BINGO

BINGO (Baryon Acoustic Oscillations from Integrated Neutral Gas Observations) is a transit radio telescope currently under construction that will observe redshifted hydrogen line emission (between z = 0.13 and 0.45) by intensity mapping to measure dark energy through baryon acoustic oscillations (BAO) in the radio frequency band. The BINGO Project is an international collaboration headed by University of São Paulo, and also collaborates with researches from many countries, such as Brazil (National Institute of Space Research and Federal University of Campina Grande), China (University of Yangzhou) and England (University of Manchester and University College of London), besides support from institutions as Shanghai Jiao Tong (China), Institute for Basic Science (South Korea), IAP - Institut d’Astrophysique de Paris (France), University of Rome (Italy), IAC - Instituto de Astrofísica de Canarias (Spain), Max Planck Institute (Germany), KwaZulu-Natal University (South Africa), Universidade Federal de Itajuba (Brazil) and Universidade Federal do Cariri (Brazil). The radio telescope is financed mainly by the Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) and by the Paraíba State Government, being supervised by the researcher Elcio Abdalla, from the Institute of Physics of University of São Paulo. BINGO will consist of two mirrors: the 40-meter primary mirror reflects radiation from the sky to the secondary mirror that then directs the radiation to a focal plane of 28 horns. The signals will then be focused into a receiver and a spectrometer, after which the data will be analyzed through a data analysis pipeline on a computer.
