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…
FRB 121102: No supernova-like ejecta or magnetar power, hinting at a binary WD merger
Eli Waxman, Eran O. Ofek, Doron Kushnir
We use measurements of the time-dependent dispersion measure of the repeating FRB 121102, together with earlier radio observations of its associated persistent radio source (PRS),…
A cosmic formation site of silicon and sulphur revealed by a new type of supernova explosion
Steve Schulze, Avishay Gal-Yam, Luc Dessart +47
The cores of stars are the cosmic furnaces where light elements are fused into heavier nuclei. The fusion of hydrogen to helium initially powers all stars. The ashes of the fusion…
Coma cluster -ray and radio emission is consistent with a secondary electron origin for the radio halo
Doron Kushnir, Uri Keshet, Eli Waxman
Observations of diffuse, non-thermal radio emission spanning several megaparsecs have been documented in over 100 galaxy clusters. This emission, classified as giant radio halos (G…
Photometric prioritization of neutron star merger candidates
E. O. Ofek, N L. Strotjohann, I. Arcavi +12
Rapid identification of the optical counterparts of Neutron Star (NS) merger events discovered by gravitational wave detectors may require observing a large error region and siftin…
The Early Ultraviolet Light-Curves of Type II Supernovae and the Radii of Their Progenitor Stars
Ido Irani, Jonathan Morag, Avishay Gal-Yam +18
We present a sample of 34 normal SNe II detected with the Zwicky Transient Facility, with multi-band UV light-curves starting at days after explosion, as well as X-ray d…
