A Joint Optimal Search for Gravitational Waves from Resolved and Unresolved Supermassive Binary Black Holes with Pulsar Timing Arrays
Boris Goncharov, Gabriela Sato-Polito, Xiaoming Bi +1
We introduce, from first principles, a joint model of the gravitational wave background (GWB) and brightest supermassive black hole binary (SMBHB) sources that may be individually…
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…
Finding Supermassive Black Hole Binary Mergers in Pulsar Timing Array Data
Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren
Galaxy observations suggest that mergers of supermassive black hole binaries (SMBHBs) are rare events, with rates of order one per decade across the observable Universe. We present…
The Targeted Standard Siren Cosmology with Pulsar Timing Arrays
Shubhit Sardana, Boris Goncharov, Jacob Cardinal Tremblay
The sky localisation of about to , which is expected to be achieved in all-sky blind searches for gravitational waves from supermassive black hole binaries (…
A Multimessenger Search for the Supermassive Black Hole Binary in 3C 66B with the Parkes Pulsar Timing Array
Jacob Cardinal Tremblay, Boris Goncharov, Rutger van Haasteren +15
A subparsec supermassive black hole binary (SMBHB) at the center of the galaxy 3C 66B is a promising candidate for continuous gravitational-wave searches with pulsar timing arrays…
Probing Ultralight Axion-like Dark Matter: A Pulsar Timing Arrays-Pulsar Polarization Arrays Synergy
Ximeng Li, Yonghao Liu, Zu-Cheng Chen +9
Ultralight axionlike dark matter (ALDM) is a leading candidate in the dark matter realm, characterized by its prominent wave properties on astronomical scales. Pulsar timing arrays…
