GALACTIC COSMIC RAYS FROM PBHs AND PRIMORDIAL SPECTRA WITH A SCALE
نویسندگان
چکیده
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 a bumpy mass variance. Though essentially equivalent at the present time to the constraints from the diffuse γ-ray background, they allow a widely independent approach and they should improve sensibly in the nearby future. We discuss the resulting constraints on inflationary parameters using a Broken Scale Invariance (BSI) model as a concrete example. PACS Numbers: 04.62.+v, 98.80.Cq

Could MACHOS be Primordial Black Holes formed during the QCD Epoch?
Observations by the MACHO collaboration indicate that a signi cant fraction of the galactic halo dark matter may be in form of compact objects with masses M 0:5M . Identi cation of these objects as red or white dwarfs is problematic due to stringent observational upper limits on such dwarf populations. Primordial black hole (PBH) formation from pre-existing density uctuations is facilitated dur...
متن کامل2 Some aspects of primordial black hole physics
Small black holes should have formed in the early Universe if the density contrast was high enough. This article aims at giving a biased and partial short overview of the latest breakthroughs in this field. It first deals with tentative experimental detections thanks to gamma-rays and cosmic-rays. Primordial black holes (PBHs) are then considered as probes of the very small cosmological scales,...
متن کاملPrimordial black holes from monopoles connected by strings
Primordial black holes(PBHs) can be produced from collapsing cosmic defects such as domain walls and strings. We show how PBHs are produced in monopole-string networks considering two types of monopole-string networks.
متن کاملEffect of Primordial Black Holes on the Cosmic Microwave Background and Cosmological Parameter Estimates
We investigate the effect of nonevaporating primordial black holes (PBHs) on the ionization and thermal history of the universe. X-rays emitted by gas accretion onto PBHs modify the cosmic recombination history, producing measurable effects on the spectrum and anisotropies of the cosmicmicrowave background (CMB). Using the third-year WMAP data andCOBE FIRAS data we improve existing upper limits...
متن کاملGamma Rays from Primordial Black Holes in Supersymmetric Scenarios
Particle emission from primordial black holes (PBHs) has been studied during the past three decades, and remains an important testing ground for early-Universe and high-energy physics. This thesis gives a review of PBH formation and distribution, the Hawking emission process and its later revisions and some of the cosmological consequences associated with PBHs. The concept of supersymmetry in q...
