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…
A Dark Matter Trigger for Early Dark Energy Coincidence
Meng-Xiang Lin, Evan McDonough, J. Colin Hill +1
Early dark energy (EDE), whose cosmological role is localized in time around the epoch of matter-radiation equality in order to resolve the Hubble tension, introduces a new coincid…
The Early Dark Sector, the Hubble Tension, and the Swampland
Evan McDonough, Meng-Xiang Lin, J. Colin Hill +2
We consider the interplay of the Early Dark Energy (EDE) model, the Swampland Distance Conjecture (SDC), and cosmological parameter tensions. EDE is a proposed resolution of the Hu…
Cosmic Filament Spin from Dark Matter Vortices
Stephon Alexander, Christian Capanelli, Elisa G. M. Ferreira +1
The recent observational evidence for cosmic filament spin on megaparsec scales (Wang et al, Nature Astronomy 5, 839-845 (2021)) demands an explanation in the physics of dark matte…
Amplification of Primordial Perturbations from the Rise or Fall of the Inflaton
Keisuke Inomata, Evan McDonough, Wayne Hu
The next generation of cosmic microwave background, gravitational wave, and large scale structure, experiments will provide an unprecedented opportunity to probe the primordial pow…
Primordial Black Holes Arise When The Inflaton Falls
Keisuke Inomata, Evan McDonough, Wayne Hu
Primordial Black Holes (PBHs) have entered the forefront of theoretical cosmology, due their potential role in phenomena ranging from gravitational waves, to dark matter, to galaxy…
