Throughout the world, institutes for theoretical physics are an important tool for developing high-quality fundamental research. The International Centre for Theoretical Physics (ICTP), in collaboration with the State University of São Paulo (UNESP), created in 2011 the ICTP South American Institute for Fundamental Research located in the IFT-UNESP building in the city of São Paulo. The...
Several phenomena in the early universe can trigger a stochastic gravitational wave background (SGWB) that can be detected by current or forthcoming gravitational wave (GW) experiments. The observation of a GW signal associated to any of these sources would be a milestone in our understanding of nature. It would be the first direct measurement of the properties of the universe before th...
We plan to work on accurate and up-to-date constraints on the complete set of dimension five and six operators with scalar, fermion and vector Dark Matter (DM). We will use LHC mono-jet data, spin independent and spin dependent direct searches, relic density and CMB, and show the interplay between high and low energy data in setting bounds on the parameter space. (AU)
We intend to improve our infrastructure for seminar presentations and updated our library. (AU)

Cosmology is an exciting field that provides an enormous amount of precise data about the different properties of the cosmos. At the same time, our understanding of the Universe is based on a standard model that is troubled with deep theoretical uncertainties - the nature of dark energy and dark matter being examples of such open problems. In the standard cosmological model, called LCDM...
The dynamics of the formation of the observed large-scale structures, along with dark matter, dark energy, the accelerated expansion of the universe and their inter-relations remain as some of the biggest puzzles of modern cosmology and have been extensively investigated over the last years. In particular, understanding the nature of cosmic acceleration foresees important implications f...
This Project has the objective of applying scientific journalism on the dissemination of the scientific production by researchers from Brazilian institutions, within the Physics field, for the Brazilian Physical Society (SBF). In order to do this, the present proposal aims to perform work whose content has a simple language and that could have a broad reach among the specialized and non...
The estimation of cosmological parameters from observations allow to determine the best model that describes our universe. A crucial step in this process is the estimation of the errors associated to the measurements, codified in the covariance matrix. In this Project the student will focus on a theoretical study of the covariance matrix that takes into account the contribution of super...
Cosmology has entered an era of precision measurements. Looking to answer some of the most fundamental questions regarding the nature of our Universe, large collaborations of scientists currently carry out large and diverse astronomical experiments. A few different surveys that stand out are: Measurements of cosmic microwave background radiation anisotropy, of distant type Ia supernovae...

Physics beyond the Standard Model (SM) may lie beyond the TeV scale and be typically probed by the LHC, or may be light and very weakly coupled to the SM, forming then a ``dark sector'' possibly modifying gravity at long distance. This research project proposes directions covering both paradigms. We will explore the possibility that the dark sector be a conformal field theory (CFT) bro...
The Standard Model (SM) of the electroweak and strong interactions is a great successin describing a large amount of experimental data collected over several decades in many experiments at different energy scales. It has been tested with great precision, and calculations using quantum field theory at higher order in perturbation theory are necessary in order to reach agreement between t...
