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^{…
Binary neutron stars in the next-generation era: Multi-messenger detection prospects and constraints on the equation of state, mass distribution, and cosmology
Hauke Koehn, Thibeau Wouters, Gilad Sadeh +5
Next-generation gravitational-wave (GW) observatories will provide crucial insights into the nature of neutron star (NS) matter and the cosmological expansion history. We estimate…
The hydrodynamics of stratified ultra-relativistic outflows and the origin of GRB X-ray plateaus
Gilad Sadeh, Kenta Hotokezaka, Masaru Shibata
The origin of the X-ray plateau phase observed in a large fraction of gamma-ray burst afterglows remains debated. We present a novel analytic framework for the hydrodynamics of ult…
Inferring kilonova ejecta photospheric properties from early blackbody spectra
Gilad Sadeh
We present simple analytic corrections to the standard blackbody fitting used for early kilonova emission. We consider a spherical, relativistically expanding shell that radiates t…
Synchrotron break frequencies of mildly-to-highly relativistic outflows observed off-axis
Gilad Sadeh
We consider the synchrotron spectrum produced by mildly-to-highly relativistic collisionless shocks. Simple analytic formulae are derived for the break frequencies (peak frequency,…
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…
Late-time non-thermal emission from mildly relativistic tidal ejecta of compact objects merger
Gilad Sadeh
Mergers of compact objects (binary neutron stars, BNS, or neutron star-black hole, NSBH) with a substantial mass ratio () are expected to produce a mildly relativistic eject…
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…
Non-thermal emission from mildly relativistic dynamical ejecta of neutron star mergers
Gilad Sadeh, Or Guttman, Eli Waxman
Binary neutron star mergers are expected to produce fast dynamical ejecta, with mildly relativistic velocities extending to . We consider the radio to X-ray synchrotron…
