A NICER View on the 2020 Magnetar-Like Outburst of PSR J1846-0258
Chin-Ping Hu, Lucien Kuiper, Alice K. Harding +6
We report on our monitoring of the strong-field magnetar-like pulsar PSR J1846-0258 with the Neutron Star Interior Composition Explorer (NICER) and the timing and spectral evolutio…
A new small glitch in Vela discovered with a hidden Markov model
L. Dunn, A. Melatos, C. M. Espinoza +2
A striking feature of the Vela pulsar (PSR J08354510) is that it undergoes sudden increases in its spin frequency, known as glitches, with a fractional amplitude on the order of…
Timing six energetic rotation-powered X-ray pulsars, including the fast-spinning young PSR J0058-7218 and Big Glitcher PSR J0537-6910
Wynn C. G. Ho, Lucien Kuiper, Cristobal M. Espinoza +14
Measuring a pulsar's rotational evolution is crucial to understanding the nature of the pulsar. Here we provide updated timing models for the rotational evolution of six pulsars, f…
VLA proper motion constraints on the origin, age, and potential magnetar future of PSR J17343333
C. M. Espinoza, M. Vidal-Navarro, W. C. G. Ho +2
The characteristic age of PSR J17343333 estimated from its current spin down rate implies that it is a young pulsar ( kyr). But the time derivative of its spin down rate…
Proper motion, spectra, and timing of PSR J1813-1749 using Chandra and NICER
Wynn C. G. Ho, Sebastien Guillot, P. M. Saz Parkinson +7
PSR J1813-1749 is one of the most energetic rotation-powered pulsars known, producing a pulsar wind nebula (PWN) and gamma-ray and TeV emission, but whose spin period is only measu…
Return of the Big Glitcher: NICER timing and glitches of PSR J0537-6910
Wynn C. G. Ho, Cristobal M. Espinoza, Zaven Arzoumanian +7
PSR J0537-6910, also known as the Big Glitcher, is the most prolific glitching pulsar known, and its spin-induced pulsations are only detectable in X-ray. We present results from a…
