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…
What is the origin of the JWST SMBHs?
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
We present a new semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) that is based on the extended Press-Schechter formalism and phenomenologic…
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…
In Search of the Biggest Bangs since the Big Bang
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
Many galaxies contain supermassive black holes (SMBHs), whose formation and history raise many puzzles. Pulsar timing arrays have recently discovered a low-frequency cosmological "…
Consistency of JWST Black Hole Observations with NANOGrav Gravitational Wave Measurements
John Ellis, Malcolm Fairbairn, Gert Hütsi +3
JWST observations have opened a new chapter in studies of supermassive black holes (SMBHs), stimulating discussion of two puzzles: the abundance of SMBHs in the early Universe and…
The dark timbre of gravitational waves
Juan Urrutia, Ville Vaskonen
Gravitational wave timbre, the relative amplitude and phase of the different frequency harmonics, can change due to interactions with low-mass halos. We focus on binaries in the LI…
