Suzaku spectra of a Type II Supernova Remnant Kes 79
Tamotsu Sato, Katsuji Koyama, Shiu-Hang Lee +1
This paper reports results of a Suzaku observation of the supernova remnant (SNR) Kes 79 (G33.6+0.1). The X-ray spectrum is best fitted by a two-temperature model: a non-equilibriu…
Evidence for Thermal X-Ray Line Emission from the Synchrotron-Dominated Supernova Remnant RX J1713.7-3946
Satoru Katsuda, Fabio Acero, Nozomu Tominaga +14
We report the first detection of thermal X-ray line emission from the supernova remnant (SNR) RX J1713.7-3946, the prototype of the small class of synchrotron dominated SNRs. A sof…
Simulating Cherenkov Telescope Array observation of RX J1713.7-3946
T. Nakamori, H. Katagiri, H. Sano +29
We perform simulations of Cherenkov Telescope Array (CTA) observations of a young supernova remnant RX J1713.7-3946. This target is not only one of the brightest sources ever disco…
Matter Mixing in Core-collapse Supernova Ejecta: Large Density Perturbations in the Progenitor Star?
J. Mao, M. Ono, S. Nagataki +5
Matter mixing is one important topic in the study of core-collapse supernova (CCSN) explosions. In this paper, we perform two-dimensional hydrodynamic simulations to reproduce the…
Electron and Ion Acceleration in Relativistic Shocks with Applications to GRB Afterglows
Donald C. Warren, Donald C. Ellison, Andrei M. Bykov +1
We have modeled the simultaneous first-order Fermi shock acceleration of protons, electrons, and helium nuclei by relativistic shocks. By parameterizing the particle diffusion, our…
Modeling Bright Gamma-ray and Radio Emission at Fast Cloud Shocks
Shiu-Hang Lee, Daniel J. Patnaude, John C. Raymond +3
Recent observations by the Large Area Telescope (LAT) onboard the Fermi satellite have revealed bright gamma-ray emission from middle-aged supernova remnants (SNRs) inside our Gala…
Are Models for Core-Collapse Supernova Progenitors Consistent with the Properties of Supernova Remnants?
Daniel J. Patnaude, Shiu-Hang Lee, Patrick O. Slane +4
The recent discovery that the Fe-K line luminosities and energy centroids observed in nearby SNRs are a strong discriminant of both progenitor type and circumstellar environment ha…
