Comparing gravitational wave background predictions from cosmological simulations to pulsar timing observations
Stephanie Buttigieg, Debora Sijacki, Christopher J. Moore +2
The recent detection of a gravitational wave background (GWB) by pulsar timing arrays (PTAs) may represent the first evidence of gravitational waves from merging supermassive black…

Premature supermassive black hole mergers in cosmological simulations of structure formation
Stephanie Buttigieg, Debora Sijacki, Christopher J. Moore +1
The co-evolution of massive black holes (BHs) and their host galaxies is well-established within the hierarchical galaxy formation paradigm. Large-scale cosmological simulations ar…
