Dynamical friction in self-interacting ultralight dark matter
Noah Glennon, Nathan Musoke, Ethan O. Nadler +2
We explore how dynamical friction in an ultralight dark matter (ULDM) background is affected by dark matter self-interactions. We calculate the force of dynamical friction on a poi…

Simulations of multi-field ultralight axion-like dark matter
Noah Glennon, Nathan Musoke, Chanda Prescod-Weinstein
As constraints on ultralight axion-like particles (ALPs) tighten, models with multiple species of ultralight ALP are of increasing interest. We perform simulations of two-ALP model…

Modifying PyUltraLight to model scalar dark matter with self-interactions
Noah Glennon, Chanda Prescod-Weinstein
We introduce a modification of the PyUltraLight code that models the dynamical evolution of ultralight axionlike scalar dark matter fields. Our modified code, PySiUltraLight, adds…
