A Self-regulated Stochastic Acceleration Model of Pulsar Wind Nebulae
Shuta J. Tanaka, Wataru Ishizaki
Pulsar wind nebulae (PWNe) are clouds of the magnetized relativistic electron/positron plasma supplied from the central pulsar. However, the number of radio-emitting particles insi…
Direct Measurement of the Nickel Spectrum in Cosmic Rays in the Energy Range from 8.8 GeV/n to 240 GeV/n with CALET on the International Space Station
O. Adriani, Y. Akaike, K. Asano +78
The relative abundance of cosmic ray nickel nuclei with respect to iron is by far larger than for all other trans-iron elements, therefore it provides a favorable opportunity for a…
Detection of gamma rays around SNR HB9 and its implication to the diffusive shock-acceleration history
Tomohiko Oka, Wataru Ishizaki
We analyze the GeV gamma-ray emission data from the vicinity of the supernova remnant (SNR) HB9 (G160.9+2.6) from the \textit{Fermi}-LAT 12-year observations to quantify the evolut…
A Comprehensive Study of the Spectral Variation and the Brightness Profile of Young Pulsar Wind Nebulae
Chin-Ping Hu, Wataru Ishizaki, C. -Y. Ng +2
We present a systematic study of particle transport by diffusion in young pulsar wind nebulae (PWNe). We selected nine bright sources that are well resolved with the Chandra X-ray…
Measurement of the Iron Spectrum in Cosmic Rays from 10 GeV to 2.0 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +77
The Calorimetric Electron Telescope (CALET), in operation on the International Space Station since 2015, collected a large sample of cosmic-ray iron over a wide energy interval. In…
Fallback Accretion Model for the Years-to-Decades X-ray Counterpart to GW170817
Wataru Ishizaki, Kunihito Ioka, Kenta Kiuchi
A new component was reported in the X-ray counterpart to the binary neutron-star merger and gravitational wave event GW170817, exceeding the afterglow emission from an off-axis str…
