HERA - Hydrogen Epoch of Reionization Array


Program Description: The Hydrogen Epoch of Reionization Array (HERA) program aims to answer the primary questions: what objects first lit up the Universe and reionized the neutral IGM? Over what redshift range did this occur? How did the process proceed, leading to the large scale galaxy structure seen today? In Phase I, Sister telescopes Murchison Widefield Array (MWA) and Precision Array for Probing the Epoch of Reionization (PAPER) are opening this new observational window on the early universe. They have shown that, careful design and new analysis techniques, foregrounds and systematics can be overcome and are now primarily limited by collecting area. In Phase II a single array combining experience gleaned from these two arrays will be capable of making higher SNR measurements in much less time. Phase I is in progress. PAPER is located in South Africa

Data Description: The Murchison Widefi eld Array (MWA) is a low-frequency radio telescope operating between 80 and 300 MHz. It is located at the Murchison Radio-astronomy Observatory (MRO) in Western Australia, the planned site of the future Square Kilometre Array (SKA) lowband telescope, and is one of three telescopes designated as a Precursor for the SKA. The Precision Array for Probing the Epoch of Reionization (PAPER) is a low-frequency radio interferometer designed to detect the ignition of the first stars and galaxies around 500 Million years after the Big Bang. It uses intensity mapping of 21cm emission of neutral hydrogen at high redshifts (z=7-12) to measure the power spectrum of fluctuations in the intergalactic medium introduced by the first luminous sources in the universe.
