The NANOGrav 12.5-year Data Set: Bayesian Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries
Zaven Arzoumanian, Paul T. Baker, Laura Blecha +75
Pulsar timing array collaborations, such as the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), are seeking to detect nanohertz gravitational waves emitted…
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-…
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 11-Year Data Set: Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries
K. Aggarwal, Z. Arzoumanian, P. T. Baker +60
Observations indicate that nearly all galaxies contain supermassive black holes (SMBHs) at their centers. When galaxies merge, their component black holes form SMBH binaries (SMBHB…
The NANOGrav Nine-year Data Set: Astrometric Measurements of 37 Millisecond Pulsars
Allison M. Matthews, David J. Nice, Emmanuel Fonseca +18
Using the nine-year radio-pulsar timing data set from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), collected at Arecibo Observatory and the Green Ba…
NANOGrav Constraints on Gravitational Wave Bursts with Memory
Z. Arzoumanian, A. Brazier, S. Burke-Spolaor +39
Among efforts to detect gravitational radiation, pulsar timing arrays are uniquely poised to detect "memory" signatures, permanent perturbations in spacetime from highly energetic…
