Common-spectrum process versus cross-correlation for gravitational-wave searches using pulsar timing arrays

no code implementations7 Dec 2020 Joseph D. Romano, Jeffrey S. Hazboun, Xavier Siemens, Anne M. Archibald

Here we give a frequentist analysis of a very simple signal+noise model showing that the current lack of evidence for spatial correlations is consistent with the magnitude of the correlation coefficients for pairs of Earth-pulsar baselines in the array, and the fact that pulsar timing arraysbare most-likely operating in the intermediate-signal regime.

Realistic sensitivity curves for pulsar timing arrays

1 code implementation9 Jul 2019 Jeffrey S. Hazboun, Joseph D. Romano, Tristan L. Smith

We construct realistic sensitivity curves for pulsar timing array searches for gravitational waves, incorporating both red and white noise contributions to individual pulsar noise spectra, as well as the effect of fitting to a pulsar timing model.

An Acoustical Analogue of a Galactic-scale Gravitational-Wave Detector

no code implementations14 Mar 2018 Michael T. Lam, Joseph D. Romano, Joey S. Key, Marc Normandin, Jeffrey S. Hazboun

By precisely monitoring the "ticks" of Nature's most precise clocks (millisecond pulsars), scientists are trying to detect the "ripples in spacetime" (gravitational waves) produced by the inspirals of supermassive black holes in the centers of distant merging galaxies.

Sensitivity curves for searches for gravitational-wave backgrounds

2 code implementations20 Oct 2013 Eric Thrane, Joseph D. Romano

We propose a graphical representation of detector sensitivity curves for stochastic gravitational-wave backgrounds that takes into account the increase in sensitivity that comes from integrating over frequency in addition to integrating over time.
