Cosmological Perturbations from a New Approach to Inflation
Brandon Melcher, Arnab Pradhan, Scott Watson
In a previous paper we proposed a new approach to the beginning of inflation -- a lingering universe. The universe begins in a lingering state with a nearly vanishing Hubble parame…
Waiting for Inflation: A New Initial State for the Universe
Brandon Melcher, Arnab Pradhan, Scott Watson
We propose a cosmological lingering phase for the initial state prior to inflation which would help address the singularity problem of inflation. The universe begins with a constan…
The classical double copy in three spacetime dimensions
Mariana Carrillo González, Brandon Melcher, Kenneth Ratliff +2
The double copy relates scattering amplitudes in gauge and gravity theories, and has also been extended to classical solutions. In this paper, we study solutions in three spacetime…
Primordial Black Holes and Co-Decaying Dark Matter
Julian Georg, Brandon Melcher, Scott Watson
Models of Co-Decaying dark matter lead to an early matter dominated epoch -- prior to BBN -- which results in an enhancement of the growth of dark matter substructure. If these pri…
Concentrated Dark Matter: Enhanced Small-scale Structure from Co-Decaying Dark Matter
Jeff A. Dror, Eric Kuflik, Brandon Melcher +1
We study the cosmological consequences of co-decaying dark matter - a recently proposed mechanism for depleting the density of dark matter through the decay of nearly degenerate pa…
