BINGO is a novel single-dish total-power telescope that will map the redshifted HI sky in a 15 degree strip, at frequencies of 960–1260 MHz (redshift z = 0.12–0.48), covering a sky area about 5000 square degrees. BINGO will have the sensitivity to accurately measure the HI power spectrum and to detect Baryon Acoustic Oscillations (BAOs) for the first time at radio wavelengths, with an r.m.s. noise of 100 µK (Battye et al. 2013). BINGO will provide complementary cosmological information to existing surveys and will measure the acoustic scale to ˜2 % precision. BINGO will serve as a pathfinder for SKA based HI Intensity Mapping experiments – by acting as a test bed for strategies to deal with problems related to calibration, component separation, parameter extraction, etc. The speaker will give an overview of BINGO, and an update on its current status.
