  • A 1 bit Raw Voltage-recording System for Dedicated Observations of Transients at Low Radio Frequencies 
    Bane Kshitij, Suhas Trupti; Barve, Indrajit V; Gireesh, G. V. S; Kathiravan, C; Ramesh, R (American Astronomical Society, 2024-06)
    Recently we had reported commissioning of a prototype for pulsar observations at low radio frequencies (<100 MHz) using log-periodic dipole antennas in the Gauribidanur Radio Observatory (≈77°E, 14°N) near Bangalore in ...
  • Additional calibration of the ultraviolet imaging telescope on board AstroSat 
    Tandon, S. N; Postma, J; Joseph, P; Devaraj, A; Subramaniam, A; Subramaniam, I. V; George, K; Ghosh, S. K; Girish, V; Hutchings, J. B; Kamath, P. U; Kathiravan, S; Kumar, A; Lancelo, J. P; Leahy, D; Mahesh, P. K; Mohan, R; Nagabhushana, S; Pati, A. K; Kameswara Rao, N; Sankarasubramanian, K; Sriram, S; Stalin, C. S (IOP Publishing, 2020-04)
    Results of the initial calibration of the Ultra-Violet Imaging Telescope (UVIT) were reported earlier by Tandon et al. The results reported earlier were based on the ground calibration as well as the first observations in ...

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 ...
  • The Stability of Fiber Spectrographs in the Faint-source Regime 
    Bundy, Kevin; Law, David; MacDonald, Nick; Westfall, Kyle B.; Sivarani, T; Divakar, Devika; Bershady, Matthew; Gu, Meng; Yan, Renbin; Roy, Namrata; Poppett, Claire; Drory, Niv (American Astronomical Society, 2022-09-01)
    The use of optical fibers in astronomical instrumentation offers high-multiplex and light-gathering flexibility. However, with most previous fiber spectrographs optimized for large fields of view on modest-aperture telescopes, ...
  • Variable stars in M37 
    Dar, A. A; Parihar, P. S; Saleh, P; Malik, M. A (IOP Publishing, 2018-12)
    The CCD photometric observations of open star cluster M37 (NGC 2099) were carried out up to a limiting magnitude of V ~ 20 in both B and V filters to search for variable stars using a 2k × 4k CCD and the 1.3 m telescope ...
