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…

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…
