  • 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 ...
  • A Radio and ultraviolet study of dual nuclei in galaxies 
    Rubinur, K (Indian Institute of Astrophysics, 2019-04)
    This thesis is aimed at studying dual nuclei in galaxies using radio and UV observations. Dual nuclei are formed during galaxy mergers in our Universe. Since we know that almost all nearby galaxies host a super-massive ...
  • Searching for dual active galactic nuclei 
    Rubinur, K; Das, Mousumi; Kharb, P (Indian Academy of Sciences, 2018-02)
    Binary or dual active galactic nuclei (DAGN) are expected from galaxy formation theories. However, confirmed DAGN are rare and finding these systems has proved to be challenging. Recent systematic searches for DAGN using ...
  • Searching for dual AGN in galaxies with double-peaked emission line spectra using radio observations 
    Rubinur, K; Mousumi Das; Kharb, P (Oxford University Press on behalf of the Royal Astronomical Society, 2019-04)
    Supermassive black hole (SMBH) binaries form due to galaxy mergers and minor accretion events. When the SMBHs are accreting, they form dual or binary AGN and can give rise to double-peaked emission lines in the optical ...
  • Study of star formation in dual nuclei galaxies using UVIT observations 
    Rubinur, K; Das, M; Kharb, P; Yadav, J; Mondal, C; Rahna, P. T (Oxford University Press on behalf of Royal Astronomical Society., 2024-03)
    We have used the Ultraviolet Imaging Telescope (UVIT) aboard AstroSat to study star formation in a sample of nine dual nuclei galaxies with separations <≈ 11 kpc, which is an expected outcome of galaxy mergers. To minimize ...
  • Understanding galaxy mergers and AGN feedback with UVIT 
    Rubinur, K; Mousumi Das; Kharb, Preeti; Rahne, P. T (Cambridge University Press, 2021-01)
    Simulations expect an enhanced star-formation and active galactic nuclei (AGN) activity during galaxy mergers, which can lead to formation of binary/dual AGN. AGN feedback can enhance or suppress star-formation. We have ...
