  • GMRT H I study of giant low surface brightness galaxies 
    Mishra, A; Kantharia, N. G; Das, Mousumi; Omar, A; Srivastava, D. C (Oxford University Press on behalf of the Royal Astronomical Society, 2017-01)
    We present H I observations of four giant low surface brightness (GLSB) galaxies UGC 1378, UGC 1922, UGC 4422 and UM 163 using the Giant Meterwave Radio Telescope. We include H I results on UGC 2936, UGC 6614 and Malin 2 ...
  • Molecular gas and star formation in void galaxies 
    Das, Mousumi; Saito, T; Iono, D; Honey, M; Ramya, S (International Astronomical Union, 2016-10)
    We present the detection of molecular gas using CO(1–0) line emission and followup Hα imaging observations of galaxies located in nearby voids. The CO(1–0) observations were done using the 45m telescope of the Nobeyama ...
  • 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 ...
  • Testing a theoretical prediction for bar formation in galaxies with bulges 
    Kataria, Sandeep Kumar; Das, Mousumi; Barway, Sudhanshu (EDP Sciences, 2020-08)
    Earlier studies have shown that massive bulges impede bar formation in disk galaxies. Recent N-body simulations have derived a bar formation criterion that depends on the radial bulge force in a galaxy disk. We use those ...
