The NANOGrav Nine-Year Data Set: Measurement and Interpretation of Variations in Dispersion Measures
M. L. Jones, M. A. McLaughlin, M. T. Lam +21
We analyze dispersion measure (DM) variations of 37 millisecond pulsars in the 9-year NANOGrav data release and constrain the sources of these variations. Variations are significan…
The NANOGrav Nine-Year Data Set: Excess Noise in Millisecond Pulsar Arrival Times
M. T. Lam, J. M. Cordes, S. Chatterjee +22
Gravitational wave astronomy using a pulsar timing array requires high-quality millisecond pulsars, correctable interstellar propagation delays, and high-precision measurements of…
The NANOGrav Nine-Year Data Set: Noise Budget for Pulsar Arrival Times on Intraday Timescales
M. T. Lam, J. M. Cordes, S. Chatterjee +21
The use of pulsars as astrophysical clocks for gravitational wave experiments demands the highest possible timing precision. Pulse times of arrival (TOAs) are limited by stochastic…
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…
Testing Theories of Gravitation Using 21-Year Timing of Pulsar Binary J1713+0747
W. W. Zhu, I. H. Stairs, P. B. Demorest +17
We report 21-yr timing of one of the most precise pulsars: PSR J1713+0747. Its pulse times of arrival are well modeled by a comprehensive pulsar binary model including its three-di…
Long-term X-ray changes in the emission from the anomalous X-ray pulsar 4U 0142+61
M. E. Gonzalez, R. Dib, V. M. Kaspi +3
We present results obtained from X-ray observations of the anomalous X-ray pulsar (AXP) 4U 0142+61 taken between 2000-2007 using XMM-Newton, Chandra and Swift. In observations take…
Chandra and XMM-Newton Observations of the Vela-like Pulsar B1046-58
M. E. Gonzalez, V. M. Kaspi, M. J. Pivovaroff +1
We present results from Chandra and XMM-Newton observations of the radio pulsar B1046-58. A high-resolution spatial analysis reveals an asymmetric pulsar wind nebula (PWN) ~6"x11"…
