  • RAD@home citizen science discovery of an active galactic nucleus spewing a large unipolar radio bubble on to its merging companion galaxy 
    Hota, Ananda; Dabhade, Pratik; Vaddi, Sravani; Konar, Chiranjib; Pal, Sabyasachi; Gulati, Mamta; Stalin, C. S; Avinash, Ck; Kumar, Avinash; Rajoria, Megha; Purohit, Arundhati (Oxford University Press on behalf of Royal Astronomical Society, 2022-11)
    Active galactic nucleus (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 of the merging ...
  • Relativistic Jet Motion in the Radio-quiet LINER Galaxy KISSR 872 
    Kharb, Preeti; Blackman, Eric G; Clausen-Brown, Eric; Mousumi Das; Schwartz, Daniel A; Siemiginowska, Aneta; Subramanian, S; Vaddi, Sravani (American Astronomical Society, 2024-02-20)
    We report superluminal jet motion with an apparent speed of βapp = 1.65 ± 0.57 in the radio-quiet (RQ) lowionization nuclear emission-line region (LINER) galaxy KISSR 872. This result comes from two-epoch phasereferenced ...
  • The sharpest ultraviolet view of the star formation in an extreme environment of the nearest Jellyfish Galaxy IC 3418 
    Hota, Ananda; Devaraj, A; Pradhan, A. C; Stalin, C. S; George, Koshy; Mohapatra, Abhisek; Rey, Soo-Chang; Ohyama, Youichi; Vaddi, Sravani; Pechetti, Renuka; Ramya, S; Jose, Jessy; Roy, Jayashree; Konar, Chiranjib (Indian Academy of Sciences, 2021-10)
    We present the far ultraviolet (FUV) imaging of the nearest Jellyfish or Fireball galaxy IC3418/VCC 1217, in the Virgo cluster of galaxies, using Ultraviolet Imaging Telescope (UVIT) onboard the AstroSat satellite. The ...
  • Tracking galaxy evolution through low-frequency radio continuum observations using SKA and citizen-science research using multi-wavelength data 
    Hota, A; Konar, C; Stalin, C. S; Vaddi, Sravani; Mohanty, Pradeepta K; Dabhade, Pratik; Arun, Sai; Bhoga, Dharmik; Rajoria, Megha; Sethi, Sagar (Indian Academy of Sciences, 2016-12)
    We present a brief review of progress in the understanding of general spiral and elliptical galaxies, through merger, star formation and AGN activities. With reference to case studies performed with the GMRT, we highlight ...
  • A VLA–GMRT look at 11 powerful FR II quasars 
    Vaddi, Sravani; Kharb, P; Daly, R. A; O’Dea, C P; Baum, S. A; Deo, D.K; Barbusca, T.C; Murali, Chintak (Oxford University Press on behalf of the Royal Astronomical Society, 2019-03)
    We present results from 1.4 and 5 GHz observations at matched resolution with the Karl G. Jansky Very Large Array (VLA) of 11 powerful 3C FR II quasars. We examine the 11 quasars along with a sample of 13 narrow-line FR II ...
