Anisotropies in the PTA gravitational wave background: what can they teach us about supermassive black hole binaries?
Matias Zaldarriaga, Gabriela Sato-Polito
The gravitational wave background detected by pulsar timing arrays is sourced by a finite population of supermassive black hole binaries, and is therefore anisotropic. We ask what…
Summary statistic for pulsar timing arrays
Gabriela Sato-Polito, Matias Zaldarriaga, Barak Zackay
The timing residuals produced by gravitational-wave signals can be described as an incoherent (pulsar term) contribution and a coherent (Earth term) map on the sky, which PTAs meas…
A Joint Optimal Search for Gravitational Waves from Resolved and Unresolved Supermassive Binary Black Holes with Pulsar Timing Arrays
Boris Goncharov, Gabriela Sato-Polito, Xiaoming Bi +1
We introduce, from first principles, a joint model of the gravitational wave background (GWB) and brightest supermassive black hole binary (SMBHB) sources that may be individually…
Uncertainties in the supermassive black hole abundance and implications for the GW background
Gabriela Sato-Polito, Matias Zaldarriaga
The present-day mass function of supermassive black holes is the most important observable quantity for the prediction and theoretical interpretation of the gravitational wave back…
Evolution of SMBHs in light of PTA measurements: implications for growth by mergers and accretion
Gabriela Sato-Polito, Matias Zaldarriaga, Eliot Quataert
We study the growth of supermassive black holes accounting for both accretion and mergers. The former is informed by observations of the quasar luminosity function (QLF) and the la…
The distribution of the gravitational-wave background from supermassive black holes
Gabriela Sato-Polito, Matias Zaldarriaga
The recent detection of gravitational waves (GWs) by pulsar timing array (PTA) collaborations spurred a variety of questions regarding the origin of the signal and the properties o…
