Anti-glitches in the Ultraluminous Accreting Pulsar NGC 300 ULX-1 Observed with NICER
Paul S. Ray, Sebastien Guillot, Wynn C. G. Ho +13
We present evidence for three spin-down glitches (or `anti-glitches') in the ultraluminous accreting X-ray pulsar NGC 300 ULX-1 in timing observations made with the Neutron Star In…
NuSTAR and NICER reveal IGR J17591-2342 as a new accreting millisecond X-ray pulsar
A. Sanna, C. Ferrigno, P. S. Ray +21
We report on the discovery by the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) of the accreting millisecond X-ray pulsa…
NICER Detection of Strong Photospheric Expansion during a Thermonuclear X-Ray Burst from 4U 1820-30
L. Keek, Z. Arzoumanian, D. Chakrabarty +13
The Neutron Star Interior Composition Explorer (NICER) on the International Space Station (ISS) observed strong photospheric expansion of the neutron star in 4U 1820-30 during a Ty…
NICER Observes the Effects of an X-Ray Burst on the Accretion Environment in Aql X-1
L. Keek, Z. Arzoumanian, P. Bult +18
Accretion disks around neutron stars regularly undergo sudden strong irradiation by Type I X-ray bursts powered by unstable thermonuclear burning on the stellar surface. We investi…
NICER Discovers the Ultracompact Orbit of the Accreting Millisecond Pulsar IGR J17062-6143
Tod E. Strohmayer, Zaven Arzoumanian, Slavko Bogdanov +17
We present results of recent Neutron Star Interior Composition Explorer observations of the accreting millisecond X-ray pulsar IGR J17062-6143 that show that it resides in a circul…
NICER Discovers mHz Oscillations in the "Clocked" Burster GS 1826-238
Tod E. Strohmayer, Keith C. Gendreau, Diego Altamirano +12
We report the discovery with the Neutron Star Interior Composition Explorer (NICER) of mHz X-ray brightness oscillations from the "clocked burster." NICER observed the source in th…
