The NANOGrav 12.5-Year Data Set: Monitoring Interstellar Scattering Delays
Jacob E. Turner, Maura A. McLaughlin, James M. Cordes +33
We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. Dynamic spectra for the observing epochs of each pulsar were used…
Your: Your Unified Reader
Kshitij Aggarwal, Devansh Agarwal, Joseph W Kania +9
The advancement in signal processing and GPU based systems has enabled new transient detectors at various telescopes to perform much more sensitive searches than their predecessors…
Understanding and improving the timing of PSR J0737-3039B
Aristeidis Noutsos, G. Desvignes, M. Kramer +11
The double pulsar (PSR J0737-3039A/B) provides some of the most stringent tests of general relativity (GR) and its alternatives. The success of this system in tests of GR is largel…
On the detectability of ultra-compact binary pulsar systems
Nihan Pol, Maura McLaughlin, Duncan R. Lorimer +1
Using neural networks, we integrate the ability to account for Doppler smearing due to a pulsar's orbital motion with the pulsar population synthesis package \psrpoppy\ to develop…
A Study in Frequency-Dependent Effects on Precision Pulsar Timing Parameters with the Pulsar Signal Simulator
Brent J. Shapiro-Albert, Jeffrey S. Hazboun, Maura A. McLaughlin +1
In this paper we introduce a new Python package, the Pulsar Signal Simulator, or PsrSigSim, which is designed to simulate a pulsar signal from emission at the pulsar, through the i…
The NANOGrav 12.5-year Data Set: Search For An Isotropic Stochastic Gravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +58
We search for an isotropic stochastic gravitational-wave background (GWB) in the -year pulsar timing data set collected by the North American Nanohertz Observatory for Gravit…
