Production of intense episodic Alfvén pulses: GRMHD simulation of black hole accretion disks
Akira Mizuta, Toshikazu Ebisuzaki, Toshiki Tajima +1
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 gener…
Spectral and Polarization Properties of Photospheric Emission From Stratified Jets
Hirotaka Ito, Shigehiro Nagataki, Jin Matsumoto +5
We explore the spectral and polarization properties of photospheric emissions from stratified jets in which multiple components, separated by a sharp velocity shear regions, are di…
Photospheric emission from stratified jets
Hirotaka Ito, Shigehiro Nagataki, Masaomi Ono +6
We explore photospheric emissions from stratified two-component jets, wherein a highly relativistic spine outflow is surrounded by a wider and less relativistic sheath outflow. The…
Opening Angles of Collapsar Jets
Akira Mizuta, Kunihito Ioka
We investigate the jet propagation and breakout from the stellar progenitor for gamma-ray burst (GRB) collapsars by performing two-dimensional relativistic hydrodynamic simulations…
Gamma-Ray Burst without Baryonic and Magnetic Load?
Kunihito Ioka, Yutaka Ohira, Norita Kawanaka +1
We show that, contrary to common belief, internal shocks can arise in an accelerating radiation-dominated jet if it is confined even weakly to a converging opening angle because th…
Thermal Radiation from GRB Jets
Akira Mizuta, Shigehiro Nagataki, Junichi Aoi
In this study, the light curves and spectrum of the photospheric thermal radiation from ultrarelativistic gamma-ray burst (GRB) jets are calculated using 2D relativistic hydrodynam…
