Early Multiwavelength Observations of AT 2026fgk: The Luminous Afterglow to Sub-luminous GRB 260310A, Identified Independently of a Gamma-ray Trigger
K. -R. Hinds, A. Y. Q. Ho, Y. Wagh +103
The origins of sub-luminous (\,erg\,s) gamma-ray bursts (GRBs) associated with broad-lined Type~Ic supernovae (Ic-BL SNe) are poorly…

A search for minute-time-scale flares from the transient AT\,2024wpp
Eran O. Ofek, Lior Ozer, Ruslan Konno +21
The AT 2018cow-like fast blue optical transient AT2022tsd showed a large number of few-minute-duration, high-luminosity (~10^43 erg/s) flares. We present an intensive search for su…

Accurate photometric calibration by fitting the system transmission
S. Garrappa, E. O. Ofek, S. Ben-Ami +10
Transforming the instrumental photometry of ground-based telescopes into a calibrated physical flux in a well-defined passband is a major challenge in astronomy. Along with the int…
