Dedicated spectrosc…
