The interstellar medium is not necessary fully ionized. When a shock propagates into the partially ionized medium, some neutral particles leak into the upstream region from the downstream region. In t...

Aims. We study the chemistry in the harsh environments of galactic nuclei using the nearest one, the Galactic center (GC).Methods. We have obtained maps of the molecular emission within the central fi...
The Role of Diffusive Shock Acceleration on Nonequilibrium Ionization in Supernova Remnant Shocks II: Emitted Spectra
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
We present a grid of nonequilibrium ionization models for the X-ray spectra from supernova remnants undergoing efficient diffusive shock acceleration. The calculation follows the hydrodynamics of the ...
Computation of synthetic spectra from simulations of relativistic shocks

2010/12/24
Particle-in-cell (PIC) simulations of relativistic shocks are in principle capable of predicting the spectra of photons that are radiated incoherently by the accelerated particles. The most direct met...
Cosmic-ray current driven turbulence in shocks with efficient particle acceleration: the oblique, long-wavelength mode instability

In order for diffusive shock acceleration (DSA) to accelerate particles to high energies, the energetic particles must be able to interact with magnetic turbulence over a broad wavelength range.
The spectrum of Cosmic Rays escaping from relativistic shocks
Cosmic Rays relativistic shocks
2010/3/8
We derive expressions for the time integrated spectrum of Cosmic Rays (CRs) that are accelerated in a decelerating relativistic shock wave and escape ahead of the shock. It is assumed that at any give...

2009/5/19
Accretion shocks are known to oscillate in presence of cooling
processes in the disk. This oscillation may also cause quasi-periodic
oscillations of black holes. In the presence of strong winds, the...

We self-consistently obtain shock locations in an accretion
flow by using an analytical method. One can obtain the spectral properties,
quasi-periodic oscillation frequencies and the outflowrates wh...
