Spectral and timing properties of IGR J00291+5934 during its 2015 outburst
A. Sanna, F. Pintore, E. Bozzo +8
We report on the spectral and timing properties of the accreting millisecond X-ray pulsar IGR J00291+5934 observed by XMM-Newton and NuSTAR during its 2015 outburst. The source is…
Discovery of a soft X-ray 8 mHz QPO from the accreting millisecond pulsar IGR J00291+5934
C. Ferrigno, E. Bozzo, A. Sanna +7
In this paper, we report on the analysis of the peculiar X-ray variability displayed by the accreting millisecond X-ray pulsar IGR J00291+5934 in a 80 ks-long joint NuSTAR and XMM-…
Study of the reflection spectrum of the LMXB 4U 1702-429
R. Iaria, T. Di Salvo, M. Del Santo +7
The source 4U 1702-429 (Ara X-1) is a low-mass X-ray binary system hosting a neutron star. Albeit the source is quite bright ( erg s) its broadband spectrum ha…
Discovery of hard phase lags in the pulsed emission of GRO J1744-28
Antonino D'Aì, Luciano Burderi, Tiziana Di Salvo +4
We report on the discovery and energy dependence of hard phase lags in the 2.14 Hz pulsed profiles of GRO J1744-28. We used data from XMM-Newton and NuSTAR. We were able to well co…
A new investigation of the possible X-ray counterparts of the magnetar candidate AX J1845-0258
Fabio Pintore, Sandro Mereghetti
AX J1845-0258 is a transient X-ray pulsar, with spin period of 6.97s, discovered with the ASCA satellite in 1993. Its soft spectrum and the possible association with a supernova re…
The ultraluminous X-ray source NGC 5643 ULX1: a large stellar mass black hole accreting at super-Eddington rates?
F. Pintore, L. Zampieri, A. D. Sutton +3
A sub-set of the brightest ultraluminous X-ray sources (ULXs), with X-ray luminosities well above erg s, typically have energy spectra which can be well described…
