Particle acceleration in cooling flow clusters of galaxies: the case of Abell 2626
Myriam Gitti, Gianfranco Brunetti, Luigina Feretti +1
It has recently been proposed a theoretical model which accounts for the origin of radio mini-halos observed in some cooling flow clusters as related to electron re-acceleration by…
Supernova Statistics
Enrico Cappellaro, Roberto Barbon, Massimo Turatto
The statistics of SN discoveries is used to reveal selection biases of past and current SN searches and to gain insight on the progenitor scenarios for the different SN types. We a…
An XMM-Newton Study of the Hard X-ray Sky
E. Piconcelli, M. Cappi, L. Bassani +2
We report on the spectral properties of a sample of 90 hard X-ray selected serendipitous sources detected in 12 XMM observations with 1<F(2-10)<80 10^(-14) erg/cm2/s. Approximately…
Substructures in Cold Dark Matter Haloes
G. De Lucia, G. Kauffmann, V. Springel +5
We analyse the properties of substructures within dark matter halos (subhalos) using a set of high-resolution numerical simulations of the formation of structure in a Lambda-CDM Un…
Variable stars as tracers of stellar populations in Local Group galaxies: Leo I and NGC 6822
L. Baldacci, F. Matonti, L. Rizzi +5
Results are presented of a study of the variable star populations in the dwarf spheroidal galaxy Leo I and in the dwarf irregular galaxy NGC 6822, based on time series photometry o…
Building up the Galactic Halo: The Sagittarius dSph and the globular cluster M22
L. Monaco, F. R. Ferraro, M. Bellazzini +1
The Sagittarius dwarf spheroidal (Sgr) and a few paculiar Galactic Globular Clusters (GGC) can be considered as building blocks of theGalactic Halo. We present a series of results…
