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…
Using Type-II Cepheids as Extragalactic Standard Candles: Distances to M31
V. D. Pipwala, H. N. Lala, B. Lemasle +3
Several standard candles have been tested and used to measure accurate extragalactic distances over the past decades. There have been discussions regarding the possibility of using…
RAD@home citizen science discovery of an AGN spewing a large unipolar radio bubble onto its merging companion galaxy
Ananda Hota, Pratik Dabhade, Sravani Vaddi +8
AGN feedback during galaxy merger has been the most favoured model to explain black hole-galaxy co-evolution. However, how the AGN-driven jet/wind/radiation is coupled with the gas…
The radio source in Abell 980: A Detached-Double-Double Radio Galaxy?
Gopal-Krishna, Surajit Paul, Sameer Salunkhe +1
It is argued that the new morphological and spectral information gleaned from the recently published LoFAR Two meter Sky Survey data release 2 (LoTSS-2 at 144 MHz) observations of…
Deciphering the ultra-steep spectrum diffuse radio sources discovered in the cool-core cluster Abell~980
Sameer Salunkhe, Surajit Paul, Gopal-Krishna +2
Clusters of galaxies are excellent laboratories for studying recurring nuclear activity in galactic nuclei since their hot gaseous medium can vastly prolong the detectability of th…
Fraction of broad absorption line quasars in different radio morphologies
Akhil Nair, M. Vivek
In this study, we investigated the orientation model of Broad Absorption Line (BAL) quasars using a sample of sources that are common in Sloan Digital Sky Survey (SDSS) Data Releas…
