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…
