Data span and frequency coverage requirements for robust detection and inference in PTAs: A case study with EPTA DR2
Irene Ferranti, Mikel Falxa, Federico Fantoccoli +2
Pulsar Timing Arrays (PTAs) are approaching the sensitivity required for a detection of the nanohertz stochastic gravitational-wave background (GWB). This makes it crucial to…
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…
Separating deterministic and stochastic gravitational wave signals in realistic pulsar timing array datasets
Irene Ferranti, Golam Shaifullah, Aurelien Chalumeau +1
Recent observations by pulsar timing arrays indicate the presence of gravitational wave signals, likely from supermassive black hole binaries. These binaries can produce two types…
The second data release from the European Pulsar Timing Array V. Search for continuous gravitational wave signals
J. Antoniadis, P. Arumugam, S. Arumugam +97
We present the results of a search for continuous gravitational wave signals (CGWs) in the second data release (DR2) of the European Pulsar Timing Array (EPTA) collaboration. The m…
