    Minimal spanning tree algorithm for γ-ray source detection in sparse photon images: cluster parameters and selection strategies

    The minimal spanning tree (MST) algorithm is a graph-theoretical cluster-finding method. We previously applied it to γ-ray bidimensional images, showing that it is quite sensitive in finding faint sources. Possib...

    Diffusion and convection of relativistic electrons in non-thermal sources: Steady-state solutions

    In this paper we study the propagation of relativistic electrons in stationary spherically-symmetric models of non-thermal sources. Electrons are injected by a collapsed object in the centre and then diffuse a...
