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…
The NANOGrav 15 Yr Data Set: Removing Pulsars One by One from the Pulsar Timing Array
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102
Evidence has emerged for a stochastic signal correlated among 67 pulsars within the 15-year pulsar-timing data set compiled by the NANOGrav collaboration. Similar signals have been…
Searching for stellar-origin binary black holes in LISA Data Challenge 1b: Yorsh
Diganta Bandopadhyay, Christopher J. Moore
This paper reports the first search for stellar-origin binary black holes within the LISA Data Challenges (LDC). The search algorithm and the \Yorsh{} LDC datasets, both previously…
