Braneworld effects cause primordial black holes to accrete matter far more efficiently in the early universe, producing present-day masses up to 10^5 times larger than previous estimates for the smallest allowed fundamental Planck scale.

abstract
Black holes acting as gravitational lenses produce, besides the primary and secondary weak field images, two infinite sets of relativistic images. These images can be studied using the strong field limit, an analytic method based on a logarithmic asymptotic approximation of the deflection angle. In this work, braneworld black holes are analyzed as gravitational lenses in the strong field limit and the feasibility of observation of the images is discussed.

Cosmological accretion onto braneworld black holes: a relativistic treatment
Braneworld effects cause primordial black holes to accrete matter far more efficiently in the early universe, producing present-day masses up to 10^5 times larger than previous estimates for the smallest allowed fundamental Planck scale.
