GRB 230204B: GIT Discovery of a Fast Fading Afterglow Associated with an Energetic GRB from a Massive-Star Progenitor
Vishwajeet Swain, Varun Bhalerao, Harsh Kumar +19
We present a comprehensive multi-wavelength study of a bright gamma-ray burst GRB 230204B, analyzing both prompt and afterglow emissions. This GRB is highly energetic, with an isot…
ZTF25abjmnps (AT2025ulz) and S250818k: A Candidate Superkilonova from a Sub-threshold Sub-Solar Gravitational Wave Trigger
Mansi M. Kasliwal, Tomas Ahumada, Robert Stein +61
On August 18, 2025, the LIGO-Virgo-KAGRA collaboration reported gravitational waves from a sub-threshold binary neutron star merger. If astrophysical, this event would have a surpr…
GRB 250704B: An Off-axis Short GRB with a Long-Lived Afterglow Plateau
Vishwajeet Swain, Tomás Ahumada, Sameer K. Patil +27
We present a detailed multi-wavelength afterglow study of the short GRB 250704B, extensively monitored in optical and near-infrared bands. Its afterglow displays an unusually long-…
Challenging Classical Paradigms: Recurrent Nova M31N 2017-01e, a BeWD system in M31?
Shatakshi Chamoli, Judhajeet Basu, Sudhanshu Barway +3
M31N 2017-01e is the second-fastest recurrent nova known, with a recurrence period of 2.5 years in the Andromeda Galaxy (M31). This system exhibits a unique combination of properti…
Efficacy of Galaxy Catalogues for following up gravitational wave events
Tamojeet Roychowdhury, Harsh Choudhary, Varun Bhalerao +6
The detection of gravitational waves (GW) by the LIGO-Virgo-KAGRA (LVK) network has opened up a new era in astrophysics. The identification of the electromagnetic counterparts of G…
LIGO/Virgo/KAGRA neutron star merger candidate S250206dm: Zwicky Transient Facility observations
Tomás Ahumada, Shreya Anand, Mattia Bulla +49
We present the searches conducted with the Zwicky Transient Facility (ZTF) in response to S250206dm, a bona fide event with a false alarm rate of one in 25 years, detected by the I…
The Jetted Tidal Disruption Event AT2022cmc: Investigating Connections to the Optical Tidal Disruption Event Population and Spectral Subclasses Through Late-Time Follow-up
Erica Hammerstein, S. Bradley Cenko, Igor Andreoni +14
AT2022cmc is the first on-axis jetted tidal disruption event (TDE) to be discovered at optical wavelengths. The optically bright nature of AT2022cmc presents an unprecedented oppor…
A White Paper on The Multi-Messenger Science Landscape in India
Samsuzzaman Afroz, Sanjib Kumar Agarwalla, Dipankar Bhattacharya +35
The multi-messenger science using different observational windows to the Universe such as Gravitational Waves (GWs), Electromagnetic Waves (EMs), Cosmic Rays (CRs), and Neutrinos o…
Discovery of a new phase-transient cyclotron line in A0535+26: Constraints on the accretion geometry
Ashwin Devaraj, Biswajit Paul, Varun Bhalerao +1
In November 2020, A0535+26 underwent one of its brightest outbursts, reaching nearly 12 Crab in X-ray flux. Observed by \textit{Insight-HXMT}, \textit{NuSTAR}, \textit{NICER}, and…
Multi-Wavelength Analysis of AT 2023sva: a Luminous Orphan Afterglow With Evidence for a Structured Jet
Gokul P. Srinivasaragavan, Daniel A. Perley, Anna Y. Q. Ho +50
We present multi-wavelength analysis of ZTF23abelseb (AT 2023sva), an optically discovered fast-fading ( mag in days), luminous ( mag) and…
