What do you get when you put a one-meter parabolic dish, an SDR, a Raspberry Pi, and an H1-LNA for 21 cm emissions together? The answer is: a radio telescope that can track hydrogen in the Milky ...

My current research concerns Dark Cosmology or studying Dark matter in the Dark Ages of the universe. My group uses 21-cm Hydrogen Cosmology to probe the matter-energy content of the early universe.

IT is usually considered that molecular hydrogen does not have an infra-red rotation-vibration spectrum. However, such a spectrum may be expected as a forbidden transition made possible by the ...

IN view of the considerable attention given to the secondary spectrum of hydrogen in recent investigations, it may be worth announcing that this spectrum has been extended photographically so far ...
