Our group's article, "Observing the dynamics of super-massive black hole binaries with Pulsar Timing Arrays" has been formally accepted by Physical Review Letters (PRL). This is after we received minor corrections from the referees x2. The article has been posted on the arxiv and will appear tomorrow (tonight at midnight). Finally!!
Here is the abstract: Pulsar Timing Arrays are a prime tool to study unexplored astrophysical regimes with gravitational waves. Here we show that the detection of gravitational radiation from individually resolvable super-massive black hole binary systems can yield direct information about the masses and spins of the black holes, provided that the gravitational-wave induced timing fluctuations both at the pulsar and at the Earth are detected. This in turn provides a map of the non-linear dynamics of the gravitational field and a new avenue to tackle open problems in astrophysics connected to the formation and evolution of super-massive black holes. We discuss the potential, the challenges and the limitations of these observations.
