A search for ultra-light axions using precision cosmological data
Renée Hlozek, Daniel Grin, David J. E. Marsh +1
Ultra-light axions (ULAs) with masses in the range 10^{-33} eV <m <10^{-20} eV are motivated by string theory and might contribute to either the dark-matter or dark-energy density…
Galaxy UV-luminosity function and reionization constraints on axion dark matter
Brandon Bozek, David J. E. Marsh, Joseph Silk +1
If the dark matter (DM) were composed of axions, then structure formation in the Universe would be suppressed below the axion Jeans scale. Using an analytic model for the halo mass…
Quintessence in a quandary: prior dependence in dark energy models
David J. E. Marsh, Philip Bull, Pedro G. Ferreira +1
The archetypal theory of dark energy is quintessence: a minimally coupled scalar field with a canonical kinetic energy and potential. By studying random potentials we show that qui…
Tensor Detection Severely Constrains Axion Dark Matter
David J. E. Marsh, Daniel Grin, Renee Hlozek +1
The recent detection of B-modes by BICEP2 has non-trivial implications for axion dark matter implied by combining the tensor interpretation with isocurvature constraints from Planc…
