In the absence of magnetic fields and cosmic rays, radiative cooling laws with a range of dependences on
temperature affect the stability of interstellar gas. For about four and a half decades, astrophysicists have
recognised the importance of the thermal instability for the formation of clouds in the interstellar medium.
Even in the past several years, many papers have concerned the role...

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 to the region far away from the front. We consider the amplifications of Alfven waves generated by the escaping CR particles and their effects on CR escape into interstellar medium (ISM). We find that the...

Equipartition or the minimum-energy calculation is a widespread method for
estimating magnetic field strength and energy in the magnetic field and cosmic rays particles
by using only the radio synchrotron emission. Despite of its approximate character,
it remains a useful tool in situations when no other data about the source are available. We give a modified calculation which we think is...

We overview recent progress on small-scale dynamo and apply
the results to the the problem of nonlinear shock acceleration in which
particle mean free paths in front of the shock are greatly reduced
due to magnetic fields in the shock precursor which are generated
through small-scale dynamo in the density gradient's-induced
turbulence. Previous DSA models considered magnetic fields...
