Exploring the Cosmic Dark Ages: the Lunar Orbit Array
Date: Friday, December 13th
Time: 2:30 pm - 3:30 pm
Place: Sterling B343 (NOTE NEW LOCATION)
Speaker: Xuelei Chen, National Astronomical Observatories of China/ Chinese Academy of Sciences (NAOC)
Abstract: Radio observations of the redshifted 21 cm line of hydrogen will allow exploration of cosmic epochs before the first luminous objects formed: the epoch of reionization, cosmic dawn, and the cosmic dark ages. This talk will describe the Lunar Orbit Array, a Chinese instrument under study to orbit the Moon to measure the global spectrum of the sky and make sky maps from 1 MHz to 200 MHz, corresponding to redshifts from ~ 1000 to 7.
