Researchers from the International Centre for Radio
Astronomy Research (ICRAR) have proven a new technique that will provide a
clearer picture of the Universe’s history and be used with the next generation
of radio telescopes such as the Square Kilometre Array (SKA).
In research published today in the Monthly Notices of the
Royal Astronomical Society, ICRAR PhD Candidate Jacinta Delhaize has studied
distant galaxies en masse to determine one of their important properties – how
much hydrogen they contain – by ‘stacking’ their signals.
