The essence of the memory burden effect is that a load of information carried by a system
stabilizes it. This universal effect is especially prominent in systems with a high capacity of …

It has been recently proposed that Hawking evaporation might slow down after a black hole
has lost about half of its mass. Such an effect, called" memory burden", is parameterized as …

In the last two years, the dark dimension scenario has emerged as focal point of many
research interests. In particular, it functions as a stepping stone to address the cosmological …

We discuss some of the the open questions and the roadmap in the physics of primordial
black holes. Black holes are the only dark matter candidate that is known to actually exit …

Our Universe is permeated with interstellar plasma, which prevents propagation of low-
frequency electromagnetic waves. Here, we show that two dramatic consequences arise out …

Primordial black holes (PBHs) hidden in the incredible bulk of the dark dimension could
escape constraints from non-observation of their Hawking radiation. Since these five …

In a recent publication we studied the decay rate of primordial black holes perceiving the
dark dimension, an innovative five-dimensional (5D) scenario that has a compact space with …

We describe a realistic mechanism whereby black holes with significant QCD color charge
could have formed during the early Universe. Primordial black holes (PBHs) could make up …

Microscopic horizonless relics could form in the early universe either directly through
gravitational collapse or as stable remnants of the Hawking evaporation of primordial black …

Due to the inevitable existence of quantum effects, a classical description generically breaks
down after a finite quantum break‐time tq t_q. We aim to find criteria for determining tq t_q …
