Resumo: BINGO - Baryon acoustic oscillations In Neutral Gas Observations
The BINGO experiment is a project to build a special purpose radio telescope to map redshifted neutral hydrogen emission between z = 0.13 and 0.48. It is an international project with collaborators in Brazil, Saudi Arabia, Switzerland, United Kingdom and Uruguay. It is the only radio telescope which aims at mapping neutral gas, as traced by the 21cm line, on large angular scales and at redshift z~0.3. We call this method HI intensity mapping. Using the Baryon Acoustic Oscillations (BAOs) as a standard ruler allows to measure the expansion of the universe as a function of redshift and so, to constrain the properties of dark energy. The telescope will have no moving parts and consist of a primary mirror of about 40 m diameter and a secondary a bit smaller. It will have around 50 "pixels". With this design, the accuracy on the measurement on the acoustic scale will be 2.4% for one year of integration time, by performing a drift scan survey of 10 deg x 200 deg, with a resolution!
of 40 arcmin at 1 GHz. The plan is to build the telescope in a disused open-caste gold mine in Uruguay.
