Scintillation Bandwidth Measurements from 23 Pulsars from the AO327 Survey

Autor: Sheikh, Sofia Z., Brown, Grayce C., MacTaggart, Jackson, Nguyen, Thomas, Fletcher, William D., Jones, Brenda L., Koller, Emma, Petrus, Veronica, Pighini, Katie F., Rosario, Gray, Smedile, Vincent A., Stone, Adam T., You, Shawn, McLaughlin, Maura A., Turner, Jacob E., Deneva, Julia S., Lam, Michael T., Shapiro-Albert, Brent J.

A pulsar's scintillation bandwidth is inversely proportional to the scattering delay, making accurate measurements of scintillation bandwidth critical to characterize unmitigated delays in efforts to measure low-frequency gravitational waves with pul

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 found in data from the European, Indian, Parkes, and Chinese PTAs. Th

Free electrons in the interstellar medium refract and diffract radio waves along multiple paths, resulting in angular and temporal broadening of radio pulses that limits pulsar timing precision. We determine multifrequency, multi-epoch scattering tim

The detection of a stochastic gravitational wave background by pulsar timing arrays suggests the presence of a supermassive black hole binary population. Although the observed spectrum generally aligns with predictions from orbital evolution driven b
