Higher Harmonics of Double White Dwarfs in the Centihertz Band: Linking LISA and DECIGO
Naoki Seto
We investigate the detectability of post-Newtonian higher harmonics from Galactic double white dwarfs in the centihertz band ( Hz). Using a synthetic population, we show…
Tracking the Long-Term GW Phase Evolution for HM Cancri-like Binaries with LISA
Naoki Seto
From prolonged X-ray and optical data of the ultra-compact binary HM Cancri, two groups recently measured the second derivative of its orbital frequency. The space gravitational wa…
On networks of space-based gravitational-wave detectors
Rong-Gen Cai, Zong-Kuan Guo, Bin Hu +7
The space-based laser interferometers, LISA, Taiji and TianQin, are targeting to observe milliHz gravitational waves (GWs) in the 2030s. The joint observations from multiple space-…
Astrophysics with the Laser Interferometer Space Antenna
Pau Amaro Seoane, Jeff Andrews, Manuel Arca Sedda +156
The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many…
Correlation of Gravitational Wave Background Noises and Statistical Loss for Angular Averaged Sensitivity Curves
Naoki Seto
Gravitational wave backgrounds generate correlated noises to separated detectors. This correlation can induce statistical losses to actual detector networks, compared with idealize…
