Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21
We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…
Finding Supermassive Black Hole Binary Mergers in Pulsar Timing Array Data
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren
Galaxy observations suggest that mergers of supermassive black hole binaries (SMBHBs) are rare events, with rates of order one per decade across the observable Universe. We present…
Identifying Eccentricity in Binary Black Hole mergers using a Harmonic Decomposition of the Gravitational Waveform
Ben G. Patterson, Sharon Mary Tomson, Stephen Fairhurst
We show that the gravitational waveform emitted by a binary on an eccentric orbit can be naturally decomposed into a series of harmonics. The frequencies of these harmonics depend…
Reading signatures of supermassive binary black holes in pulsar timing array observations
Boris Goncharov, Shubhit Sardana, A. Sesana +10
We find the inferred properties of the putative gravitational wave background in the second data release of the European Pulsar Timing Array to be in better agreement with theoreti…
