Supermassive Black-hole Demographics & Environments With Pulsar Timing Arrays
arXiv:1903.08183
Abstract
Precision timing of large arrays (>50) of millisecond pulsars will detect the nanohertz gravitational-wave emission from supermassive binary black holes within the next ~3-7 years. We review the scientific opportunities of these detections, the requirements for success, and the synergies with electromagnetic instruments operating in the 2020s.
