Astronomers Debate Why Radio Science Measures in Energy per Hertz

Radio and radar astronomer Michael Busch says a question from science writer Dan Falk confounds astronomers: measurements are conventionally given as energy per hertz of spectrum, rather than in straight energy terms. He notes infrared astronomers complicate things further by quoting values in inverse centimeters. The exchange has become a small talking point about inconsistent unit conventions across astronomy subfields.
Why now: An astronomer publicly highlighted the confusing unit conventions that differ across radio and infrared astronomy.

Evidence
- This question confounds every radio and radar astronomer, because we always measure things in terms of energy per Hz (or per kHz or MHz or GHz) of spectrum. Although the infrared astronomers sometimes insist on doing things in inverse centimeters. That confuses me. QT Dan Falk… · michael_w_busch@mastodon.online · 1
