The Non-triviality of Dynamical Chern-Simons Gravity and the Standard Model
Stephon Alexander, Heliudson Bernardo, Cyril Creque-Sarbinowski
Given the growing interest in gravitational-wave and cosmological parity-violating effects in dynamical Chern-Simons (dCS) gravity, it is crucial to investigate whether the scalar-…

Brane motion in a compact space: adiabatic perturbations of brane-bulk coupled fluids
Heliudson Bernardo, Fangyi Guo
When a brane is moving in a compact space, bulk-probing signals originating at the brane can arrive back at the brane outside the lightcone of the emitting event. In this letter, w…

Superfluid dark matter flow around cosmic strings
Heliudson Bernardo, Robert Brandenberger, Aline Favero
We consider a cosmic string moving through a gas of superfluid dark matter (SFDM) particles and analyze how it affects the dark matter distribution. We look at two different cases:…
