Residual Galactic binary foreground in LISA stochastic gravitational-wave background inference: source power concentration and spectral degeneracy
Ruo-Yu Guan, Yan Wang
Galactic compact binaries are expected to form a dominant foreground in the millihertz band of the Laser Interferometer Space Antenna (LISA). Residual power from injected sources t…
Red noise and evolving signals: a complete frequentist approach to supermassive black hole binary searches with pulsar timing array
Xuan Tao, Boris Goncharov, Yiqian Qian +2
Searches for gravitational waves (GWs) from isolated supermassive black hole binaries (SMBHBs) in pulsar timing array (PTA) data require simultaneous estimation of signal and noise…
Scalable continuous gravitational wave detection in PTA data with non-parametric red noise suppression and optimal pulsar selection
Yi-Qian Qian, Yan Wang, Soumya D. Mohanty +1
Bayesian methods for the detection of continuous gravitational waves (CGWs) in Pulsar Timing Array (PTA) data incur substantial computational costs that grow rapidly due to the num…
Constructing a gravitational wave analysis pipeline for extremely large mass ratio inspirals
Tian-Xiao Wang, Yan Wang, Alejandro Torres-Orjuela +4
Extremely large mass-ratio inspirals (XMRIs), consisting of a brown dwarf orbiting a supermassive black hole, emit long-lived and nearly monochromatic gravitational waves in the mi…
Detection and parameter estimation of supermassive black hole ringdown signals using a pulsar timing array
Xuan Tao, Yan Wang, Soumya D. Mohanty
Gravitational wave (GW) searches using pulsar timing arrays (PTAs) are commonly assumed to be limited to a GW frequency of Hz given by the Nyquist rate as…
Hierarchical search method for gravitational waves from stellar-mass binary black holes in noisy space-based detector data
Yao Fu, Yan Wang, Soumya D. Mohanty
Future space-based laser interferometric detectors, such as LISA, will be able to detect gravitational waves (GWs) generated during the inspiral phase of stellar-mass binary black…
