Experiments

In April 2017, SANAP launched an experiment on Marion Island called Probing Radio Intensity at high-Z from Marion (PRIZM), searching for signatures of the
hydrogen line The hydrogen line, 21 centimeter line, or H I line is the electromagnetic radiation spectral line that is created by a change in the energy state of neutral hydrogen atoms. This electromagnetic radiation has a precise frequency of , w ...
