Gas dynamics in the galaxy
WebMar 9, 2008 · In particular, clouds of interstellar gas that would other-wise hide optical features in our galaxy can reveal much about general galactic structure and dynamics if we look in a frequency band around 1420.4 MHz. This is known as the 21 cm line. Emitted by neutral hydrogen atoms, this line can be seen with varying intensity coming from WebMar 14, 2024 · Its normalization is lower by a factor of ∼2, in agreement with estimates of warm-hot gas making up the remaining difference. We compute baryonic collapse efficiency with the halo mass calculated two ways, via halo abundance matching (HAM) and via dynamics (extended all the way to three-galaxy groups using stacking).
