Primordial black hole formation in bulk-viscous cosmology
Zi-Yan Yuwen, Cristian Joana, Shao-Jiang Wang +1
We investigate primordial black hole (PBH) formation in a cosmological background with bulk viscosity. Using numerical simulations, we determine the collapse threshold and the resu…
Bubbles kick off primordial black holes to form more binaries
Zi-Yan Yuwen, Cristian Joana, Shao-Jiang Wang +1
Primordial black holes (PBHs) may form before cosmological first-order phase transitions, leading to inevitable collisions between PBHs and bubble walls. In this Letter, we have si…
GRChombo: An adaptable numerical relativity code for fundamental physics
Tomas Andrade, Llibert Areste Salo, Josu C. Aurrekoetxea +29
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChomb…
