Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

T. Komesh, A. Pozanenko, N. Pankov +37

We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt gamma-ray observations with exceptionally early simultaneous optical photometr…

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…

Characterising EP241107a: Multiwavelength Observations of an Einstein Probe-detected Fast X-ray Transient

D. Eappachen, A. Balasubramanian, Vishwajeet Swain +12

Fast X-ray Transients (FXTs) represent a new class of highly luminous transients in soft X-rays (0.3-10 keV) associated with violent astrophysical processes. They manifest as…

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…
