Ultralight Dark Matter Constraints from NanoHertz Gravitational Waves
Shreyas Tiruvaskar, Russell Boey, Richard Easther +1
We investigate the impact of ultralight dark matter (ULDM) on the mergers of supermassive black holes (SMBH) and the resulting stochastic gravitational wave background. ULDM is bas…

Supermassive Binaries in Ultralight Dark Matter Solitons
Russell Boey, Emily Kendall, Yourong Wang +1
Ultralight (or fuzzy) dark matter (ULDM) is an alternative to cold dark matter. A key feature of ULDM is the presence of solitonic cores at the centers of collapsed halos. These wo…

Dynamical Friction and Black Holes in Ultralight Dark Matter Solitons
Russell Boey, Yourong Wang, Emily Kendall +1
We numerically simulate the motion of a black hole as it plunges radially through an ultralight dark matter soliton. We investigate the timescale in which dynamical friction reduce…
