The measurement of diffuse 21-cm radiation from the hyperfine transition neutral hydrogen (HI signal) in different redshifts is an important tool for modern cosmology. However, detecting this faint signal with non-cryogenic receivers single-dish telescopes a challenging task. BINGO (Baryon Acoustic Oscillations Integrated Neutral Gas Observations) radio telescope instrument designed to detect baryonic acoustic oscillations (BAOs) cosmological HI signal, redshift interval $0.127 \le z 0.449$....
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 first detection Baryon Acoustic Oscillations (BAO) in frequency band 980 MHz - 1260 MHz, corresponding redshift range 0.127 < z 0.449. BAO one most powerful probes parameters and was detect signal level that makes it possible put new constraints on equation state dark energy. The will be built Paraíba, Brazil...
