Observability of flashes from ejecta crashes in aspherical supernovae, with application to SN 2008D
Benjamin Scully, Christopher D. Matzner, Almog Yalinewich
A new class of transient, which has been hypothesized to accompany the explosion of an aspherical compact supernova, would arise when streams of ejecta collide outside the star. Ho…
The Moving Mirror model for Fast Radio Bursts
Almog Yalinewich, Ue-Li Pen
Recent observations of coherent radiation from the Crab pulsar (Bij et al 2021) suggest the emission is driven by an ultra - relativistic (), cold plasma flow. A relati…
Plug Disintegration in GRB Jet Eruption
Almog Yalinewich, Paz Beniamini
In this work we consider the eruption of a tenuous relativistic hydrodynamic jet from a dense baryonic envelope. As the jet moves out and away, it carries along and continues to ac…
The Propagation of Strong Shocks into Planetary and Stellar Atmospheres
Almog Yalinewich, Andrey Remorov
In this work we present a mathematical model for the propagation of the shock waves that occur in graded density profiles. These waves can occur in a wide range of astrophysical ev…
Crater Morphology of Primordial Black Hole Impacts
Almog Yalinewich, Matthew E. Caplan
In this work we propose a novel campaign for constraining relativistically compact MACHO dark matter, such as primordial black holes (PBHs), using the moon as a detector. PBHs of a…
Self Similar Adiabatic Strong Explosion in a Medium Gravitationally Free Falling to a Point Mass
Almog Yalinewich
We develop a generalisation to the classical Sedov Taylor explosion where the medium free falls to a point mass at the centre of the explosion. To verify our analytic results, we c…
Self similar Shocks in Atmospheric Mass Loss due to Planetary Collisions
Almog Yalinewich, Andrey Remorov
We present a mathematical model for the propagation of the shock waves that occur during planetary collisions. Such collisions are thought to occur during the formation of terrestr…
Optical Transient from an Explosion Close to the Stellar Surface
Almog Yalinewich, Christopher D. Matzner
We study the hydrodynamic evolution of an explosion close to the stellar surface, and give predictions for the radiation from such an event. We show that such an event will give ri…
Nekhoroshev Estimates for the Survival Time of Tightly Packed Planetary Systems
Almog Yalinewich, Cristobal Petrovich
-body simulations of non-resonant tightly-packed planetary systems have found that their survival time (i.e. time to first close encounter) grows exponentially with their interp…
Fast Radio Bursts from Terraformation
Almog Yalinewich, Mubdi Rahman, Alysa Obertas +1
Fast radio bursts (FRBs) are, as the name implies, short and intense pulses of radiation at wavelengths of roughly one metre. FRBs have extremely high brightness temperatures, whic…
Radio Emission from the unbound Debris of Tidal Disruption Events
Almog Yalinewich, Elad Steinberg, Tsvi Piran +1
When a star gets too close to a supermassive black hole, it is torn apart by the tidal forces. Roughly half of the stellar mass becomes unbound and flies away at tremendous velocit…
Statistical inference of the distance to ASKAP FRBs
Dongzi Li, Almog Yalinewich, Patrick C. Breysse
The distances to fast radio bursts (FRBs) are crucial for understanding their underlying engine, and for their use as cosmological probes. In this paper, we provide three statistic…
Atmospheric Mass Loss from High Velocity Giant Impacts
Almog Yalinewich, Hilke E. Schlichting
Using moving mesh hydrodynamic simulations, we determine the shock propagation and resulting ground velocities for a planet hit by a high velocity impactor. We use our results to d…
The Signature of a Windy Radio Supernova Progenitor in a Binary System
Almog Yalinewich, Simon Portegies Zwart
Type II supernova progenitors are expected to emit copious amounts of mass in a dense stellar wind prior to the explosion. When the progenitor is a member of a binary, the orbital…
Shock Breakouts from Tidal Disruption Events
Almog Yalinewich, James Guillochon, Re'em Sari +1
Tidal disruption events of stars by supermassive black holes have so far been discovered months to years after the fact. In this paper we explore the short, faint and hard burst of…
Dark Passengers in Stellar Surveys
Almog Yalinewich, Paz Beniamini, Kenta Hotokezaka +1
We develop stellar population models to predict the number of binaries with a single luminous member is Gaia and Hipparcos. Our models yield dozens of detections of black hole - lu…
Ignition of detonation in accreted helium
Ami Glasner, Eli Livne, Elad Steinberg +2
Sub-Chandrasekhar CO white dwarfs accreting helium have been considered as candidates for Type Ia supernova(SNIa) progenitors since the early 1980s (helium shell mass $> 0.1 M_\odo…
Supernovae generated High Velocity Compact Clouds
Almog Yalinewich, Paz Beniamini
It has been proposed that an intermediate mass black hole can produce compact molecular clouds with large velocity dispersions. This model is called into question due to the discov…
Evolution of Supernova Remnants near the Galactic Center
Almog Yalinewich, Tsvi Piran, Re'em Sari
Supernovae near the galactic center evolve differently from regular galactic supernovae. This is mainly due to the environment into which the supernova remnants propagate. Instead…
Analytic Asymptotic Solution to Spherical Relativistic Shock Breakout
Almog Yalinewich, Re'em Sari
We investigate the relativistic breakout of a shock wave from the surface of a star. In this process, each fluid shell is endowed with some kinetic and thermal energy by the shock,…
Grid Noise in Moving Mesh Codes: Fixing The Volume Inconsistency Problem
Elad Steinberg, Almog Yalinewich, Re'em Sari
Current Voronoi based moving mesh hydro codes suffer from "grid noise". We identify the cause of this noise as the volume inconsistency error, where the volume that is transferred…
Asymptotic Steady State Solution to a Bow Shock with an Infinite Mach Number
Almog Yalinewich, Re'em Sari
The problem of a cold gas flowing past a stationary object is considered. It is shown that at large distances from the obstacle the shock front forms a parabolic solid of revolutio…
Rich: Open Source Hydrodynamic Simulation on a Moving Voronoi Mesh
Almog Yalinewich, Elad Steinberg, Re'em Sari
We present here RICH, a state of the art 2D hydrodynamic code based on Godunov's method, on an unstructured moving mesh (the acronym stands for Racah Institute Computational Hydrod…
Balancing the load: A Voronoi based scheme for parallel computations
Elad Steinberg, Almog Yalinewich, Re'em Sari +1
The use of numerical simulations in science is ever increasing and with it the computational size. In many cases single processors are no longer adequate and simulations are run on…
