Spiral structure from the interference of gravitational eigenmodes in ultralight dark matter halos
Jacob Reinach, Hubert Bray
We use a variety of analytic and numerical techniques to approximate the geometry of individual dark matter halos when modeled as collections of ultralight scalar bosons (ULDM), fo…
Topological Big Bangs: Reflection, Itty-Bitty Blenders, and Eternal Trumpets
Hubert Bray, James Wheeler
We discuss and formalize topological means by which the initial singularity might be mollified, at the level of the spacetime manifold's structure, in classical cosmological models…
The Riemannian Penrose Inequality with Matter Density
Hubert Bray, Yiyue Zhang
Riemannian Penrose Inequalities are precise geometric statements that imply that the total mass of a zero second fundamental form slice of a spacetime is at least the mass contribu…
Spacetime Harmonic Functions and Applications to Mass
Hubert Bray, Sven Hirsch, Demetre Kazaras +2
In the pioneering work of Stern, level sets of harmonic functions have been shown to be an effective tool in the study of scalar curvature in dimension 3. Generalizations of this i…
Scalar curvature and harmonic one-forms on three-manifolds with boundary
Hubert L. Bray, Daniel L. Stern
For a homotopically energy-minimizing map on a compact, oriented -manifold with boundary, we establish an identity relating the average Euler characteristic…
Harmonic Functions and The Mass of 3-Dimensional Asymptotically Flat Riemannian Manifolds
Hubert L. Bray, Demetre P. Kazaras, Marcus A. Khuri +1
An explicit lower bound for the mass of an asymptotically flat Riemannian 3-manifold is given in terms of linear growth harmonic functions and scalar curvature. As a consequence, a…
