The stochastic X-ray variability of the accreting millisecond pulsar MAXI J0911-655
Peter Bult
In this work I report on the stochastic X-ray variability of the 340 Hz accreting millisecond pulsar MAXI J0911-655. Analyzing pointed observations of the XMM-Newton and NuSTAR obs…
The aperiodic X-ray variability of the accreting millisecond pulsar SAX J1808.4-3658
Peter Bult, Michiel van der Klis
We have studied the aperiodic variability of the 401 Hz accreting millisecond X-ray pulsar SAX J1808.4-3658 using the complete data set collected with the Rossi X-ray Timing Explor…
A NICER thermonuclear burst from the millisecond X-ray pulsar SAX J1808.4-3658
Peter Bult, Gaurava K. Jaisawal, Tolga Güver +9
The Neutron Star Interior Composition Explorer (NICER) has extensively monitored the August 2019 outburst of the 401 Hz millisecond X-ray pulsar SAX J1808.4-3658. In this Letter, w…
Long-term coherent timing of the accreting millisecond pulsar IGR J17062-6143
Peter Bult, Tod E. Strohmayer, Christian Malacaria +2
We report on a coherent timing analysis of the 163 Hz accreting millisecond X-ray pulsar IGR J17062-6143. Using data collected with the Neutron Star Interior Composition Explorer a…
On the 2018 outburst of the accreting millisecond X-ray pulsar Swift J1756.9-2508 as seen with NICER
Peter Bult, Diego Altamirano, Zaven Arzoumanian +12
We report on the coherent timing analysis of the 182 Hz accreting millisecond X-ray pulsar Swift J1756.92508 during its 2018 outburst as observed with the Neutron Star Interior…
Thermonuclear X-ray Bursts with late secondary peaks observed from 4U 1608-52
Tolga Guver, Tugba Boztepe, Ersin Gogus +11
We report the temporal and spectral analysis of three thermonuclear X-ray bursts from 4U 1608-52, observed by the Neutron Star Interior Composition Explorer (NICER) during and just…
