Radial Solutions of Multi-Field de Sitter Galileons
Alice Garoffolo, Mary Gerhardinger, Kurt Hinterbichler +1
We study static, spherically symmetric screening solutions in the -invariant multi-field de Sitter Galileon theory, with matter couplings preserving the internal…
Primordial Black Holes in a Radiation-Dominated Universe
Thomas W. Baumgarte, Katy Clough, Mary Gerhardinger +2
Primordial fluctuations frozen out during inflation re-enter the cosmological horizon and can collapse, leading to the formation of primordial black holes. We perform simulations o…
Simulating a numerical UV Completion of Quartic Galileons
Mary Gerhardinger, John T. Giblin, Andrew J. Tolley +1
The Galileon theory is a prototypical effective field theory that incorporates the Vainshtein screening mechanism--a feature that arises in some extensions of General Relativity, s…
A novel integrated Sachs-Wolfe effect from Early Dark Energy
Tristan L. Smith, John T. Giblin, Mustafa A. Amin +4
We study the nonlinear effects of minimally coupled, massless, cosmological scalar fields on the cosmic microwave background (CMB). These fields can exhibit post-recombination para…
A Well-Posed UV Completion for Simulating Scalar Galileons
Mary Gerhardinger, John T. Giblin, Andrew J. Tolley +1
The Galileon scalar field theory is a prototypical example of an effective field theory that exhibits the Vainshtein screening mechanism, which is incorporated into many extensions…
