Causal self-consistency of the Blandford--McKee self-similar solution

Gilad Sadeh, Tamar Faran, Doron Kushnir +1

The Blandford--McKee (BM) solution describes the ultra-relativistic self-similar flow behind a strong spherical blast wave propagating into an external density profile $\propto r^{…

The high entropy of the UHECR arrival direction distribution favors a light composition

Nimrod Strasman, Eli Waxman

We analyze the constraints on the composition of ultra-high-energy cosmic rays (UHECRs), and on the density and distribution of their sources, that may be inferred from their arriv…

High-Energy Neutrinos from Supernova Shock Breakouts in Circumstellar Media: Light Curves, Spectra, and Contribution to the Extragalactic Neutrino Background

Tal Wasserman, Eli Waxman, Kohta Murase

Enhanced mass loss from core-collapse supernova (SN) progenitors shortly before explosion appears to be common, creating a compact, optically thick circumstellar medium (CSM) at $\…

Supernovae Exploding within Dense Extended Material: Early Emission Regimes and Degeneracies in Parameter Inference from Observations

Tal Wasserman, Eli Waxman

Early light curves of many core-collapse supernovae (SNe) are thought to be powered by the interaction of the shock wave with optically thick extended material, either a bound enve…

The Optical to X-ray Luminosity and Spectrum of Supernova Wind Breakouts

Tal Wasserman, Nir Sapir, Peter Szabo +1

Observations indicate that optically thick circum-stellar medium (CSM) at radii of cm around Type II core-collapse supernovae (SN) progenitors is common (and may…

The non-thermal emission following GW170817 is consistent with a conical radially-stratified outflow with initial Lorentz factor

Gilad Sadeh, Eli Waxman

We show that the non-thermal radio to X-ray emission following the neutron star merger GW170817 is consistent with synchrotron emission from a collisionless shock driven into the i…

Shock cooling emission from explosions of massive stars: III. Blue Super Giants

J. Morag, N. Sapir, E. Waxman

Light emission in the first hours and days following core-collapse supernovae is dominated by the escape of photons from the expanding shock-heated envelope. In preceding papers, w…

The thermalization of -rays in radioactive expanding ejecta: A simple model and its application for Kilonovae and Ia SNe

Or Guttman, Ben Shenhar, Arnab Sarkar +1

A semi-analytic approximation is derived for the time-dependent fraction of the energy deposited by radioactive decay -rays in a homologously expanding plasma of genera…

An Analytic Description of Electron Thermalization in Kilonovae Ejecta

Ben Shenhar, Or Guttman, Eli Waxman

A simple analytic description is provided of the rate of energy deposition by -decay electrons in the homologously expanding radioactive plasma ejected in neutron star mergers,…

Non-thermal emission from mildly relativistic dynamical ejecta of neutron star mergers: spectrum and sky image

Gilad Sadeh, Noya Linder, Eli Waxman

Binary neutron star mergers are expected to produce fast dynamical ejecta, with mildly relativistic velocities extending to . In a preceding paper, we derived an analyti…
