Obtaining the diffusion coefficient for cosmic ray propagation in the Galactic Centre Ridge through time-dependent simulations of their gamma-ray emission
Stavros Dimitrakoudis, Apostolos Mastichiadis, Athanasios Geranios
Recent observations by the H.E.S.S. collaboration of the Galactic Centre region have revealed what appears to be gamma-ray emission from the decay of pions produced by interactions…
On the rapid TeV flaring activity of Markarian 501
A. Mastichiadis, K. Moraitis
Aims: We investigate the one-zone SSC model of TeV blazars in the presence of electron acceleration. In this picture electrons reach a maximum energy where acceleration saturates f…
Simulation of Cosmic Ray propagation in the Galactic Centre Ridge in Accordance with Observed VHE gamma-ray Emission
S. Dimitrakoudis, A. Mastichiadis, A. Geranios
Diffuse VHE gamma radiation from the Galactic Centre ridge observed by the H.E.S.S. telescope has been convincingly linked with the propagation of recently accelerated cosmic rays…
Compton dragged supercritical piles: The GRB prompt and afterglow scenario
A. Mastichiadis, D. Kazanas
We examine the prompt and afterglow emission within the context of the Supercritical Pile model for GRBs. For this we have performed self-consistent calculations, by solving three…
Efficiency limits of diffusive shock acceleration
A. Meli, A. Mastichiadis
It is well accepted today that diffusive acceleration in shocks results to the cosmic ray spectrum formation. This is in principle true for non-relativistic shocks, since there is…
The "Supercritical Pile" GRB Model: Afterglows and GRB, XRR, XRF Unification
Demosthenes Kazanas, Apostolos Mastichiadis, Markos Georganopoulos
We present the general notions and observational consequences of the "Supercritical Pile" GRB model; the fundamental feature of this model is a detailed process for the conversion…
