Contribution of Type Ia and Type II Supernovae to Intracluster Medium Enrichment
- S. Nagataki, Katsuhiko Sato
- Physics
- 2 July 1998
The origin of the chemical composition of the intracluster medium (ICM) is discussed in this paper. In particular, the contribution from Type Ia supernovae (SNe Ia) to the ICM enrichment is…
Effects of Jetlike Explosion in SN 1987A
- S. Nagataki
- Physics
- 8 July 1999
We study the effects of jetlike explosion in SN 1987A. Calculations of the explosive nucleosynthesis and the matter mixing in a jetlike explosion are performed, and their results are compared with…
High-energy cosmic-ray nuclei from high- and low-luminosity gamma-ray bursts and implications for multimessenger astronomy
- K. Murase, K. Ioka, S. Nagataki, Takashi Nakamura
- Physics
- 18 January 2008
Gamma-ray bursts (GRBs) are one of the candidates of ultrahigh-energy ($\ensuremath{\gtrsim}{10}^{18.5}\text{ }\text{ }\mathrm{eV}$) cosmic-ray (UHECR) sources. We investigate high-energy cosmic-ray…
Extended monopole solution of the Blandford-Znajek mechanism: Higher order terms for a Kerr parameter
- Kentaro Tanabe, S. Nagataki
- Physics
- 3 July 2008
The Blandford-Znajek mechanism, by which the rotational energy of a black hole is extracted through electromagnetic fields, is one of the promising candidates as an essential process of the central…
High energy neutrino emission and neutrino background from gamma-ray bursts in the internal shock model
- K. Murase, S. Nagataki
- Physics
- 12 December 2005
High energy neutrino emission from gamma-ray bursts (GRBs) is discussed. In this paper, by using the simulation kit GEANT4, we calculate proton cooling efficiency including pion-multiplicity and…
A GENERALIZED MODEL OF NONLINEAR DIFFUSIVE SHOCK ACCELERATION COUPLED TO AN EVOLVING SUPERNOVA REMNANT
- Shiu-Hang Lee, D. Ellison, S. Nagataki
- Physics
- 16 March 2012
To better model the efficient production of cosmic rays (CRs) in supernova remnants (SNRs) with the associated coupling between CR production and SNR dynamics, we have generalized an existing…
