  • A global look into the world of interacting supernovae 
    Gangopadhyay, Anjasha; Misra, Kuntal, et.al.; Kawabata, Koji S; Dastidar, Raya; Singh, Mridweeka (Journal Astrophysical Astronomy, 2022-12)
    Interacting supernovae (SNe) IIn and Ibn show narrow emission lines and have always been a mysterious and unsolved genre in SNe physics. We present a comprehensive analysis of the temporal and spectroscopic behavior of ...
  • Optical characterization and radial velocity monitoring with Belgian and Indian telescopes (ORBIT): the eclipsing binaries EPIC 211982753 and EPIC 211915147 
    Panchal, Alaxender; Joshi, Y. C.; Cat, Peter De; Lampens, Patricia ,et.al. (Monthly Notices of the Royal Astronomical Society, 2023-05)
    The K2 eclipsing binary (EB) candidates EPIC 211982753 (hereinafter called EPIC2753) and EPIC 211915147 (hereinafter called EPIC5147) are characterized with the help of photometric and high-resolution spectroscopic data. ...
  • Optical studies of a bright Type Iax supernova SN 2020rea 
    Singh, Mridweeka et.al.; Misra, Kuntal; Ailawadhi, Bhavya (Monthly Notices of the Royal Astronomical Society, 2022-12)
    We present optical photometric and spectroscopic analysis of a Type Iax supernova (SN) 2020rea situated at the brighter luminosity end of Type Iax supernovae (SNe). The light curve decline rate of SN 2020rea is m15(g) = ...
  • Photometric and spectroscopic analysis of the Type II SN 2020jfo with a short plateau 
    Ailawadhi, B. ,et.al.; Misra, K.; Ghosh, A.; Dimple; Jha, V. K.; Kumar, A.; Pandey, S. B. (Monthly Notices of the Royal Astronomical Society, 2023-02)
    We present high-cadence photometric and spectroscopic observations of SN 2020jfo in ultraviolet and optical/near-infrared bands starting from ∼3 to ∼434 d after the explosion, including the earliest data with the 10.4-m ...
  • SN 2016iyc: a Type IIb supernova arising from a low-mass progenitor 
    Aryan, Amar; Pandey, S. B. ,et.al.; Kumar, Amit; Gupta, Rahul; Ror, Amit Kumar (Monthly Notices of the Royal Astronomical Society, 2022-12)
    In this work, photometric and spectroscopic analyses of a very low-luminosity Type IIb supernova (SN) 2016iyc have been performed. SN 2016iyc lies near the faint end among the distribution of similar supernovae (SNe). ...
  • Spectroscopic reverberation mapping of Quasar PKS 0736 + 017: broad-line region and black-hole mass 
    Pandey, Shivangi; Rakshit, Suvendu; Woo, Jong-Hak; Stalin, C. S. (Monthly Notices of the Royal Astronomical Society, 2022-10)
    To understand the mass distribution and co-evolution of supermassive black holes with their host galaxy, it is crucial to measure the black hole mass of AGN. Reverberation mapping is a unique tool to estimate the black ...
  • Type Ia supernovae SN 2013bz, PSN J0910 + 5003, and ASASSN-16ex: similar to 09dc-like? 
    Tiwari, S.; Chakradhari, N. K.; Sahu, D. K.; Anupama, G. C.; Kumar, B.; Sahu, K. R. (Monthly Notices of the Royal Astronomical Society, 2023-06)
    We present optical photometric and spectroscopic studies of three supernovae (SNe): SN 2013bz, PSN J0910 + 5003, and ASASSN-16ex (SN 2016ccj). UV–optical photometric data of ASASSN-16ex obtained with the Swift ...
