Searching for small-scale diffuse emission around SGR 1806-20

D. Viganò, N. Rea, P. Esposito +6

Diffuse radio emission was detected around the soft gamma-ray repeater SGR 1806-20, after its 2004 powerful giant flare. We study the possible extended X-ray emission at small scal…

Neutron stars - thermal emitters

A. Y. Potekhin, A. De Luca, J. A. Pons

Confronting theoretical models with observations of thermal radiation emitted by neutron stars is one of the most important ways to understand the properties of both, superdense ma…

On the puzzling high-energy pulsations of the energetic radio-quiet -ray pulsar J18131246

M. Marelli, A. Harding, D. Pizzocaro +6

We have analyzed the new deep {\it XMM-Newton} and {\it Chandra} observations of the energetic radio-quiet pulsar J18131246. The X-ray spectrum is non-thermal, very hard and abs…

Identification of the TeV Gamma-ray Source ARGO J2031+4157 with the Cygnus Cocoon

YBJ Collaboration, B. Bartoli, P. Bernardini +80

The extended TeV gamma-ray source ARGO J2031+4157 (or MGRO J2031+41) is positionally consistent with the Cygnus Cocoon discovered by -LAT at GeV energies in the Cygnus super…

Photons to axion-like particles conversion in Active Galactic Nuclei

Fabrizio Tavecchio, Marco Roncadelli, Giorgio Galanti

The idea that photons can convert into axion-like particles (ALPs) in or around an AGN and reconvert back into photons in the Milky Way magnetic field has been p…

High-energy pulsations and phase-resolved spectroscopy of PSR J1741-2054

M. Marelli, A. Belfiore, P. Saz Parkinson +6

We report the results of a deep XMM-Newton observation of the radio-faint -ray pulsar J1741-2054 and its nebula together with the analysis of 5 years of Fermi LAT data. The X-ra…

Three new X-ray emitting sdO stars discovered with Chandra

N. La Palombara, P. Esposito, S. Mereghetti +1

X-ray observations of sdO stars are a useful tool to investigate their properties, but so far only two sdO stars were detected at X-rays. We observed a complete flux-limited sample…

The X-ray emission of the high mass X-ray binary IGR J17200-3116

P. Esposito, G. L. Israel, L. Sidoli +3

The source IGR J17200-3116 was discovered in the hard X-ray band by INTEGRAL. A periodic X-ray modulation at ~326 s was detected in its Swift light curves by our group (and subsequ…

Constraints on the winds of hot subdwarf stars from X-ray observations of two sdB binaries with compact companions: CD -30 11223 and PG 1232-136

S. Mereghetti, N. La Palombara, P. Esposito +5

Little observational data are available on the weak stellar winds of hot subdwarf stars of B spectral type (sdB). Close binary systems composed of an sdB star and a compact object…

Light-curve modelling constraints on the obliquities and aspect angles of the young Fermi pulsars

M. Pierbattista, A. K. Harding, I. A. Grenier +4

In more than four years of observation the Large Area Telescope on board the Fermi satellite has identified pulsed -ray emission from more than 80 young pulsars, providing light…

Energy Spectrum of Cosmic Protons and Helium Nuclei by a Hybrid Measurement at 4300 m a.s.l

B. Bartoli, P. Bernardini, X. J. Bi +97

The energy spectrum of cosmic Hydrogen and Helium nuclei has been measured, below the so-called "knee", by using a hybrid experiment with a wide field-of-view Cherenkov telescope a…
