The thermonuclear X-ray bursts of 4U 1730-22
Peter Bult, Giulio C. Mancuso, Tod E. Strohmayer +11
We present observations of the historic transient 4U 1730-22 as observed with the Neutron Star Interior Composition Explorer (NICER). After remaining in quiescence since its 1972 d…
The discovery of the 528.6 Hz accreting millisecond X-ray pulsar MAXI J1816-195
Peter Bult, Diego Altamirano, Zaven Arzoumanian +15
We present the discovery of 528.6 Hz pulsations in the new X-ray transient MAXI J1816-195. Using NICER, we observed the first recorded transient outburst from the neutron star low-…
Burst-Disk Interaction in 4U 1636-536 as observed by NICER
Tolga Guver, Funda Bostanci, Tugba Boztepe +10
We present the detection of 51 thermonuclear X-ray bursts observed from 4U 1636-536 by the Neutron Star Interior Composition Explorer (NICER) over the course of a three year monito…
On the Peculiar Rotational Evolution of PSR B0950+08
Erbil Gügercinoğlu, Elif Köksal, Tolga Güver
The long-term rotational evolution of the old, isolated pulsar, PSR B0950+08 is intriguing in that its spin-down rate displays sinusoidal-like oscillations due to alternating varia…
Long term radio and X-ray evolution of the magnetar Swift J1818.0-1607
K. M. Rajwade, B. W. Stappers, A. G. Lyne +10
We report on the the long term monitoring campaign of the seemingly youngest magnetar Swift~J1818.0-1607 at radio and X-ray wavelengths over a span of one year. We obtained a coher…
Pulse Peak Migration during the Outburst Decay of the Magnetar SGR 1830-0645: Crustal Motion and Magnetospheric Untwisting
G. Younes, S. K. Lander, M. G. Baring +12
Magnetars, isolated neutron stars with magnetic field strengths typically ~G, exhibit distinctive months-long outburst epochs during which strong evolution of soft…
