We study the generation of a localized peak in the primordial spectrum of curvature perturbations from a transient dissipative phase during infl

Do pulsar timing arrays observe merging primordial black holes?

Autor: Depta, Paul Frederik, Schmidt-Hoberg, Kai, Tasillo, Carlo

In this letter we evaluate whether the gravitational wave background recently observed by a number of different pulsar timing arrays could be due to merging primordial supermassive black hole binaries. We find that for homogeneously distributed primo

Primordial Black Holes (PBHs) are hypothetical black holes predicted to have been formed from density fluctuations in the early Universe. PBHs with an initial mass around $10^{14}-10^{15}$g are expected to end their evaporation at present times in a

Constant-rate inflation, including ultra-slow-roll as a special case, has been widely applied to the formation of primordial black holes with significant deviation from the standard slow-roll conditions at both the growing and decaying phases of the

Dark dimension, the swampland, and the dark matter fraction composed of primordial black holes

Autor: Anchordoqui, Luis, Antoniadis, Ignatios, Lust, Dieter

Publikováno v: Physical Review

Very recently, it was suggested that combining the Swampland program with the smallness of the dark energy and confronting these ideas to experiment lead to the prediction of the existence of a single extra-dimension (dubbed the dark dimension) with
