Ground-Breaking Science And Spectacular Cosmic Images From The PAPER Instrument In The Karoo


Scientific studies done with the “PAPER” array, one of the world-class scientific instruments in South Africa’s Karoo Radio Astronomy Reserve, is producing ground-breaking science and spectacular cosmic images, resulting in several important articles in top astronomy journals.

The primary goal of PAPER (Precision Array to Probe the Epoch of Reionization) is to detect emission from the neutral gas that pervaded the universe before the first galaxies and black holes were formed. This ‘epoch of reionization’, as it is called, is the last frontier in observational cosmology.

Recent observations with PAPER were used to set the first physically interesting limits on emission from the neutral hydrogen during this key epoch in cosmic structure formation. Besides providing important constraints on the very early evolution of the universe, the PAPER observations are helping to define the techniques and instrumentation that will translate into the design of a next generation ‘Hydrogen Epoch of Reionization Array’ (HERA), and eventually, the low-frequency SKA.
