In-situ acceleration of subrelativistic electrons in the Coma halo and the halo's influence on the Sunyaev-Zeldovich effect
V. A. Dogiel, S. Colafrancesco, C. M. Ko +5
The stochastic acceleration of subrelativistic electrons from a background plasma is studied in order to find a possible explanation of the hard X-ray (HXR) emission detected from…
Detecting dark matter WIMPs in the Draco dwarf: a multi-wavelength perspective
S. Colafrancesco, S. Profumo, P. Ullio
We explore the possible signatures of dark matter (DM) pair annihilations in the nearby dwarf spheroidal galaxy Draco. After investigating the mass models for Draco in the light of…
Swift and infra-red observations of the blazar 3C~454.3 during the giant X-ray flare of May 2005
P. Giommi, A. J. Blustin, M. Capalbi +16
We present the results of a series of Swift and quasi simultaneous ground-based infra-red observations of the blazar 3C 454.3 carried out in April-May 2005 when the source was 10 t…
Non-thermal Cosmic Backgrounds and prospects for future high-energy observations of blazars
P. Giommi, S. Colafrancesco
We discuss the contribution of the blazar population to the extragalactic background radiation across the electromagnetic (e.m.) spectrum with particular reference to the microwave…
Comptonisation of Cosmic Microwave Background Photons in Dwarf Spheroidal Galaxies
Thomas L. Culverhouse, N. Wyn Evans, S. Colafrancesco
We present theoretical modelling of the electron distribution produced by annihilating neutralino dark matter in dwarf spheroidal galaxies (dSphs). In particular, we follow up the…
