Orbital motion of primordial black holes crossing Solar-type stars
Vitorio A. De Lorenci, David I. Kaiser, Patrick Peter
Primordial black holes (PBHs) are hypothetical objects that could have originated from density fluctuations in a very early phase of our Universe. Recent observations restrict the…
Observing alternatives to inflation
P. Peter
We discuss the possibility that the inflationary paradigm, undoubtfully today's best framework to understand all the present cosmological data, may still have some viable challenge…
Spectra of primordial fluctuations in two-perfect-fluid regular bounces
F. Finelli, P. Peter, N. Pinto-Neto
We introduce analytic solutions for a class of two components bouncing models, where the bounce is triggered by a negative energy density perfect fluid. The equation of state of th…
Bound states in monopoles: sources for UHECR ?
E. Huguet, P. Peter
Bound states in monopoles are studied through a simplified, Witten-like model. As the overall structure is determined in full details, it is shown in particular that only those sta…
Dynamical Stability of Witten Rings
X. Martin, P. Peter
The dynamical stability of cosmic rings, or vortons, is investigated for the particular equation of state given by the Witten bosonic model. It is found that there exists a finite…
Spontaneous Current Generation in Cosmic Strings
Patrick PETER
It is shown that in models including the standard electroweak theory and for some particular values of the underlying parameters, electric currents can be spontaneously generated i…
