Galactic-scale evolution of classical and complex radio galaxies. Impact of ambient morphology and jet geometry
Gourab Giri, Prajnadipt Ghosh, Ravi Joshi +9
Extragalactic jets exhibit a wide range of propagation orientations relative to the host galaxy's principal axis. This study investigate the spatiotemporal evolution of jets as a f…
Probing the formation of megaparsec-scale giant radio galaxies II. Continuum & polarization behavior from MHD simulations
Gourab Giri, Christian Fendt, Joydeep Bagchi +4
The persistence of radiative signatures in giant radio galaxies remains a frontier topic of research, with contemporary telescopes revealing intricate features that require investi…
Discovery of a Ultra Steep Spectrum Radio Halo in the MeerKAT-South Pole Telescope Survey
Isaac S. Magolego, Roger P. Deane, Kshitij Thorat +15
Radio halos are diffuse synchrotron sources that trace the turbulent intracluster medium (ICM) of galaxy clusters. However, their origin remains unknown. Two main formation models…
HI gas in the rejuvenated radio galaxy PKS 2014-55
Leon Mtshweni, Kshitij Thorat, Roger P. Deane +17
We present new high-spectral-resolution MeerKAT observations of absorption against the central region of the restarted, giant, X-shaped radio galaxy PKS2014-55, which…
MeerKAT 1.3 GHz Observations of the Wide Angle Tail Radio Galaxy J17122435
William Cotton, Gourab Giri, P. J. Agnihotri +3
We present full polarization MeerKAT images of the wide-angle tail, giant radio galaxy J17122435 at 1.3 GHz with 7.\asec5 resolution and an RMS sensitivity of 8 Jy beam$^{-1…
Probing the Formation of Megaparsec-scale Giant Radio Galaxies (I): Dynamical Insights from MHD Simulations
Gourab Giri, Joydeep Bagchi, Kshitij Thorat +3
Giant radio galaxies (GRGs), a minority among the extended-jetted population, form in a wide range of jet and environmental configurations, complicating the identification of the g…
