Quasi-periodic flares in EXO 2030+375 observed with INTEGRAL
D. Klochkov, C. Ferrigno, A. Santangelo +5
Context: Episodic flaring activity is a common feature of X-ray pulsars in HMXBs. In some Be/X-ray binaries flares were observed in quiescence or prior to outbursts. EXO 2030+375 i…
The discovery of the 401 Hz accreting millisecond pulsar IGR J17498-2921 in a 3.8 hr orbit
A. Papitto, E. Bozzo, C. Ferrigno +6
We report on the detection of a 400.99018734(1) Hz coherent signal in the Rossi X-ray Timing Explorer light curves of the recently discovered X-ray transient, IGR J17498-2921. By a…
Pulse-amplitude-resolved spectroscopy of bright accreting pulsars: indication of two accretion regimes
D. Klochkov, R. Staubert, A. Santangelo +2
Context: In addition to coherent pulsation, many accreting neutron stars exhibit flaring activity and strong aperiodic variability on time scales comparable to or shorter than thei…
4U 0115+63: phase lags and cyclotron resonant scattering
C. Ferrigno, M. Falanga, E. Bozzo +3
High mass X-ray binaries are among the brightest objects of our Galaxy in the high energy domain (0.1-100 keV). Despite our relatively good knowledge of their basic emission mechan…
XMM-Newton observations of IGRJ18410-0535: The ingestion of a clump by a supergiant fast X-ray transient
E. Bozzo, A. Giunta, G. Cusumano +6
IGRJ18410-0535 is a supergiant fast X-ray transients. This subclass of supergiant X-ray binaries typically undergoes few- hour-long outbursts reaching luminosities of 10^(36)-10^(3…
