The explosion jets of the core-collapse supernova remnant Circinus X-1

Noam Soker, Muhammad Akashi

We propose that the recently analyzed opposite rings in the Circinus X-1 (Cir X-1) core collapse supernova (CCSN) remnant resulted from a pair of opposite jets at the final phases…

Jet-Driven Formation of Bipolar Rings in Planetary Nebulae: Numerical Simulations Inspired by NGC 1514

Muhammad Akashi, Ealeal Bear, Noam Soker

We conduct three-dimensional hydrodynamical simulations of jets launched into a dense shell, reproducing two rings in a bipolar structure that resemble the two dusty rings of the p…

Simulating the shaping of point-symmetric structures in the jittering jets explosion mechanism

Jessica Braudo, Amir Michaelis, Muhammad Akashi +1

We conduct three-dimensional hydrodynamical simulations of core-collapse supernovae by launching several pairs of jets into a collapsing core model and show that the jittering jets…

Rapid decline in the lightcurves of luminous supernovae by jet-driven bipolar explosions

Muhammad Akashi, Amir Michaelis, Noam Soker

We calculate the lightcurves of jet-driven bipolar core collapse supernova (CCSN) explosions into a bipolar circumstellar mater (CSM) and show that an equatorial observer finds the…

Post-explosion positive jet-feedback activity in inner ejecta of core collapse supernovae

Muhammad Akashi, Noam Soker

We conduct three-dimensional hydrodynamical simulations of weak jets that we launch into a core collapse supernovae (CCSNe) ejecta half an hour after the explosion and find that th…

Simulating the outcome of binary neutron star merger in common envelope jets supernovae

Muhammad Akashi, Noam Soker

We simulate the influence of the energy that the merger process of two neutron stars (NSs) releases inside a red supergiant (RSG) star on the RSG envelope inner to the merger locat…

Shaping `Ears' in planetary nebulae by early jets

Muhammad Akashi, Noam Soker

We conduct three dimensional hydrodynamical numerical simulations of planetary nebula (PN) shaping and show that jets that precede the ejection of the main PN shell can form the mo…

Simulating jets from a neutron star companion hours after a core collapse supernova

Muhammad Akashi, Noam Soker

We conduct three-dimensional hydrodynamical simulations to explore the interaction of jets that a neutron star (NS) companion to a type Ic or type Ib core collapse supernova (CCSN)…

Observers, observations and referencing in physics theories

Uri Ben-Ya'acov

Is it possible to encompass the full extent of the universe within a theory based on a finite set of first principles and inference rules? The rôle of observers and observations in…

Simulating the inflation of bubbles by late jets in core collapse supernova ejecta

Muhammad Akashi, Noam Soker

We conducted three-dimensional hydrodynamical simulations to study the interaction of two late opposite jets with the ejecta of a core collapse supernova (CCSN), and study the bipo…

Fast Ejecta Resulted from Jet-Wind Interaction in the Great Eruption of Eta Carinae

Muhammad Akashi, Amit Kashi

The accretion model for the nineteenth century Great Eruption (GE) of Carinae suggests that mass outflowing from the primary was accreted onto the secondary, and the gravitatio…

WSEmail: A Retrospective on a System for Secure Internet Messaging Based on Web Services

Michael J. May, Kevin D. Lux, Carl A. Gunter

Web services offer an opportunity to redesign a variety of older systems to exploit the advantages of a flexible, extensible, secure set of standards. In this work we revisit WSEma…

Gödel's incompleteness theorem and universal physics theories

Uri Ben-Ya'acov

An ultimate universal theory -- a complete theory that accounts, via few and simple first principles, for all the phenomena already observed and that will ever be observed -- has b…

The formation of `columns crowns' by jets interacting with a circumstellar dense shell

Muhammad Akashi, Noam Soker

We conduct three-dimensional hydrodynamical simulations of two opposite jets that interact with a spherical slow wind that includes a denser shell embedded within it, and obtain a…

Back to epicycles - relativistic Coulomb systems in velocity space

Uri Ben-Ya'acov

The study of relativistic Coulomb systems in velocity space is prompted by the fact that the study of Newtonian Kepler/Coulomb systems in velocity space, although less familiar tha…

One more (a further) generalization of the Final Value Theorem

Emanuel Gluskin, Shmuel Miller, Joris Walraevens

It is shown that the previous [1-3] generalization of the final-value theorem to the average (not necessarily limiting) values, can be extended to the higher-order running averages…

On the recovery of the time average of continuous and discrete time functions from their Laplace and z-transforms

Emanuel Gluskin, Shmuel Miller

The determination of the time averages of continuous functions, or discrete time sequences is important for various problems in physics and engineering, and the generalized final-v…

Centre-of-mass and internal symmetries in classical relativistic systems

Uri Ben-Ya'acov

The internal symmetry of composite relativistic systems is discussed. It is demonstrated that Lorentz-Poincaré symmetry implies the existence of internal moments associated with th…

Laplace-Runge-Lenz symmetry in general rotationally symmetric systems

Uri Ben-Ya'acov

The universality of the Laplace-Runge-Lenz symmetry in all rotationally symmetric systems is discussed. The independence of the symmetry on the type of interaction is proven using…
