Radio Mini-Halo Emission from Cosmic Rays in Galaxy Clusters and Heating of the Cool Cores
Yutaka Fujita, Yutaka Ohira
It has been proposed that the cool cores of galaxy clusters are stably heated by cosmic rays (CRs). If this is the case, radio mini-halos, which are often found in the central regi…
Observational signatures of particle acceleration in supernova remnants
E. A. Helder, J. Vink, A. M. Bykov +3
We evaluate the current status of supernova remnants as the sources of Galactic cosmic rays. We summarize observations of supernova remnants, covering the whole electromagnetic spe…
Gamma-ray flare and absorption in Crab Nebula: Lovely TeV-PeV astrophysics
Kazunori Kohri, Yutaka Ohira, Kunihito Ioka
We spectrally fit the GeV gamma-ray flares recently-observed in the Crab Nebula by considering a small blob Lorentz-boosted towards us. We point out that the corresponding inverse-…
Effects of Leakage Neutral Particles on Shocks
Yutaka Ohira
In this paper we investigate effects of neutral particles on shocks propagating into the partially ionized medium. We find that for 120 km/s < u_{sh} < 3000 km/s (u_{sh} is the sho…
