NICER X-ray Observations of Seven Nearby Rotation-Powered Millisecond Pulsars
S. Guillot, M. Kerr, P. S. Ray +18
NICER observed several rotation-powered millisecond pulsars to search for or confirm the presence of X-ray pulsations. When broad and sine-like, these pulsations may indicate therm…
NuSTAR view of Be/X-ray binary pulsar 2S 1417-624 during 2018 giant outburst
Shivangi Gupta, Sachindra Naik, Gaurava K. Jaisawal
We report the results obtained from a detailed timing and spectral studies of Be/X-ray binary pulsar 2S 1417-624 using data from Swift and NuSTAR observatories. The observations we…
An evolving broad iron line from the first Galactic ultraluminous X-ray pulsar Swift J0243.6+6124
Gaurava K. Jaisawal, Colleen A. Wilson-Hodge, Andrew C. Fabian +15
We present a spectral study of the ultraluminous Be/X-ray transient pulsar Swift J0243.6+6124 using Neutron Star Interior Composition Explorer (NICER) observations during the syste…
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…
NICER observes a secondary peak in the decay of a thermonuclear burst from 4U 1608-52
Gaurava K. Jaisawal, Jérôme Chenevez, Peter Bult +14
We report for the first time below 1.5 keV, the detection of a secondary peak in an Eddington-limited thermonuclear X-ray burst observed by the Neutron Star Interior Composition Ex…
NICER Observation of Unusual Burst Oscillations in 4U 1728-34
Simin Mahmoodifar, Tod E. Strohmayer, Peter Bult +9
The Neutron Star Interior Composition Explorer (NICER) has observed seven thermonuclear X-ray bursts from the Low Mass X-ray Binary (LMXB) neutron star 4U 1728-34 from the start of…
