The Radius of the Neutron Star PSR J0614-3329 from NICER Data
M. C. Miller, A. J. Dittmann, I. M. Holt +14
Neutron star radius measurements, particularly using X-ray data collected with the Neutron star Interior Composition Explorer (NICER), have provided invaluable information for mode…
Pulse profiles of accreting neutron stars - A review of analysis methods, observations, and theoretical models
Katja Pottschmidt, Peter Kretschmar, Ekaterina Sokolova-Lapa +25
X-ray pulsars are highly magnetized ( G) neutron stars accreting from a donor star. Their characteristic X-ray emission arises from accreted material decelerated fro…
The Radius of PSR J0437-4715 from NICER Data
M. C. Miller, A. J. Dittmann, I. M. Holt +12
Neutron star Interior Composition Explorer (NICER) data have been used to estimate the masses and radii of the rotation-powered millisecond pulsars PSR J00300451, PSR J074066…
Sharp Periodic Flares and Long-Term Variability in the High-Mass X-ray Binary XTE J1829-098 from RXTE PCA, Swift BAT and MAXI Observations
Robin H. D. Corbet, Ralf Ballhausen, Peter A. Becker +20
XTE J1829-098 is a transient X-ray pulsar with a period of ~7.8 s. It is a candidate Be star system, although the evidence for this is not yet definitive. We investigated the twent…
A NICER View of PSR J12311411: A Complex Case
Tuomo Salmi, Julia S. Deneva, Paul S. Ray +16
Recent constraints on neutron star mass and radius have advanced our understanding of the equation of state (EOS) of cold dense matter. Some of them have been obtained by modeling…
A More Precise Measurement of the Radius of PSR J0740+6620 Using Updated NICER Data
Alexander J. Dittmann, M. Coleman Miller, Frederick K. Lamb +9
PSR J0740+6620 is the neutron star with the highest precisely determined mass, inferred from radio observations to be . Measurements of its radius therefo…
The giant outburst of EXO 2030+375 II: Broadband spectroscopy and evolution
R. Ballhausen, P. Thalhammer, P. Pradhan +13
In 2021, the high-mass X-ray binary EXO 2030+375 underwent a giant X-ray outburst, the first since 2006, that reached a peak flux of (3-50\,keV). The go…
The Radius of the High-mass Pulsar PSR J0740+6620 with 3.6 yr of NICER Data
Tuomo Salmi, Devarshi Choudhury, Yves Kini +14
We report an updated analysis of the radius, mass, and heated surface regions of the massive pulsar PSR J0740+6620 using Neutron Star Interior Composition Explorer (NICER) data fro…
Exploring Waveform Variations among Neutron Star Ray-tracing Codes for Complex Emission Geometries
Devarshi Choudhury, Anna L. Watts, Alexander J. Dittmann +8
Pulse Profile Modeling (PPM), the technique used to infer mass, radius and geometric parameters for rotation-powered millisecond pulsars using data from the Neutron Star Interior C…
NICER Discovery that SRGA J144459.2-604207 is an Accreting Millisecond X-ray Pulsar
Mason Ng, Paul S. Ray, Andrea Sanna +17
We present the discovery, with the Neutron Star Interior Composition Explorer (NICER), that SRGA J144459.2-604207 is a 447.9 Hz accreting millisecond X-ray pulsar (AMXP), which und…
NuSTAR observation of GRO J1744-28 at low mass accretion rate
O. König, F. Fürst, P. Kretschmar +8
We present the spectral analysis of the LMXB GRO J1744-28 using 29 ks of NuSTAR data taken in 2017 February at a low luminosity of erg/s (3-50 keV). The c…
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…
