  • First Light Preparations of the 4 m ILMT 
    Kumar, Brajesh; Kumar, Hitesh; Dangwal, Khushal Singh; Rawat, Himanshu; Misra, Kuntal; Negi, Vibhore; Jaiswar, Mukesh Kumar; Dukiya, Naveen; Ailawadhi, Bhavya (Journal of Astronomical Instrumentation, 2022-12)
    The 4 m International Liquid Mirror Telescope (ILMT) is a zenith-pointing optical observing facility at ARIES Devasthal observatory (Uttarakhand, India). The ¯rst light preparatory activities of the ILMT were accomplished ...
  • Intranight optical variability of blazars and radio-quiet quasars using the ZTF survey 
    Negi, Vibhore; Krishna, Gopal; Joshi, Ravi; Chand, Hum; Wiita, Paul J.; Navaneeth, P. K.; Singh, Ravi S. (Monthly Notices of the Royal Astronomical Society, 2023-07)
    We explore the potential of the ongoing Zwicky Transient Facility (ZTF) survey for studying intranight optical variability (INOV) of active galactic nuclei (AGNs), in particular for picking rare events of large INOV ...
  • Intranight optical variability of TeV blazars with parsec-scale jets dominated by slow-moving radio knots 
    Negi, Vibhore; Krishna, Gopal; Chand, Hum; Britzen, Silke (Monthly Notices of the Royal Astronomical Society, 2023-09)
    BL Lac objects detected at TeV energies preferentially belong to the subclass called ‘high-frequency-peaked’ BL Lacs (HBLs). Parsec-scale radio jetsin these TeV-HBLs often show dominant,slow-moving radio knotsthat are at ...
  • Probable low-frequency quasi-periodic oscillations in blazars from the ZTF survey 
    Banerjee, Anuvab; Negi, Vibhore; Joshi, Ravi; Kumar, Nagendra; Wiita, Paul J.; Chand, Hum; Rawat, Nikita; Wu, Xue-Bing; Ho, Luis C. (Monthly Notices of the Royal Astronomical Society, 2023-12)
    We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-frequency QPO signal in five blazars observed ...
