Gravitational Waves from the Cosmological Quark-Hadron Phase Transition Revisited
Pauline Lerambert-Potin, Jose Antonio de Freitas Pacheco
The recent claim by the NANOGrav collaboration of a possible detection of an isotropic gravitational wave background stimulated a series of investigations searching for the origin…
Astrophysical Stochastic Gravitational Wave Background
José Antonio de Freitas Pacheco
The stochastic gravitational wave background produced by supernovas, magnetars and merger of binaries constituted by a pair of compact objects is reviewed and updated. The merger o…
Primordial Regular Black Holes: Thermodynamics and Dark Matter
José Antonio de Freitas Pacheco
The possibility that dark matter particles could be constituted by extreme regular primordial black holes is discussed. Extreme black holes have zero surface temperature, and are n…
Continuous matter creation and the acceleration of the universe: a replay
Alain de Roany, J. A. de Freitas Pacheco
In a recent note (arXiv:1012.5069), the investigation performed by the present authors on the evolution of density fluctuations in an accelerated universe including matter creation…
Dark Matter Accretion into Supermassive Black Holes
Sébastien Peirani, José Antonio De Freitas Pacheco
The relativistic accretion rate of dark matter by a black hole is revisited. Under the assumption that the phase space density indicator, , remains const…
Evolution of Primordial Black Holes in a radiation and phantom energy environment
Daniel C. Guariento, J. E. Horvath, P. S. Custódio +1
In this work we extend previous work on the evolution of a Primordial Black Hole (PBH) to address the presence of a dark energy component with a super-negative equation of state as…
