Low field magnetotransport in strained Si/SiGe cavities
G. Scappucci, L. Di Gaspare, F. Evangelisti +6
Low field magnetotransport revealing signatures of ballistic transport effects in strained Si/SiGe cavities is investigated. We fabricated strained Si/SiGe cavities by confining a…
A new reddening for RR Tel from the HeII Paschen lines
Pierluigi Selvelli, Piercarlo Bonifacio
From the available STIS data of RR Tel, that have provided a coverage with absolutely calibrated data in a wide wavelength range, we have obtained a new determination of its redden…
Astrocomp: a web service for the use of high performance computers in Astrophysics
U. Becciani, R. Capuzzo Dolcetta, A. Costa +3
Astrocomp is a joint project, developed by the INAF-Astrophysical Observatory of Catania, University of Roma La Sapienza and Enea. The project has the goal of providing the scienti…
The Distance to NGC 5904 (M 5) via the Subdwarfs Main Sequence Fitting Method
Vincenzo Testa, Alessandro Chieffi, Marco Limongi +2
We present a determination of the distance modulus of the globular cluster NGC 5904 (M 5), obtained by means of the subdwarf main-sequence fitting on the (V,V-I) color-magnitude di…
An XMM-Newton observation of Ark 120: the X-ray spectrum of a `bare' Seyfert 1 nucleus
S. Vaughan, A. C. Fabian, D. R. Ballantyne +3
We report on a long (100 ks) XMM-Newton observation of the bright Seyfert 1 galaxy Arakelian 120. The source previously showed no signs of intrinsic reddening in its infrared-ultra…
Elliptical galaxy nuclei activity powered by infalling globular clusters
R. Capuzzo-Dolcetta
Globular cluster systems evolve, in galaxies, due to internal and external dynamics and tidal phenomena. One of the causes of evolution, dynamical friction, is responsible for the…
