Transient Accelerated Expansion and Double Quintessence
D. Blais, D. Polarski
We consider Double Quintessence models for which the Dark Energy sector consists of two coupled scalar fields. We study in particular the possibility to have a transient accelerati…
Peculiar Relics from Primordial Black Holes in the Inflationary Paradigm
A. Barrau, D. Blais, G. Boudoul +1
Depending on various assumptions on the energy scale of inflation and assuming a primordial power spectrum of a Broken Scale Invariance (BSI) type, we explore the possibility for P…
Galactic Cosmic Rays from PBHs and Primordial Spectra with a Scale
A. Barrau, D. Blais, G. Boudoul +1
We consider the observational constraints from the detection of antiprotons in the Galaxy on the amount of Primordial Black Holes (PBH) produced from primordial power spectra with…
Accurate results for primordial black holes from spectra with a distinguished scale
David Blais, Torsten Bringmann, Claus Kiefer +1
We perform an accurate computation of the production rate for primordial black holes (PBHs). The reason is that the underlying mass variance had been overestimated systematically,…
Can Primordial Black Holes be a Significant Part of Dark Matter ?
David Blais, Claus Kiefer, David Polarski
The computation of PBH (primordial black hole) production from primordial perturbations has recently been improved by considering a more accurate relation between the primordial po…
