Non-thermal Emissions from Cool Cores Heated by Cosmic-Rays in Galaxy Clusters
Yutaka Fujita, Yutaka Ohira
We study non-thermal emissions from cool cores in galaxy clusters. We adopted a recent model, in which cosmic-rays (CRs) prevail in the cores and stably heat them through CR stream…
Stable Heating of Cluster Cooling Flows by Cosmic-Ray Streaming
Yutaka Fujita, Yutaka Ohira
We study heating of cool cores in galaxy clusters by cosmic-ray (CR) streaming using numerical simulations. In this model, CRs are injected by the central active galactic nucleus (…
Star Formation in the Cometary Tails Associated with Cluster Galaxies
Takahiro Yamagami, Yutaka Fujita
We investigate the star-formation in cometary tails of galaxies in clusters. In particular, we focus on the evolution of molecular clouds in the tails that generate the stars. Assu…
Alfven Wave Amplification and Self-Containment of Cosmic-Rays Escaping from a Supernova Remnant
Yutaka Fujita, Fumio Takahara, Yutaka Ohira +1
We study the escape of cosmic-ray (CR) protons accelerated at a supernova remnant (SNR) by numerically solving a diffusion-convection equation from the vicinity of the shock front…
