The slowest spinning X-ray pulsar in an extragalactic globular cluster
Ivan Zolotukhin, Matteo Bachetti, Nicola Sartore +2
Neutron stars are thought to be born rapidly rotating and then exhibit a phase of a rotation-powered pulsations as they slow down to 1-10 s periods. The significant population of m…
The INTEGRAL/SPI view of A0535+26 during the giant outburst of February 2011
Nicola Sartore, Elisabeth Jourdain, Jean-Pierre Roques
A0535+26 is a slowly rotating pulsar accreting from the wind of a massive Be star, and that exhibits two cyclotron absorption lines in its X-ray spectrum, at about 45 and 100 keV,…
The ASTRI Mini-Array Science Case
S. Vercellone, G. Agnetta, L. A. Antonelli +77
ASTRI is a Flagship Project financed by the Italian Ministry of Education, University and Research, and led by INAF, the Italian National Institute of Astrophysics. Within this fra…
X-ray emission from the luminous O-type subdwarf HD 49798 and its compact companion
S. Mereghetti, N. La Palombara, A. Tiengo +4
The X-ray source RX J0648.0-4418 is the only confirmed binary system in which a compact object, most likely a massive white dwarf, accretes from a hot subdwarf companion, the brigh…
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…
PSR J0357+3205: a fast moving pulsar with a very unusual X-ray trail
A. De Luca, R. P. Mignani, M. Marelli +6
The middle-aged PSR J0357+3205 is a nearby, radio-quiet, bright gamma-ray pulsar discovered by the Fermi mission. Our previous Chandra observation revealed a huge, very peculiar st…
The birthplace and age of the isolated neutron star RX J1856.5-3754
R. P. Mignani, D. Vande Putte, M. Cropper +6
X-ray observations unveiled various types of radio-silent Isolated Neutron Stars (INSs), phenomenologically very diverse, e.g. the Myr old X-ray Dim INS (XDINSs) and the kyr old ma…
A study of the long term variability of RX J1856.5-3754 with XMM-Newton
S. Mereghetti, N. Sartore, A. Tiengo +3
We report on a detailed spectral analysis of all the available XMM-Newton data of RX J1856.5-3754, the brightest and most extensively observed nearby, thermally emitting neutron st…
Spectral monitoring of RX J1856.5-3754 with XMM-Newton. Analysis of EPIC-pn data
N. Sartore, A. Tiengo, S. Mereghetti +3
Using a large set of XMM-Newton observations we searched for long term spectral and flux variability of the isolated neutron star RX J1856.5-3754 in the time interval from April 20…
Matching microlensing events with X-ray sources
N. Sartore, A. Treves
The detection of old neutron stars and black holes in isolation is one of the cornerstones of compact object astrophysics. Microlensing surveys may help on this purpose since the l…
