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-…
Discovery of a new accreting millisecond X-ray pulsar in the globular cluster NGC 2808
A. Sanna, A. Papitto, L. Burderi +6
We report on the discovery of coherent pulsations at a period of 2.9 ms from the X-ray transient MAXI J0911-655 in the globular cluster NGC 2808. We observed X-ray pulsations at a…
The 2015 outburst of the accretion-powered pulsar IGR J00291+5934: INTEGRAL and Swift observations
V. De Falco, L. Kuiper, E. Bozzo +5
IGR J00291+5934 is the fastest-known accretion-powered X-ray pulsar, discovered during a transient outburst in 2004. In this paper, we report on Integral and Swift observations dur…
Multi-band study of RX J0838-2827 and XMM J083850.4-282759: a new asynchronous magnetic cataclysmic variable and a candidate transitional millisecond pulsar
N. Rea, F. Coti Zelati, P. Esposito +23
In search for the counterpart to the Fermi-LAT source 3FGL J0838.8-2829, we performed a multi-wavelength campaign, in the X-ray band with Swift and XMM-Newton, performed infrared,…
Near-periodical spin period evolution in the binary system LMC X-4
S. Molkov, A. Lutovinov, M. Falanga +2
In this paper we investigated the long-term evolution of the pulse-period in the high-mass X-ray binary LMC X-4 by taking advantage of more than 43~yrs of measurements in the X-ray…
