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…

The NANOGrav 15 yr Data Set: Piecewise Power-Law Reconstruction of the Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +108
The NANOGrav 15-year (NG15) data set provides evidence for a gravitational-wave background (GWB) signal at nanohertz frequencies, which is expected to originate either from a cosmi…

Future Space-based Gamma-ray Pulsar Timing Arrays
Matthew Kerr, Zorawar Wadiasingh, Adrien Laviron +3
Radio pulsar timing array (PTA) experiments using millisecond pulsars (MSPs) are beginning to detect nHz gravitational waves (GWs). MSPs are bright GeV gamma-ray emitters, and all-…
