Dust collapse in 4d einstein–gauss–bonnet gravity

D Malafarina, B Toshmatov, N Dadhich - Physics of the Dark Universe, 2020 - Elsevier
We consider gravitational collapse in the recently proposed 4D limit of Einstein–Gauss–
Bonnet gravity. We show that for collapse of a sphere made of homogeneous dust the …
