Data Breakfast: “The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX): Big Data Challenges”.

This month’s talk is by Devin Crichton, a senior postdoc researcher on HIRAX. Devin will be speaking about:
“The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX):
Big Data Challenges”
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is a radio telescope array to built in the Karoo region of South Africa. The principle goal of this project is to further our understanding of the dominant force driving the expansion of the universe – dark energy. HIRAX will do so by measuring the expansion history of the universe over the time period of 4-11 billion years ago by making use of a particular feature in the radio emission of neutral hydrogen. Additionally, by making real-time observations of the radio sky, HIRAX will detect and monitor radio transients such as pulsars and Fast Radio Bursts (FRBs), extremely energetic extra-galactic signals of as yet undetermined origin. These goals pose a significant big data challenge: HIRAX’s incoming data rate will be comparable to the consumer internet bandwidth of a large city and the first stage processed data will accumulate at 100s of terabytes per day. This must be significantly compressed to make storage feasible. In this talk I will introduce the HIRAX project with particular emphasis on the challenges it faces in processing this large data set and the hardware and software techniques being used to overcome them.
The event will be held in the Senate Chamber on UKZN Westville Campus. It can be found at point A1 on the map below.
