NGC 2276: a remarkable galaxy with a large number of ULXs
Anna Wolter, Paolo Esposito, Michela Mapelli +2
The starbusting, nearby (D = 32.9 Mpc) spiral (Sc) galaxy NGC2276 belongs to the sparse group dominated by the elliptical galaxy NGC2300. NGC2276 is a remarkable galaxy, as it disp…
PSR J0357+3205: the tail of the turtle
Martino Marelli, Andrea De Luca, David Salvetti +6
Using a new XMM-Newton observation, we have characterized the X-ray properties of the middle-aged radio-quiet gamma-ray pulsar J0357+3205 (named Morla) and its tail. The X-ray emis…
Stochastic accretion and the variability of supergiant fast X-ray transients
Fabio Pizzolato, Lara Sidoli
In this paper we consider the variability of the luminosity of a compact object (CO) powered by the accretion of an extremely inhomogeneous ("clumpy") stream of matter. The accreti…
A time-variable, phase-dependent emission line in the X-ray spectrum of the isolated neutron star RX J0822-4300
A. De Luca, D. Salvetti, A. Sartori +9
RX J0822-4300 is the Central Compact Object associated with the Puppis A supernova remnant. Previous X-ray observations suggested RX J0822-4300 to be a young neutron star with a we…
The XMM-Newton view of Supergiant Fast X-ray Transients: the case of IGRJ16418-4532
L. Sidoli, S. Mereghetti, V. Sguera +1
We report on a 40 ks long, uninterrupted X-ray observation of the candidate supergiant fast X-ray transient (SFXT) IGRJ16418-4532 performed with XMM-Newton on February 23, 2011. Th…
X-ray and optical observations of the unique binary system HD49798/RXJ0648.0-4418
S. Mereghetti, N. La Palombara, A. Tiengo +5
We report the results of XMM-Newton observations of HD49798/RXJ0648.0-4418, the only known X-ray binary consisting of a hot sub-dwarf and a white dwarf. The white dwarf rotates ver…
