It got a bit lost with everything else going on this week, but my (high school!) research student, Jack, has been working with me on building a low-cost home radio telescope to map Galactic 21 cm features, and his tutorial for others to do the same is now up on arXiv:

Galactic Neutral Hydrogen Structures Spectroscopy and Kinematics: Designing a Home Radio Telescope for 21 cm Emission
This study presents the methodology for creating a cost-efficient radio astronomy telescope that can be used to detect 21 cm emissions (1420.405 MHz) and determine the distribution and kinematics of neutral hydrogen specifically in the Milky Way.arXiv.org
