Two-Stage Regularization of Pseudo-Likelihood Estimators with Application to Time Series
Erez Buchweitz, Shlomo Ahal, Oded Papish +1
Estimators derived from score functions that are not the likelihood are in wide use in practical and modern applications. Their regularization is often carried by pseudo-posterior…
Explaining the most energetic supernovae with an inefficient jet-feedback mechanism
Avishai Gilkis, Noam Soker, Oded Papish
We suggest that the energetic radiation from core-collapse super-energetic supernovae (SESNe) is due to a long lasting accretion process onto the newly born neutron star (NS), resu…
Jittering-jets explosion triggered by the standing accretion shock instability
Oded Papish, Avishai Gilkis, Noam Soker
We show that the standing accretion shock instability (SASI) that has been used to ease the shock revival in core collapse supernovae (CCSNe) neutrino-driven explosion models, migh…
Supernovae from direct collisions of white dwarfs and the role of helium shell ignition
Oded Papish, Hagai B. Perets
Models for supernovae (SNe) arising from thermonuclear explosions of white dwarfs (WDs) have been extensively studied over the last few decades, mostly focusing on the single degen…
The response of a helium white dwarf to an exploding type Ia supernova
Oded Papish, Noam Soker, Enrique García-Berro +1
We conduct numerical simulations of the interacting ejecta from an exploding CO white dwarf (WD) with a He WD donor in the double-detonation scenario for Type Ia supernovae (SNe Ia…
A Planar Jitternig-Jets Pattern in Core-Collapse Supernova Explosions
Oded Papish, Noam Soker
We use 3D hydrodynamical numerical simulations and show that jittering bipolar jets that power core-collapse supernova (CCSN) explosions channel further accretion onto the newly bo…
A call for a paradigm shift from neutrino-driven to jet-driven core-collapse supernova mechanisms
Oded Papish, Jason Nordhaus, Noam Soker
Three-dimensional (3D) simulations in recent years have shown severe difficulties producing 10^51 erg explosions of massive stars with neutrino based mechanisms while on the other…
Ejecting the envelope of red supergiant stars with jets launched by an inspiraling neutron star
Oded Papish, Noam Soker, Inbal Bukay
We study the properties of jets launched by a neutron star spiralling inside the envelope and core of a red supergiant. We propose that Thorne-Zytkow objects (TZO) are unlikely to…
Exploding Core-Collapse Supernovae by Jets-Driven Feedback Mechanism
Oded Papish, Noam Soker
We study the flow structure in the jittering-jets explosion model of core-collapse supernovae (CCSNe) using 2.5D hydrodynamical simulations and find that some basic requirements fo…
The jet feedback mechanism (JFM): from supernovae to clusters of galaxies
Noam Soker, Muhammad Akashi, Avishai Gilkis +4
We study the similarities of jet-medium interactions in several quite different astrophysical systems using 2D and 3D hydrodynamical numerical simulations, and find many similariti…
Exploding SNe with jets: time-scales
Oded Papish, Noam Soker
We perform hydrodynamical simulations of core collapse supernovae (CCSNe) with a cylindrically-symmetrical numerical code (FLASH) to study the inflation of bubbles and the initiati…
Nucleosynthesis of r-Process Elements by Jittering Jets in Core-Collapse Supernovae
Oded Papish, Noam Soker
We calculate the nucleosynthesis inside the hot bubble formed in the jittering-jets model for core collapse supernovae (CCSNe) explosions, and find the formation of several times 1…
Exploding Core-Collapse Supernovae with Jittering Jets
Oded Papish, Noam Soker
We argue that jittering jets, i.e., jets that have their launching direction rapidly change, launched by the newly formed neutron star in a core collapse supernova can explode the…
