Structures of gravitational vacuum and their role in the Universe
Vladimir Burdyuzha, J. A. de Freitas Pacheco, Grigory Vereshkov
The production of gravitational vacuum defects and their contribution in energy density of the Universe are discussed. These topological microstructures could be produced as the re…
Formation and Cosmic Evolution of Elliptical Galaxies
J. A. de Freitas Pacheco, R. Michard, R. Mohayaee
A review of the present observational and theoretical status of elliptical galaxies is presented with the aim to clarify whether the monolithic or the hierarchical, is a more viabl…
Diquark degrees of freedom in the EOS and the compactness of compact stars
J. E. Horvath, G. Lugones, J. A. de Freitas Pacheco
We discuss the role of diquarks in constructing models of compact stars. These approaches are compared to recent claims of highly compact X-ray and isolated sources.
Potential Sources of Gravitational Wave Emission and Laser Beam Interferometers
J. A. de Freitas Pacheco
The properties of potential gravitational wave sources like neutron stars, black holes and binary systems are reviewed, as well as the different contributions (stochastic and conti…
Gravitation Wave Emission from Radio Pulsars Revisited
T. Regimbau, J. A. de Freitas Pacheco
We report a new pulsar population synthesis based on Monte Carlo techniques, aiming to estimate the contribution of galactic radio pulsars to the continuous gravitational wave emis…
Deformation of Rapidly Rotating Compact Stars
J. C. N. de Araujo, J. A. de Freitas Pacheco, M. Cattani +1
We have developed a numerical code to study the deformation (, where are the moments of inertia) of neutron stars in rapidly rotation…
