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),…

Composite sub-micron solid particles engineered to enable safe, controllable, efficient, and practical SAI

A. Spector, T. Kislev, Y. Segev +2

The properties of candidate particles for solar radiation management (SRM) through stratospheric aerosol injection (SAI) should comply with safety, controllability, and functionali…

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…

Preliminary results of the Single Event Effect testing for the ULTRASAT sensors

Vlad Dumitru Berlea, Arooj Asif, Merlin F. Barschke +18

ULTRASAT (ULtra-violet TRansient Astronomy SATellite) is a wide-angle space telescope that will perform a deep time-resolved all-sky survey in the near-ultraviolet (NUV) spectrum.…

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…

UV to near-IR observations of the DART-Dimorphos collision

E. O. Ofek, D. Kushnir, D. Polishook +15

The impact of the Double Asteroid Redirection Test (DART) spacecraft with Dimorphos allows us to study asteroid collision physics, including momentum transfer, the ejecta propertie…

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…
