We have investigated electromagnetic (EM) wave pulses in a jet from a neutrino-driven accretion flow (NDAF) around a black hole (BH). NDAFs are massive accretion disks whose accretion rates are Ṁ≈ 0.01–10 M ⊙ s−1 for stellar-mass BHs. Such an extreme accretion may produce a collimated relativistic outflow like a magnetically driven jet in active galactic nuclei and microquasars. When we consider strong toroidal magnetic field stranded in the inner region of an NDAF disk and magnetic impulses…

Production of intense episodic Alfvén pulses: GRMHD simulation of black hole accretion discs

The episodic dynamics of the magnetic eruption of a spinning black hole (BH) accretion disks and its associated intense shapeup of their jets is studied via three-dimensional general-relativistic

Magnetar-Driven Magnetic Tower as a Model for Gamma-Ray Bursts and Asymmetric Supernovae

We consider a newly born millisecond magnetar, focusing on its interaction with the dense stellar plasma in which it is initially embedded. We argue that the confining pressure and inertia of the

Gamma-ray bursts from stellar mass accretion disks around black holes

A cosmological model for gamma-ray bursts is explored in which the radiation is produced as a broadly beamed pair fireball along the rotation axis of an accreting black hole. The black hole may be a

Magnetohydrodynamic Accretion Flows: Formation of Magnetic Tower Jet and Subsequent Quasi-Steady State

We present three-dimensional magnetohydrodynamic (MHD) simulations of radiatively inefficient accretion flow around black holes. General relativistic effects are simulated by using the

Evolution of a neutrino-cooled disc in gamma-ray bursts

Rapid, hyper-Eddington accretion is likely to power the central engines of gamma-ray bursts (GRBs). In the extreme conditions of densities and temperatures the accreting torus is cooled by neutrino

Stellar Explosions by Magnetic Towers

We propose a magnetic mechanism for the collimated explosion of massive stars relevant for long-duration gamma-ray bursts (GRBs), X-ray flashes (XRFs), and asymmetric core collapse supernovae. In

Effect of a Magneto-Rotational Instability on Jets from Accretion Disks

We present the results of 2.5-dimensional MHD simulations of jet formation from accretion disks that are unstable for a magneto-rotational instability. Numerical simulations show that magnetically

Collapsars: Gamma-Ray Bursts and Explosions in “Failed Supernovae”

Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα ≳ 10 M☉, in which iron-core collapse does not produce a successful outgoing
