Abstract

This project aims at assuring the permanence of the proponents in the world leadership in astroparticle physics through the participation in the Cherenkov Telescope Array Observatory (CTA). CTA is an international collaboration which intends to construct the new generation of ground gamma ray telescopes to study astroparticle physics among other subjects of astrophysical interest. The plan is to build hundreds of telescopes in three different configurations in order to detect gamma rays with energies between 20 GeV and 300 TeV. Ground based gamma ray telescopes have been proved to produce outstanding results over the last two decades. The CTA Observatory will start to be built in 2016 and by completion (2019) it will have 10 times more sensitivity than any currently operating gamma ray telescope. In the past five years, the scientists involved in this project have developed astrophysical models, proposal for data analysis, simulations and instrumentation related to the physics and astrophysics of CTA. This effort was supported by FAPESP via two regular grants (process 2010/19514-6 and 2012/22540-4) and many scholarships. The success of the work done in the past years has culminated in this proposal in which we request support from FAPESP to improve our studies in: a) new physics: dark matter and Lorentz Invariance, b) cosmic rays and gamma rays: production and propagation, c) air showers and the configuration of telescopes, d) instrumentation of telescopes and e) astroparticle physics outreach. We request here financial support to continue the development of the medium size telescopes of CTA in partnership with Brazilian industries. Our participation in the instrumentation of the telescopes is fundamental in order to guarantee the access to the most important data set in astroparticle physics to be recorded by the CTA Observatory in the next two decades which will allow us to do the science listed above.
