The Astrophysics of Nanohertz Gravitational Waves
Sarah Burke-Spolaor, Stephen R. Taylor, Maria Charisi +12
Pulsar timing array (PTA) collaborations in North America, Australia, and Europe, have been exploiting the exquisite timing precision of millisecond pulsars over decades of observa…
Microarcsecond VLBI pulsar astrometry with PSR II. parallax distances for 57 pulsars
A. T. Deller, W. M. Goss, W. F. Brisken +8
We present the results of PSR, a large astrometric project targeting radio pulsars using the Very Long Baseline Array (VLBA). From our astrometric database of 60 pulsars, we hav…
The NANOGrav Nine-year Data Set: Limits on the Isotropic Stochastic Gravitational Wave Background
Zaven Arzoumanian, Adam Brazier, Sarah Burke-Spolaor +45
We compute upper limits on the nanohertz-frequency isotropic stochastic gravitational wave background (GWB) using the 9-year data release from the North American Nanohertz Observat…
Limits on the Stochastic Gravitational Wave Background from the North American Nanohertz Observatory for Gravitational Waves
P. B. Demorest, R. D. Ferdman, M. E. Gonzalez +24
We present an analysis of high-precision pulsar timing data taken as part of the North American Nanohertz Observatory for Gravitational waves (NANOGrav) project. We have observed 1…
The Gaussian Plasma Lens in Astrophysics. Refraction
Andrew W. Clegg, Alan L. Fey, T. Joseph W. Lazio
We consider the geometrical optics for refraction of a distant radio source by an interstellar plasma lens, with application to a lens with a Gaussian electron column density profi…
