  • A global look into the world of interacting supernovae 
    Gangopadhyay, Anjasha; Misra, Kuntal; Kawabata, Koji; Dastidar, Raya; Singh, Mridweeka (Indian Academy of Sciences, 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 ...

    Kumar, Harsh; Gupta, Rahul; Saraogi, Divita; Ahumada, Tomás; Andreoni, Igor; Anupama, G. C; Aryan, Amar; Barway, Sudhanshu; Bhalerao, Varun; Chandra, Poonam; Coughlin, Michael W; Dimple; Dutta, Anirban; Ghosh, Ankur; Ho, Anna Y. Q; Kool, E. C; Kumar, Amit; Medford, Michael S; Misra, Kuntal; Pandey, Shashi B; Perley, Daniel A; Riddle, Reed; Ror, Amit Kumar; Setiadi, Jason M; Yao, Yuhan (Oxford University Press on behalf of Royal Astronomical Society, 2022-06)
    We present results from extensive broadband follow-up of GRB 210204A over the period of 30 d. We detect optical flares in the afterglow at 7.6 × 105 s and 1.1 × 106 s after the burst: the most delayed flaring ever detected ...

Andrew; Jha, Saurabh W.; Im, Hyobin; Taggart, Kirsty; Andrews, Jennifer; Hiramatsu, Daichi; Teja, Rishabh Singh; Pellegrino, Craig; Foley, Ryan J.; Joshi, Arti; Anupama, G. C; Bostroem, K. Azalee; Burke, Jamison; Camacho-Neves, Yssavo; Dutta, Anirban; Kwok, Lindsey A.; McCully, Curtis; Pan, Yen-Chen; Siebert, Matt; Srivastav, Shubham; Szalai, Tamás; Swift, Jonathan J.; Yang, Grace; Zhou, Henry; DiLullo, Nico; Scheer, Jackson (American Astronomical Society, 2023-08-10)
    We present the optical photometric and spectroscopic analysis of two Type Iax supernovae (SNe), 2018cni and 2020kyg. SN 2018cni is a bright Type Iax SN (MV,peak = −17.81 ± 0.21 mag), whereas SN 2020kyg (MV,peak = −14.52 ± ...
  • Optical studies of a bright Type Iax supernova SN 2020rea 
    Singh, Mridweeka; Misra, Kuntal; Sahu, D. K; Ailawadhi, Bhavya; Dutta, Anirban; Howell, D. Andrew; Anupama, G. C; Bostroem, K.

    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) = ...
  • SN 2017gmr: An Energetic Type II-P Supernova with Asymmetries 
    Andrews, Jennifer E.; Sand, D. J.; Valenti, S.; Smith, Nathan; Dastidar, Raya; Sahu, D. K.; Misra, Kuntal; Singh, A; Hiramatsu, D; Brown, P. J.; Hosseinzadeh, G.; Wyatt, S.; Vinko, J.; Anupama, G. C; & 62 Co-authors (IOP Publishing, 2019-12)
    We present high-cadence UV, optical, and near-infrared data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the fi rst 180 days. SN 2017gmr does not show signs of narrow, ...

Andrew; Wang, Xiaofeng; Mo, Jun; Yan, Shengyu; Hiramatsu, Daichi; Pellegrino, Craig; Anupama, G. C; Joshi, Arti; Bostroem, K. Azalee; Burke, Jamison; McCully, Curtis; Rama Subramanian, V; Li, Gaici; Xi, Gaobo; Li, Xin; Li, Zhitong; Srivastav, Shubham; Im, Hyobin; Dutta, Anirban (American Astronomical Society, 2024-04-10)
    We present optical observations and analysis of the bright type Iax supernova SN 2020udy hosted by NGC 0812. The evolution of the light curve of SN 2020udy is similar to that of other bright type Iax SNe. Analytical modeling ...
  • Supernova 2012aw – a high-energy clone of archetypal Type IIP SN 1999em 
    Bose, Subhash; Kumar, Brijesh; Sutaria, F. K; Kumar, Brajesh; Roy, Rupak; Bhatt, V. K; Pandey, S. B; Chandola, H. C; Sagar, R; Misra, Kuntal; Chakraborti, Sayan (Oxford University Press, 2013-08-11)
    We present densely sampled UBVRI/griz photometric and low-resolution (6–10 Å) optical spectroscopic observations from 4 to 270 d after explosion of a newly discovered Type II SN 2012aw in a nearby (∼9.9 Mpc) galaxy M95. ...
