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 Astrophysics of Nanohertz Gravitational Waves
Sarah Burke-Spolaor, Stephen R. Taylor, Maria Charisi +12
Pulsar timing array (PTA) collaborations in North America, Australia, and Europe, have been exploiting the exquisite timing precision of millisecond pulsars over decades of observa…
Mining Gravitational-wave Catalogs To Understand Binary Stellar Evolution: A New Hierarchical Bayesian Framework
Stephen R. Taylor, Davide Gerosa
Catalogs of stellar-mass compact binary systems detected by ground-based gravitational-wave instruments (such as Advanced LIGO and Advanced Virgo) will offer insights into the demo…
Noise-marginalized optimal statistic: A robust hybrid frequentist-Bayesian statistic for the stochastic gravitational-wave background in pulsar timing arrays
Sarah J. Vigeland, Kristina Islo, Stephen R. Taylor +1
Observations have revealed that nearly all galaxies contain supermassive black holes (SMBHs) at their centers. When galaxies merge, these SMBHs form SMBH binaries (SMBHBs) that emi…
Improving timing sensitivity in the microhertz frequency regime: limits from PSR J17130747 on gravitational waves produced by super-massive black-hole binaries
B. B. P. Perera, B. W. Stappers, S. Babak +25
We search for continuous gravitational waves (CGWs) produced by individual super-massive black-hole binaries (SMBHBs) in circular orbits using high-cadence timing observations of P…
Solar System Ephemerides, Pulsar Timing, Gravitational Waves, and Navigation
T. Joseph W. Lazio, S. Bhaskaran, C. Cutler +6
In-spiraling supermassive black holes should emit gravitational waves, which would produce characteristic distortions in the time of arrival residuals from millisecond pulsars. Mul…
The NANOGrav 11-year Data Set: Pulsar-timing Constraints On The Stochastic Gravitational-wave Background
Z. Arzoumanian, P. T. Baker, A. Brazier +57
We search for an isotropic stochastic gravitational-wave background (GWB) in the newly released -year dataset from the North American Nanohertz Observatory for Gravitational Wa…
