The nature of the X-ray transient MAXI J0556-332
R. Cornelisse, P. D'Avanzo, S. Campana +8
Phase-resolved spectroscopy of the newly discovered X-ray transient MAXI J0556-332 has revealed the presence of narrow emission lines in the Bowen region that most likely arise on…
Emission geometry, radiation pattern, and magnetic topology of the magnetar XTE J1810-197 in its quiescent state
Federico Bernardini, Rosalba Perna, Eric Gotthelf +3
The return to the quiescent state of the Anomalous X-ray pulsar XTE J1810-197 following its 2003 outburst represents a unique opportunity to probe the surface emission properties o…
XMM-Newton observations of the supergiant fast X-ray transients XTEJ1739-302, IGRJ08408-4503 and IGRJ18410-0535
E. Bozzo, C. Ferrigno, J. C. Leyder +5
We report here on the XMM-Newton observations of the three supergiant fast X-ray transients (SFXT) XTE J1739-302, IGRJ08408-4503, and IGRJ18410-0535. For the latter source we only…
Study of the X-ray/gamma source AX J1910.7+0917 and three newly discovered INTEGRAL sources
L. Pavan, E. Bozzo, C. Ferrigno +4
AX J1910.7+0917 is a still unidentified source discovered with ASCA and observed more recently with IBIS/ISGRI, mainly noticeable for its rather hard spectrum. We analyzed all the…
X-ray bursts and burst oscillations from the slowly spinning X-ray pulsar IGR J17480-2446 (Terzan 5)
S. Motta, A. D'Aì, A. Papitto +5
The newly discovered 11 Hz accreting pulsar, IGR J17480-2446, located in the globular cluster Terzan 5, has shown several bursts with a recurrence time as short as few minutes. The…
