The Loud Tail of the Supermassive Black Hole Binary Population: Multimessenger Candidates and Prospects for SKAO
Juhan Raidal, Ville Vaskonen, Juan Urrutia +1
We assess whether electromagnetically identified supermassive black hole (SMBH) binary candidates populate the rare, high-amplitude tail of the gravitational wave (GW) amplitude di…
The Heavy Tailed Non-Gaussianity of the Supermassive Black Hole Gravitational Wave Background
Juhan Raidal, Juan Urrutia, Ville Vaskonen +1
We study the non-Gaussian features of the gravitational wave (GW) background generated by a population of inspiraling supermassive black hole (SMBH) binaries. We show that the SMBH…
CMB anisotropies from cosmic (super)strings in light of ACT DR6
Juhan Raidal, Anastasios Avgoustidis, Edmund Copeland +1
We present updated constraints on cosmic string and superstring parameters derived from Cosmic Microwave Background (CMB) anisotropies. The constraints are obtained via Markov Chai…
The stochastic gravitational wave background from cosmic superstrings
Anastasios Avgoustidis, Edmund J. Copeland, Adam Moss +1
We study the stochastic gravitational wave background sourced by a network of cosmic superstrings and demonstrate that incorporating higher-mass string species, beyond the fundamen…
Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Statistics of the supermassive black hole gravitational wave background anisotropy
Juhan Raidal, Juan Urrutia, Ville Vaskonen +1
We study the statistical properties of the anisotropy in the gravitational wave (GW) background originating from supermassive black hole (SMBH) binaries. We derive the distribution…
Eccentricity effects on the supermassive black hole gravitational wave background
Juhan Raidal, Juan Urrutia, Ville Vaskonen +1
We studied how eccentricity affects the gravitational wave (GW) spectrum from supermassive black hole (SMBH) binaries. We developed a fast and accurate semi-analytic method for com…
Gravitational Waves from SMBH Binaries in Light of the NANOGrav 15-Year Data
John Ellis, Malcolm Fairbairn, Gert Hütsi +4
The NANOGrav Collaboration has recently announced evidence for nHz gravitational waves (GWs), in the form of a Hellings-Downs angular correlation in the common-spectrum process tha…
