Bayesian Solar Wind Modeling with Pulsar Timing Arrays
Jeffrey S. Hazboun, Joseph Simon, Dustin R. Madison +27
Using Bayesian analyses we study the solar electron density with the NANOGrav 11-year pulsar timing array (PTA) dataset. Our model of the solar wind is incorporated into a global f…
The NANOGrav 12.5-year data set: Search for Non-Einsteinian Polarization Modes in theGravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +68
We search NANOGrav's 12.5-year data set for evidence of a gravitational wave background (GWB) with all the spatial correlations allowed by general metric theories of gravity. We fi…
Searching For Gravitational Waves From Cosmological Phase Transitions With The NANOGrav 12.5-year dataset
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +62
We search for a first-order phase transition gravitational wave signal in 45 pulsars from the NANOGrav 12.5 year dataset. We find that the data can be modeled in terms of a strong…
The NANOGrav 12.5-Year Data Set: Polarimetry and Faraday Rotation Measures from Observations of Millisecond Pulsars with the Green Bank Telescope
Haley M. Wahl, Maura McLaughlin, Peter A. Gentile +28
In this work, we present polarization profiles for 23 millisecond pulsars observed at 820 MHz and 1500 MHz with the Green Bank Telescope as part of the NANOGrav pulsar timing array…
The NANOGrav 11yr Data Set: Limits on Supermassive Black Hole Binaries in Galaxies within 500Mpc
Zaven Arzoumanian, Paul T. Baker, Adam Brazier +54
Supermassive black hole binaries (SMBHBs) should form frequently in galactic nuclei as a result of galaxy mergers. At sub-parsec separations, binaries become strong sources of low-…
PINT: A Modern Software Package for Pulsar Timing
Jing Luo, Scott Ransom, Paul Demorest +13
Over the past few decades, the measurement precision of some pulsar-timing experiments has advanced from ~10 us to ~10 ns, revealing many subtle phenomena. Such high precision dema…
