  • Low-frequency View of GW170817/GRB 170817A with the Giant Metrewave Radio Telescope. 
    Resmi, L. et al.; Misra, K. (Astrophysical journal, 2018-11)
    The short gamma-ray burst (GRB) 170817A was the first GRB associated with a gravitational-wave event. Due to the exceptionally low luminosity of the prompt γ-ray and the afterglow emission, the origin of both radiation ...
  • Refining the OJ 287 2022 impact flare arrival epoch 
    Valtonen, Mauri J. , et.al.; Gupta, Alok C. (Monthly Notices of the Royal Astronomical Society, 2023-06)
    The bright blazar OJ 287 routinely parades high brightness bremsstrahlung flares, which are explained as being a result of a secondary supermassive black hole (SMBH) impacting the accretion disc of a more massive primary ...
  • Search for merger ejecta emission from late-time radio observations of short GRBs using GMRT 
    Ghosh, Ankur; Vaishnava, C. S.; Resmi, L.; Misra, Kuntal; Arun, K. G.; Omar, Amitesh; Chakradhari, N. K. (Monthly Notices of the Royal Astronomical Society, 2024-01)
    In some cases, the merger of two neutron stars can produce a rapidly rotating and highly magnetized millisecond magnetar. A significant proportion of the rotational energy deposited to the emerging ejecta can produce a ...
