  • Black hole demographics from TDE modeling 
    Mageshwaran, T; Mangalam, A (Cambridge University Press, 2018-05)
    The occurence rate of tidal disruption events (TDEs) by survey missions depend on the black hole mass function of the galaxies, properties of the stellar cusp and mass of the central black hole. Using a power law density ...
  • A multifrequency study of the large radio galaxies 3C46 and 3C452 
    Nandi, S; Pirya, A; Pal, S; Konar, C; Saikia, D. J; Singh, M (Wiley-Blackwell, 2010-05)
    We present low-frequency observations starting from ∼150 MHz with the Giant Metrewave Radio Telescope, and high-frequency observations with the Very Large Array of two large radio galaxies 3C46 and 3C452. These observations ...
  • A multiwavelength study of the dual nuclei in Mrk 212 
    Rubinur, K; Kharb, P; Das, M; Rahna, P. T; Honey, M; Paswan, A; Vaddi, S; Murthy, J (Oxford University Press on behalf of the Royal Astronomical Society, 2021-01)
    We present radio observations of the galaxy merger remnant Mrk 212 with the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT). Mrk 212 has two previously known radio sources associated ...
  • The search for binary black holes in Seyferts with double peaked emission lines 
    Kharb, P; Mousumi Das; Subramanian, S; Paragi, Z (Astronomical Society of India, 2015-04)
    We discuss results from very long baseline interferometry (VLBI) observations of two Seyfert galaxies with double peaked emission lines in their SDSS optical spectra. Such AGN are potential candidates for the presence ...
  • Young Stars and Nonstellar Emission in the Aligned Radio Galaxy 3C 256 
    Simpson, C; Eisenhardt, P; Armus, L; Chokshi, A; Dickinson, M; Djorgovski, S. G; Elston, R; Jannuzi, B. T; McCarthy, P. J; Pahre, M. A; Soifer, B. T (The American Astronomical Society, 1999-11)
    We present ground-based images of the z=1.824 radio galaxy 3C 256 in the standard BVRIJHK filters and an interference filter centered at 8800 Å, a Hubble Space Telescope image in a filter dominated by Lyα emission (F336W), ...
