The three phases of self-gravitating scalar field ground states
Anthony E. Mirasola, Nathan Musoke, Mark C. Neyrinck +2
It is generally assumed that scalar field dark matter halos would contain solitonic cores -- spherically symmetric ground state configurations -- at their centers. This is especial…
UltraDark.jl: A Julia package for simulation of cosmological scalar fields
Nathan Musoke
UltraDark.jl is a Julia package for the simulation of cosmological scalar fields. Scalar fields are proposed solutions to two of the fundamental questions in cosmology: the nature…
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…
Commuter Count: Inferring Travel Patterns from Location Data
Nathan Musoke, Emily Kendall, Mateja Gosenca +4
In this Working Paper we analyse computational strategies for using aggregated spatio-temporal population data acquired from telecommunications networks to infer travel and movemen…
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…
Scalar dark matter vortex stabilization with black holes
Noah Glennon, Anthony E. Mirasola, Nathan Musoke +2
Galaxies and their dark-matter halos are commonly presupposed to spin. But it is an open question how this spin manifests in halos and soliton cores made of scalar dark matter (SDM…
Tidal disruption of solitons in self-interacting ultralight axion dark matter
Noah Glennon, Ethan O. Nadler, Nathan Musoke +3
Ultralight axions (ULAs) are promising dark matter candidates that can have a distinct impact on the formation and evolution of structure on nonlinear scales relative to the cold,…
New Horizons: Scalar and Vector Ultralight Dark Matter
D. Antypas, A. Banerjee, C. Bartram +123
The last decade has seen unprecedented effort in dark matter model building at all mass scales coupled with the design of numerous new detection strategies. Transformative advances…
Robust posterior inference when statistically emulating forward simulations
Grigor Aslanyan, Richard Easther, Nathan Musoke +1
Scientific analyses often rely on slow, but accurate forward models for observable data conditioned on known model parameters. While various emulation schemes exist to approximate…
Lighting the Dark: The Evolution of the Post-Inflationary Universe
Nathan Musoke, Shaun Hotchkiss, Richard Easther
In simple inflationary cosmological scenarios the near-exponential growth can be followed by a long period in which the Universe is dominated by the oscillating inflaton condensate…
Expectations for Inflationary Observables: Simple or Natural?
Nathan Musoke, Richard Easther
We describe the general inflationary dynamics that can arise with a single, canonically coupled field where the inflaton potential is a 4-th order polynomial. This scenario yields…
Ultraspinning limits and rotating hyperboloid membranes
Robie A. Hennigar, David Kubiznak, Robert B. Mann +1
We apply the hyperboloid membrane limit to the general Kerr-AdS metrics and their recently studied super-entropic cousins and obtain a new class of rotating black holes, for which…
On scalar curvature invariants in three dimensional spacetimes
N. K. Musoke, D. D. McNutt, A. A. Coley +1
We wish to construct a minimal set of algebraically independent scalar curvature invariants formed by the contraction of the Riemann (Ricci) tensor and its covariant derivatives up…
Scalar Polynomial Curvature Invariants in the Context of the Cartan-Karlhede Algorithm
D. Brooks, D. D. McNutt, J. P. Simard +1
We employ the Cartan-Karlhede algorithm in order to completely characterize the class of Gödel-like spacetimes for three-dimensional gravity. By examining the permitted Segre types…
Ultraspinning limits and super-entropic black holes
Robie A. Hennigar, David Kubiznak, Robert B. Mann +1
By employing the new ultraspinning limit we construct novel classes of black holes with non-compact event horizons and finite horizon area and study their thermodynamics. Our ultra…
Mathematical Properties of a Class of Four-dimensional Neutral Signature Metrics
D. Brooks, N. Musoke, D. McNutt +1
While the Lorenzian and Riemanian metrics for which all polynomial scalar curvature invariants vanish (the VSI property) are well-studied, less is known about the four-dimensional…
