Cosmological consequences of classical flavor-space locked gauge field radiation

Jannis Bielefeld, Robert R. Caldwell

We propose a classical SU(2) gauge field in a flavor-space locked configuration as a species of radiation in the early universe, and show that it would have a significant imprint o…

Chiral Imprint of a Cosmic Gauge Field on Primordial Gravitational Waves

Jannis Bielefeld, Robert R. Caldwell

A cosmological gauge field with isotropic stress-energy introduces parity violation into the behavior of gravitational waves. We show that a primordial spectrum of inflationary gra…

Cosmological Leverage from the Matter Power Spectrum in the Presence of Baryon and Nonlinear Effects

Jannis Bielefeld, Dragan Huterer, Eric V. Linder

We investigate how the use of higher wavenumbers (smaller scales) in the galaxy clustering power spectrum influences cosmological constraints. We take into account uncertainties fr…

Dark Energy Scaling from Dark Matter to Acceleration

Jannis Bielefeld, Robert R. Caldwell, Eric V. Linder

The dark sector of the Universe need not be completely separable into distinct dark matter and dark energy components. We consider a model of early dark energy in which the dark en…

Freezing Out Early Dark Energy

Jannis Bielefeld, W. L. Kimmy Wu, Robert R. Caldwell +1

A phenomenological model of dark energy that tracks the baryonic and cold dark matter at early times but resembles a cosmological constant at late times is explored. In the transit…
