Unbiased estimation of gravitational-wave anisotropies from noisy data

Nikolaos Kouvatsos, Alexander C. Jenkins, Arianna I. Renzini +2

One of the most exciting targets of current and future gravitational-wave observations is the angular power spectrum of the astrophysical GW background. This cumulative signal enco…

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…

Answers to frequently asked questions about the pulsar timing array Hellings and Downs curve

Joseph D. Romano, Bruce Allen

We answer frequently asked questions (FAQs) about the Hellings and Downs correlation curve -- the "smoking-gun" signature that pulsar timing arrays (PTAs) have detected gravitation…

The NANOGrav 12.5-year Data Set: Search for Gravitational Wave Memory

Gabriella Agazie, Zaven Arzoumanian, Paul T. Baker +87

We present the results of a Bayesian search for gravitational wave (GW) memory in the NANOGrav 12.5-yr data set. We find no convincing evidence for any gravitational wave memory si…

The NANOGrav 15-year Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational Wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111

The NANOGrav 15-year data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gr…

Characterizing Gravitational Wave Detector Networks: From A to Cosmic Explorer

Ish Gupta, Chaitanya Afle, K. G. Arun +44

Gravitational-wave observations by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from n…
