Carr criterion and mass gaps in non-singular primordial black hole formation
Jens Boos, Arif KaÄan GündoÄdu, Marek Hartenfels
Non-singular gravitational theories are expected to be relevant in the early universe. In this paper, we derive a set of effective Friedmann equations describing the dynamics of ma…

Microlensing of non-singular black holes at finite size: a ray tracing approach
Jens Boos, Hao Hu
We study the gravitational microlensing of various static and spherically symmetric non-singular black holes (and horizonless, non-singular compact objects of similar size). For po…

New models of nonsingular black hole dark matter from limiting curvature
Selin AÅmanoÄlu, Jens Boos, Christopher D. Carone
We consider phenomenological models for nonsingular black holes that satisfy the limiting curvature condition (i.e., that have curvatures that are always sub-Planckian in size) whi…
