Multi-scale variability in the optical afterglow of GRB 251013C from high-cadence LAST observations

R. Konno, E. O. Ofek, S. Garrappa +8

Context. Optical afterglows of gamma-ray bursts (GRBs) are often described by smooth power-law decays, but deviations such as flares and rebrightenings provide important constraint…

Lepto-hadronic modeling of blazars associated with well-reconstructed high-energy neutrino events

Leonard Pfeiffer, Margot Boughelilba, Simone Garrappa +3

The association of active galactic nuclei (AGN) with high-energy neutrinos has been studied through population and individual source analyzes, but whether these associations reflec…

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 u…

The Type IIn SN 2025cbj coincidence with the high-energy neutrino IceCube-250421A

S. Garrappa, E. A. Zimmerman, T. Wasserman +14

Context. The origin of the astrophysical high-energy neutrino flux remains uncertain. Core-collapse supernovae with strong CSM interaction (Type IIn) are compelling candidates for…

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…

Very-high-energy gamma-ray detection and long-term multi-wavelength view of the flaring blazar B2 1811+31

K. Abe, S. Abe, J. Abhir +231

Among the blazars whose emission has been detected up to very-high-energy (VHE; 100 GeV < E < 100 TeV) gamma rays, intermediate synchrotron-peaked BL Lacs (IBLs) are quite rare. Th…
