Vortices and waves in light dark matter
Lam Hui, Austin Joyce, Michael J. Landry +1
In a galactic halo like the Milky Way, bosonic dark matter particles lighter than about eV have a de Broglie wavelength larger than the average inter-particle separation and a…
Separate Universes beyond General Relativity
Wayne Hu, Austin Joyce
We establish purely geometric or metric-based criteria for the validity of the separate universe ansatz, under which the evolution of small-scale observables in a long-wavelength p…
Dark Energy vs. Modified Gravity
Austin Joyce, Lucas Lombriser, Fabian Schmidt
Understanding the reason for the observed accelerated expansion of the Universe represents one of the fundamental open questions in physics. In cosmology, a classification has emer…
Beyond the Cosmological Standard Model
Austin Joyce, Bhuvnesh Jain, Justin Khoury +1
After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical model…
Novel Probes of Gravity and Dark Energy
Bhuvnesh Jain, Austin Joyce, Rodger Thompson +29
The discovery of cosmic acceleration has stimulated theorists to consider dark energy or modifications to Einstein's General Relativity as possible explanations. The last decade ha…
