Probing the Distribution and Nature of Dark Matter Around Supermassive Black Holes from EMRI and IMRI Gravitational Waves
Jared Fier, Farah Abdelshahed, Lilly Kowalczyk +2
The distribution of dark matter in the immediate vicinity of supermassive black holes remains poorly understood despite its importance for galaxy evolution and precision tests of g…

Effects of the ekpyrotic mechanism on inflationary phase in loop quantum cosmologies
Christian Brown, Jared Fier, Brian Phillips +2
In bouncing cosmological models, either classical or quantum, the big bang singularity is replaced by a regular bounce. A challenging question in such models is how to keep the she…

Gravitational wave cosmology in Einstein-scalar-Gauss-Bonnet gravity
Jared Fier, Henry Han, Bowen Li +3
In the framework of Einstein-scalar-Gauss-Bonnet (EsGB) gravity, we systematically study gravitational waves (GWs), first produced by remote compact astrophysical sources and then…
