Primordial Black Hole Formation in a Scalar Field Dominated Universe: Investigation of the Critical nature of the Collapse
Luis E. Padilla, Ethan Milligan, David J. Mulryne +1
In this paper, we investigate the critical collapse leading to primordial black hole (PBH) formation in a universe dominated by a self-interacting scalar field with a quartic poten…
Suppression of the induced gravitational wave background due to third-order perturbations
Raphael Picard, Luis E. Padilla, Karim A. Malik +1
In this work, we revisit and evaluate new source terms which contribute to the induced gravitational wave background. We study their respective contributions to the stochastic grav…
Primordial Black Hole Formation in a Scalar Field Dominated Universe
Ethan Milligan, Luis E. Padilla, David J. Mulryne +1
We present a numerical code that solves the Misner-Sharp system for a spherically symmetric cosmological model containing both a scalar field and a perfect fluid. While the code is…
