Impact of the observation frequency coverage on the significance of a gravitational wave background detection in PTA data
Irene Ferranti, Mikel Falxa, Alberto Sesana +8
Pulsar Timing Array (PTA) collaborations gather high-precision timing measurements of pulsars with the aim of detecting gravitational wave (GW) signals. A major challenge lies in t…
