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…

The Radius of PSR J0740+6620 from NICER and XMM-Newton Data

M. C. Miller, F. K. Lamb, A. J. Dittmann +25

PSR J07406620 has a gravitational mass of , which is the highest reliably determined mass of any neutron star. As a result, a measurement of its radius wil…

A NICER View of the Massive Pulsar PSR J0740+6620 Informed by Radio Timing and XMM-Newton Spectroscopy

Thomas E. Riley, Anna L. Watts, Paul S. Ray +27

We report on Bayesian estimation of the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J07406620, conditional on pulse-profile modeling of Neutron S…

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…

Refined Mass and Geometric Measurements of the High-Mass PSR J0740+6620

Emmanuel Fonseca, H. Thankful Cromartie, Timothy T. Pennucci +42

We report results from continued timing observations of PSR J0740+6620, a high-mass, 2.8-ms radio pulsar in orbit with a likely ultra-cool white dwarf companion. Our data set consi…

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-…
