We review here a new scenario of hot spot electroweak baryogenesis where the local energy released in the gravitational collapse to form primordial black holes (PBHs) at the quark-hadron (QCD) epoch drives over-the-barrier sphaleron transitions in a far from equilibrium environment with just the standard model CP violation. Baryons are efficiently produced in relativistic collisions around the black holes and soon redistribute to the rest of the universe, generating the observed matter…

The recent interpretation of cold dark matter as the sum of contributions of different mass Primordial Black Hole (PBH) families [1] could explain a number of so far unsolved astrophysical mysteries.
The origins of massive black holes
Massive black holes (MBHs) inhabit galaxy centers, power luminous quasars and Active Galactic Nuclei (AGN) and shape their cosmic environment with the energy they produce. The origins of MBHs remain
The Clustering Dynamics of Primordial Black Boles in N-Body Simulations
We explore the possibility that Dark Matter (DM) may be explained by a nonuniform background of approximately stellar mass clusters of Primordial Black Holes (PBHs) by simulating the evolution from
Detecting Bypassing Micro Black Holes
Contemporarily, convincing evidence is lacking for the existence of micro black holes due to their small masses. In this paper, a specific situation is discussed in which a Schwarzschild micro black
CADERNOS DE ASTRONOMIA Uma publicação do Núcleo Cosmo-ufes & PPGCosmo-UFES
The investigation of black holes – astronomical objects whose density tends to infinity and which are capable of producing marked deformation in space-time – has experienced a great impulse in recent
New horizons for fundamental physics with LISA
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitational interaction is
Exploring the High-redshift PBH-ΛCDM Universe: Early Black Hole Seeding, the First Stars and Cosmic Radiation Backgrounds
We explore the observational implications of a model in which primordial black holes (PBHs) with a broad birth mass function ranging in mass from a fraction of a solar mass to ∼106 M ⊙, consistent
Exploring the early Universe with Gaia and Theia
It has recently been pointed out that Gaia is capable of detecting a stochastic gravitational wave background in the sensitivity band between the frequency of pulsar timing arrays and LISA. We argue
Long-range enhanced mutual information from inflation
The quantum origin of cosmological primordial perturbations is a cornerstone framework in the interplay between gravity and quantum physics. In this paper we study the mutual information between two
Baryogenesis through asymmetric Hawking radiation from primordial black holes as dark matter
We examine the extent to which primordial black holes (PBHs) can constitute the observed dark matter while also giving rise to the measured matter-antimatter asymmetry and account for the observed


Primordial black holes, dark matter and hot-spot electroweak baryogenesis at the quark-hadron epoch
We propose a scenario in which the quantum fluctuations of a light stochastic spectator field during inflation, for instance the QCD axion, generate large curvature fluctuations in the radiation era.
A common origin for baryons and dark matter
The origin of the baryon asymmetry of the Universe (BAU) and the nature of dark matter are two of the most challenging problems in cosmology. We propose a scenario in which the gravitational collapse
Cosmic microwave background limits on accreting primordial black holes
Interest in the idea that primordial black holes (PBHs) might comprise some or all of the dark matter has recently been rekindled following LIGO’s first direct detection of a binary-black-hole
Massive Primordial Black Holes as Dark Matter and their detection with Gravitational Waves
Massive Primordial Black Holes (MPBH) can be formed after inflation due to broad peaks in the primordial curvature power spectrum that collapse gravitationally during the radiation era, to form
Primordial Black Hole Formation during the QCD Epoch
We consider the formation of horizon-size primordial black holes (PBH{close_quote}s) from pre-existing density fluctuations during cosmic phase transitions. It is pointed out that the formation of
Primordial black holes with an accurate QCD equation of state
Making use of definitive new lattice computations of the Standard Model thermodynamics during the quantum chromodynamic (QCD) phase transition, we calculate the enhancement in the mass distribution
Primordial Black Holes from the QCD Axion.
A mechanism to generate primordial black holes (PBHs) that is independent of cosmological inflation and occurs slightly below the QCD phase transition and is naturally realized in QCD axion models with domain wall number N_{DW}>1 and Peccei-Quinn symmetry broken after inflation.
