Abstract

BINGO is a unique radio telescope designed to make the first detection of Baryon Acoustic Oscillations (BAO) at radio frequencies. This will be achieved by measuring the distribution of neutral hydrogen gas at cosmological distances using a technique called Intensity Mapping. Along with the Cosmic Microwave Background anisotropies, the scale of BAO is one of the most powerful probes of cosmological parameters, including dark energy. The telescope will be built in a low RFI site in Northern Uruguay and located in a disused, open cast, gold mine. It will operate in the frequency range going from 0.96 GHz to 1.26 GHz, be of a two-mirror compact range design with a 40 m diameter primary and have no moving parts. Such a design will give the excellent polarization performance and very low sidelobe levels required for intensity mapping. With a feedhorn array of 50 receivers, it will map a 15o declination strip as the sky drifts past the telescope. The partners in BINGO are Brazil, United Kingdom, Switzerland and Uruguay. The overall cost of the project, including personnel costs, is estimated to be 4.98 million US dollars. The current request is for 2.98 million US dollars to fund primarily the capital cost of the components for the receiver modules plus feedhorn antennas and their assembly. It is expected that assembly will take place in Brazil and that most of the components will also be supplied by Brazilian industry. An important motivation for the project is the training of Brazilian engineers and technicians in the skills required so that in the future they can produce state-of-the-art radio astronomy systems. To this end the plan is for the prototype receiver module to be constructed and tested at the world-renowned Jodrell Bank Centre for Astrophysics in Manchester by a joint Brazilian/UK team. In this way the Brazilian team will acquire the skills required to assemble and test the remainder of the 50 modules in Brazil. The experience and science goals are also advantageous for any future involvement of Brazilian scientists in the Square Kilometre Array (SKA) project. (AU)
