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…
Timing Gamma-ray Pulsars using Gibbs Sampling
Colin J. Clark, Serena Valtolina, Lars Nieder +1
Timing analyses of gamma-ray pulsars in the Fermi Large Area Telescope data set can provide sensitive probes of many astrophysical processes, including timing noise in young pulsar…
Dissecting the nanohertz gravitational wave sky: Frequency-correlated anisotropy induced by eccentric supermassive black hole binaries
Beatrice Eleonora Moreschi, Serena Valtolina, Alberto Sesana +5
Revealing the nature of the nanohertz gravitational wave (GW) signal recently reported by pulsar timing array (PTA) collaborations around the world is the next goal of low-frequenc…
Regularizing the Pulsar Timing Array likelihood: A path towards Fourier Space
Serena Valtolina, Rutger van Haasteren
The recent announcement of evidence for a stochastic background of gravitational waves (GWB) in pulsar timing array (PTA) data has piqued interest across the scientific community.…
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…
Source anisotropies and pulsar timing arrays
Bruce Allen, Deepali Agarwal, Joseph D. Romano +1
Pulsar timing arrays (PTA) hunt for gravitational waves (GW) by searching for the correlations that GWs induce in the time-of-arrival residuals from different pulsars. If the GW so…
Pulsar timing array source ensembles
Bruce Allen, Serena Valtolina
The stochastic gravitational wave background for pulsar timing arrays is often modeled by a Gaussian ensemble which is isotropic and unpolarized. However, the Universe has a discre…
Testing strengths, limitations and biases of current Pulsar Timing Arrays detection analyses on realistic data
Serena Valtolina, Golam Shaifullah, Anuradha Samajdar +1
State-of-the-art searches for gravitational waves (GWs) in pulsar timing array (PTA) datasets model the signal as an isotropic, Gaussian and stationary process described by a power…
