BINGO-ABDUS: A radiotelescope to unveil the dark sector of the Universe

The Baryon Acoustic Oscillations from Integrated Neutral Gas Observations (BINGO) telescope is an international collaboration, led by Brazil and China, aiming to explore the Universe’s history through integrated post-reionization 21 cm signals and fast radio emissions. It is concentrated on the important period for understanding the recent Universe dynamics that have shed light on the existence of the Dark Sector. In its first phase, BINGO will explore the southern celestial Hemisphere to observe neutral hydrogen signals from when the Universe was between 8.969 and 12.112 billion years old (These age values are from the cosmology provided by PLANCK satellite assuming a flat - ΛCDM with H₀ = 67.36 km/s/Mpc, Ω_m = 0.3153, and Ω_Λ = 0.6847.) in an angular resolution of 40 arcmins, and for the next phases reaching far epochs when the Universe was 3.116 billion years old up to 27 arcmin resolution which is poor for identifying individual sources, however important for mapping out the Universe in large scales using the Intensity Mapping observational method. For identifying individually fast radio sources, the Advanced Bingo Dark Universe Studies (ABDUS) project has been proposed and developed and will combine the current BINGO construction with the main single-dish telescope and stations of phased-array and outrigger, which will reach out up to 2.5 arcsec resolution to pinpoint individual radio sources as Fast Radio Bursts by interferometry.
