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 very low RFI site in
South America and will operate in the frequency range from 0.96
GHz to 1.26 GHz. The telescope design consists of two \∼
40-m compact mirrors with 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 15\◦ declination strip as the sky
drifts past the field-of-view of the telescope. The BINGO
consortium is composed Universidade de Sao Paulo, Instituto
Nacional de Pesquisas Espaciais (Brazil), University of Manchester
and University College London (United Kingdom), ETH Zšurich
(Switzerland) and Universidad de La Republica (Uruguay). The
telescope assembly and horn design and fabrication are under way
in Brazil. The receiver was designed in UK and will be developed
in Brazil, with most of the components for the receiver will also
be supplied by Brazilian industry. The experience and science
goals achieved by the BINGO team will be advantageous as a
pathfinder mission for the Square Kilometre Array (SKA) project.
This paper reports the current status of the BINGO mission, as
well as preliminary results already obtained for the
instrumentation development.",
