Resumo

BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making the first detection of Baryon Acoustic Oscillations (BAO) in the frequency band 980 MHz - 1260 MHz, corresponding to a redshift range 0.127 < z < 0.449. BAO is one of the most powerful probes of cosmological parameters and BINGO was designed to detect the BAO signal to a level that makes it possible to put new constraints on the equation of state of dark energy. The telescope will be built in Paraiba, Brazil and consists of two similar to 40m mirrors, a feedhorn array of 50 horns, and no moving parts, working as a drift-scan instrument. It will cover a 15 degrees declination strip centered at similar to delta = -15 degrees, mapping similar to 5400 square degrees in the sky. The BINGO consortium is Led by University of Sao Paulo with co-Leadership at National Institute for Space Research and Campina Grande Federal University (BraziL). Telescope subsystems have already been fabricated and tested, and the dish and structure fabrication are expected to start in Late 2020, as well as the road and terrain preparation. (AU)
