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 ...

But wait; it turns out that the round bottom of a wok is the perfect shape for gathering something else — radio waves, specifically the 21-cm neutral ... the 1420-MHz hydrogen line signal ...

My group uses 21-cm Hydrogen Cosmology to probe the matter-energy content of the early universe. We are creating a data-analysis pipeline to extract low-frequency radio signals from the data to be ...
