Direction-of-arrival estimation of a gravitational wave by correlations between quadrupole moments of pulsar timings
Taichi Ueyama, Hodaka Tamura, Hideki Asada
Can we estimate the direction of arrival (DOA) of a gravitational wave (GW) signal from pulsar timing array observations? The present paper addresses the inverse problem, for which…

Can we hear beats with pulsar timing arrays?
Shun Yamamoto, Hideki Asada
An isolated supermassive black hole binary (SMBHB) produces an identical cross-correlation pattern of pulsar timings as an isotropic stochastic background gravitational waves (GWs)…

Hemisphere-averaged Hellings-Downs curve between pulsar pairs for a gravitational wave source
Tatsuya Sasaki, Kohei Yamauchi, Shun Yamamoto +1
The Hellings-Downs (HD) curve plays a crucial role in search for nano-hertz gravitational waves (GWs) with pulsar timing arrays. We discuss the angular pattern of correlations for…
