The impact on astrometry by solar-wind effect in pulsar timing
K. Liu, A. Parthasarathy, M. Keith +16
Astrometry of pulsars, particularly their distances, serves as a critical input for various astrophysical experiments using pulsars. Pulsar timing is a primary approach for determi…
A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing
Alexander Saffer, Emmanuel Fonseca, Scott Ransom +8
The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2\,, based on the combination of radial-velocity and model-dependent mass parameter…
Searches for signatures of ultra-light axion dark matter in polarimetry data of the European Pulsar Timing Array
N. K. Porayko, P. Usynina, J. Terol-Calvo +74
Ultra-light axion-like particles (ALPs) can be a viable solution to the dark matter problem. The scalar field associated with ALPs, coupled to the electromagnetic field, acts as an…
The NANOGrav 15 yr Data Set: Harmonic Analysis of the Pulsar Angular Correlations
Gabriella Agazie, Jeremy G. Baier, Paul T. Baker +86
Pulsar timing array observations have found evidence for an isotropic gravitational wave background with the Hellings-Downs angular correlations, expected from general relativity.…
The NANOGrav 15 Yr Data Set: Removing Pulsars One by One from the Pulsar Timing Array
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102
Evidence has emerged for a stochastic signal correlated among 67 pulsars within the 15-year pulsar-timing data set compiled by the NANOGrav collaboration. Similar signals have been…
Inference on inner galaxy structure via gravitational waves from supermassive binaries
Yifan Chen, Matthias Daniel, Daniel J. D'Orazio +107
The detection of a stochastic gravitational wave background by pulsar-timing arrays indicates the presence of a population of supermassive black hole binaries. Although the observe…
