An updated constraint for the Gravitational Wave Background from the Gamma-ray Pulsar Timing Array

Serena Valtolina, Colin J. Clark, Rutger van Haasteren +5

Fermi LAT observations of gamma-ray pulsars can be used to build a pulsar timing array (PTA) experiment to search for gravitational wave (GW) signals at nanohertz frequencies. At t…

FrankenStat I: a New Approach to Pulsar Timing Array Data Combination

David Wright, Kalista Wayt, Jeffrey S. Hazboun +4

In 2023, after more than two decades of searching, pulsar timing array (PTA) collaborations around the world announced evidence for a stochastic gravitational wave background. It w…

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…

Optimal robust detection statistics for pulsar timing arrays

Rutger van Haasteren, Bruce Allen, Joseph D. Romano

Pulsar timing arrays (PTAs) seek to detect a nano-Hz stochastic gravitational-wave background (GWB) by searching for the characteristic Hellings and Downs angular pattern of timing…

How to Detect an Astrophysical Nanohertz Gravitational-Wave Background

Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93

Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…
