The WDM Time-Frequency Transform in Gravitational-Wave Data Analysis I: Formalism
Aaron Johnson, Katerina Chatziioannou, Jake Summers
For slowly-varying noise, time-frequency methods offer a natural middle ground between the efficiency of the frequency domain and the generality of the more expensive time domain.…
The NANOGrav 15-year Data Set: Search for Gravitational Wave Memory
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102
We present the results of a search for nonlinear gravitational wave memory in the NANOGrav 15-year data set. We find no significant evidence for memory signals in the dataset, with…
PETRA: From the LISA global fit to a catalog of Galactic binaries
Aaron D. Johnson, Javier Roulet, Katerina Chatziioannou +3
The Laser Interferometer Space Antenna (LISA) will detect mHz gravitational waves from many astrophysical sources, including millions of compact binaries in the Galaxy, thousands o…
Rapid parameter estimation for pulsar-timing-array datasets with variational inference and normalizing flows
Michele Vallisneri, Marco Crisostomi, Aaron D. Johnson +1
In the gravitational-wave analysis of pulsar-timing-array datasets, parameter estimation is usually performed using Markov Chain Monte Carlo methods to explore posterior probabilit…
Source Confusion from Neutron Star Binaries in Ground-Based Gravitational Wave Detectors is Minimal
Aaron D. Johnson, Katerina Chatziioannou, Will M. Farr
Upgrades beyond the current second generation of ground-based gravitational wave detectors will allow them to observe tens of thousands neutron star and black hole binaries. Given…
The NANOGrav 15-year data set: Search for Transverse Polarization Modes in the Gravitational-Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +96
Recently we found compelling evidence for a gravitational wave background with Hellings and Downs (HD) correlations in our 15-year data set. These correlations describe gravitation…
