Abstract

BINGO is a unique radio telescope designed to make the first detection of Baryon Acoustic Oscillations (BAO) at radio frequencies by measuring the distribution of neutral hydrogen gas at cosmological distances. Along with the cosmic microwave background, the scale of BAO is one the most powerful probes of cosmological parameters, including dark energy. The main BINGO partners are Brazil, United Kingdom, Switzerland and Uruguay. Assembly will take place in Brazil with most of the components supplied by Brazilian industry. An important motivation for the project is the training of Brazilian engineers, technicians and postdocs in the skills required so that in the future they can get involved in state-of-the-art radio astronomy systems, specially the Square Kilometer Array. This proposal is linked to ``Projeto Temático 2014/07885-0" and contemplates an important contribution to the BINGO system calibration and data analysis pipeline. The work will be conducted at INPE, and will require involvement with the hardware, horns and electronics working groups. It is expected the proponent to be the (or one of the) bridge person between the pipeline software and calibration working groups. This working plan will focus on the construction of the pipeline and the receiver noise characterization and modeling at INPE, during 2018 and early 2019, and data analysis and software adequacy for the science program from early 2019 to early 2021.
