  • Astreaks: astrometry of NEOs with trailed background stars 
    Sharma, Kritti; Kumar, Harsh; Choudhary, Harsh; Bhalerao, Varun; Swain, Vishwajeet; Bolin, Bryce; Anupama, G. C; Barway, Sudhanshu; Joharle, Simran; Shenoy, Vedant (Oxford University Press on behalf of Royal Astronomical Society, 2023-09)
    The detection and accurate astrometry of fast-moving near-Earth objects (NEOs) has been a challenge for the follow-up community. Their fast apparent motion results in streaks in sidereal images, thus affecting the telescope’s ...
  • GROWTH on S190426c II: GROWTH-India Telescope search for an optical counterpart with a custom image reduction and candidate vetting pipeline 
    Kumar, Harsh; Bhalerao, Varun; Anupama, G. C; Barway, Sudhanshu; Coughlin, Michael W; De, Kishalay; Deshmukh, Kunal; Dutta, Anirban; Goldstein, Daniel A; Jassani, Adeem; Joharle, Simran; Karambelker, Viraj; Khandagale, Maitreya; Kumar, B; Saraogi, Divita; Sharma, Yashvi; Shenoy, Vedant; Singer, Leo; Singh, A; Waratkar, Gaurav (Oxford University Press on behalf of Royal Astronomical Society, 2022-11)
    S190426c/GW190426 152155 was the first probable neutron star–black hole merger candidate detected by the LIGO-Virgo Collaboration. We undertook a tiled search for optical counterparts of this event using the 0.7-m ...

T; Norbu, Rigzin; Sharma, Tarun Kumar; Stanzin, Jigmet; Stanzin, Tsewang; Stanzin, Urgain (American Astronomical Society, 2022-09-01)
    We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illuminated camera that gives a 0fdg82 field of ...
  • Outbursts of Comet 67P/Churyumov-Gerasimenko 
    Sharma, Kritti; Kelley, Michael S. P; Joharle, Simran; Kumar, Harsh; Swain, Vishwajeet; Bhalerao, Varun; Anupama, G. C; Barway, Sudhanshu (IOP Publishing, 2021-12)
    We monitored the comet 67P/Churyumov-Gerasimenko close to its perihelion in November 2021 with the GROWTH-India Telescope. We observed two outbursts of this comet on 2021 October 29.940 and November 17.864 UTC, -3.12 days ...
  • SN 2020sck: Deflagration in a Carbon-Oxygen White Dwarf 
    Dutta, Anirban; Sahu, D. K; Anupama, G. C; Joharle, Simran; Kumar, Brajesh; Nayana, A. J; Singh, Avinash; Kumar, Harsh; Bhalerao, Varun; Barway, Sudhanshu (American Astronomical Society, 2022-02-01)
    We present optical UBVRI photometry and low-to-medium resolution spectroscopic observations of type Iax supernova SN 2020sck spanning −5.5 days to +67 days from maximum light in the B-band. From the photometric analysis ...
