DESCRIPTION:Speakers: Ryosuke Kobashi ()\nSupernova remnants (SNRs) have b
 een considered as the sources of the bulk of Galactic cosmic-ray (CR). Rec
 ently some evidences of extended gamma-ray emission are reported by e.g. L
 HAASO and H.E.S.S. and this emission infers the existence of particles esc
 aping from accelerating region of SNRs. \nIn this work\, we solve one-dime
 nsional diffusion-convection equation coupled with analytical solutions fo
 r shock dynamics\, to obtain the time evolution of phase-space distributio
 n function of CR. As a result\, the time evolution of CR acceleration stil
 l increases even after the age of 10kyrs in our models\, and this behavior
  is largely affected by environment of SNRs.\n\nhttps://indico.icrr.u-toky
