Universidade de São Paulo (USP). Instituto de Astronomia, Geofísica e Ciências Atmosféricas (IAG) (Institutional affiliation from the last research proposal) Birthplace: Brazil
Bachelor's in Physics from Federal University of Rio Grande do Norte (1976), Master's in Physics from Brazilian Center for Research Physics (1982) and Doctorate in Physics from Centro Brasileiro de Pesquisas Físicas (1990). Has experience in several branches of Physics, working on the following subjects: General Relativity and Black Hole Physics, Cosmology, Fluid Theories, Plasma Physics, Statistical Mechanics, Stochastic Dynamics, Kinetic Theory and Galactic Dynamics. He has published more than 180 articles in international journals (Factor h=45 Web of Science, h=47 INSPIRE, h=55 Google Scholar). He completed supervision of 34 Master and Graduate projects, 16 of which were Master's and 18 PhDl, of which some PhD theses were awarded (SBF 2007, CAPES 2007, SAE 2010, CAPES 2012, IAG-USP 2012). The former advisees (most of them with full supervision - scientific initiation to doctorate), are carrying out research activities, are professors at Universities and/or Research Institutes and several are CNPq productivity scholarship holders. In 1997, He proposed and coordinated the Commission for the Implementation of the Doctoral Program in Astrophysics and Cosmology at UFRN. In 2010, He proposed and coordinated the Commission for the Creation of the Professional Master's Degree in Astronomy Teaching at IAG-USP, of which he was the first Coordinator.

In this project we investigate space plasmas out of thermodynamic equilibrium based onkappa (non-Gaussian) distributions. The standard kappa distribution has been the mostexplored statistical tool to study the suprathermal component of space plasmas in solarwinds and planetary magnetospheres. The basic reason is its agreement with measurementsfrom missions like Voyager, HELIOS, WIND, Clus…
We plan to install a radio telescope 12 meters in diameter for millimeter and sub-millimeter waves, at close to 5000 m altitude, in the Argentine Andes, in collaboration with the Argentine Institute for Radio Astronomy. The main lines of research are: 1) black holes and accretion discs 2) Molecular evolution of clouds and astrobiology 3) the spiral structure of the Galaxy. Observations wi…
Current observations based on Type Ia Supernovae are indicating that the present Universe is accelerating (see Amanulah et al. 2010 and Refs. there in). Such observations are suggesting that the bulk of energy density in the Universe is repulsive and may appear like a dark energy component [in addition to the ordinary dark matter] which is probably of primordial origin.This is the interp…
The aim of our project is to utilize the observational constraints provided by the temperature anisotropy fluctuation spectrum from CMB and Big-Bang Nucleosynthesis (BBN) to probe the viability of the class of models which connect the universal Dark Matter to the universal Dark Energy. Our research is focused on models where the energy transfer between dark matter and dark energy occurs o…

Rotation Curves of Spiral Galaxies reveal the presence of an enormous quantity of a mysterious component dominating the dynamics of these objects, called Dark Matter. High resolution observations allow the construction of mass models including a well defined dark matter halo profile with a cored central density. Moreover there exists amazing relations between the structural parameters of…
The current standard cosmological model still has several conceptual problems. One of them is the fine tuning needed in both inflation models and in models describing the present state of accelerated expansion of the universe. In the new inflationary scenario, for example, is difficult to reconcile a period of rapid expansion with the subsequent reheating of the universe, as it requires f…
The present project is part of multiple efforts that are being carried out by different groups in order to understand the mysteries that are behind cosmic acceleration. The cause of this acceleration constitutes the main open problem in the cosmology field and can be the result of the existence of an unknown cosmic component (dark energy) or of the modification of gravity on large scales.…
