报告题目:BINGO: HI Intensity Mapping Using a Novel Single-Dish Radio Telescope

摘 要Baryon Acoustic Oscillations BAOs from Integrated Neutral Gas Observation (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 (corresponding to redshifts 0.12 to 0.48), covering a sky area about 5000 square degrees. Using a focal plane array of 50 horns, 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. This will provide complementary cosmological information to existing surveys and will measure the acoustic scale to 2 % precision. The final, ultra-deep HI map will provide a wealth of cosmological and astrophysical information. To achieve this, the BINGO telescope has been designed specifically to minimise systematics. The BINGO project is funded and the construction of Phase I is currently under preparation in Uruguay.
