Planck Constraints and Gravitational Wave Forecasts for Primordial Black Hole Dark Matter Seeded by Multifield Inflation
Wenzer Qin, Sarah R. Geller, Shyam Balaji +2
We perform a Markov Chain Monte Carlo (MCMC) analysis of a simple yet generic multifield inflation model characterized by two scalar fields coupled to each other and nonminimally c…
Primordial Black Holes from Multifield Inflation with Nonminimal Couplings
Sarah R. Geller, Wenzer Qin, Evan McDonough +1
Primordial black holes (PBHs) provide an exciting prospect for accounting for dark matter. In this paper, we consider inflationary models that incorporate realistic features from h…
Mass of a Patch of an FRW Universe
Sarah R. Geller, Jolyon K. Bloomfield, Alan H. Guth
In 1963, Zel'dovich devised a method to define the mass of a closed Friedmann-Robertson-Walker (FRW) universe, showing that by this definition it is exactly zero. Rounding out this…
