How to Detect an Astrophysical Nanohertz Gravitational-Wave Background
Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93
Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…
Gravity Spy: Lessons Learned and a Path Forward
Michael Zevin, Corey B. Jackson, Zoheyr Doctor +23
The Gravity Spy project aims to uncover the origins of glitches, transient bursts of noise that hamper analysis of gravitational-wave data. By using both the work of citizen-scienc…
Measurement of the Cross-Correlation Angular Power Spectrum Between the Stochastic Gravitational Wave Background and Galaxy Over-Density
Kate Z. Yang, Jishnu Suresh, Giulia Cusin +5
We study the cross-correlation between the stochastic gravitational-wave background (SGWB) generated by binary black hole (BBH) mergers across the universe and the distribution of…
pygwb: Python-based library for gravitational-wave background searches
Arianna I. Renzini, Alba Romero-Rodrguez, Colm Talbot +31
The collection of gravitational waves (GWs) that are either too weak or too numerous to be individually resolved is commonly referred to as the gravitational-wave background (GWB).…
Searching for continuous Gravitational Waves in the second data release of the International Pulsar Timing Array
M. Falxa, S. Babak, P. T. Baker +123
The International Pulsar Timing Array 2nd data release is the combination of datasets from worldwide collaborations. In this study, we search for continuous waves: gravitational wa…
Laying the foundation of the effective-one-body waveform models SEOBNRv5: improved accuracy and efficiency for spinning non-precessing binary black holes
