Photon-Count Statistics of Crab X-ray Pulses: Skellam Behavior and Excess Variance in the Main Pulse
Max Worchel, Margaret M. Ferris, Sasha Levina +15
The Crab pulsar (PSR B0531+21) provides an unusually rich test bed for statistical studies of high-energy photon-counting data, owing to its extreme brightness and the contrasting…
Comparing recent PTA results on the nanohertz stochastic gravitational wave background
The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242
The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…
The NANOGrav 15-year Data Set: Evidence for a Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111
We report multiple lines of evidence for a stochastic signal that is correlated among 67 pulsars from the 15-year pulsar-timing data set collected by the North American Nanohertz O…
Long-Term Density Trend in the Mesosphere and Lower Thermosphere from Occultations of the Crab Nebula with X-Ray Astronomy Satellites
Satoru Katsuda, Teruaki Enoto, Andrea N. Lommen +9
We present long-term density trends of the Earth's upper atmosphere at altitudes between 71 and 116 km, based on atmospheric occultations of the Crab Nebula observed with X-ray ast…
A Detection of Red Noise in PSR J18242452A and Projections for PSR B1937+21 using NICER X-ray Timing Data
Jeffrey S. Hazboun, Jack Crump, Andrea N. Lommen +17
We have used X-ray data from the Neutron Star Interior Composition Explorer (NICER) to search for long time-scale, correlated variations ("red noise") in the pulse times of arrival…
A NICER View of Spectral and Profile Evolution for Three X-ray Emitting Millisecond Pulsars
Dominick M. Rowan, Zaynab Ghazi, Lauren Lugo +17
We present two years of Neutron star Interior Composition Explorer (NICER) X-ray observations of three energetic rotation-powered millisecond pulsars (MSPs): PSRs B1937+21, B1821-2…
