The NANOGrav 12.5-Year Data Set: Monitoring Interstellar Scattering Delays
Jacob E. Turner, Maura A. McLaughlin, James M. Cordes +33
We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. Dynamic spectra for the observing epochs of each pulsar were used…
Understanding and improving the timing of PSR J0737-3039B
Aristeidis Noutsos, G. Desvignes, M. Kramer +11
The double pulsar (PSR J0737-3039A/B) provides some of the most stringent tests of general relativity (GR) and its alternatives. The success of this system in tests of GR is largel…
Asymmetric mass ratios for bright double neutron-star mergers
R. D. Ferdman, P. C. C. Freire, B. B. P. Perera +11
The discovery of a radioactively powered kilonova associated with the binary neutron star merger GW170817 was the first - and still only - confirmed electromagnetic counterpart to…
Precise mass measurements for the double neutron star system J1829+2456
Henryk T. Haniewicz, Robert D. Ferdman, Paulo C. C. Freire +4
PSR J1829+2456 is a radio pulsar in a relativistic binary system with another neutron star. It has a rotational period of 41 ms and a mildly eccentric () 28-hr orbit. We…
Multi-Messenger Gravitational Wave Searches with Pulsar Timing Arrays: Application to 3C66B Using the NANOGrav 11-year Data Set
Zaven Arzoumanian, Paul T. Baker, Adam Brazier +56
When galaxies merge, the supermassive black holes in their centers may form binaries and, during the process of merger, emit low-frequency gravitational radiation in the process. I…
The NANOGrav 12.5-year Data Set: Wideband Timing of 47 Millisecond Pulsars
Md F. Alam, Zaven Arzoumanian, Paul T. Baker +67
We present a new analysis of the profile data from the 47 millisecond pulsars comprising the 12.5-year data set of the North American Nanohertz Observatory for Gravitational Waves…
