  • the neutral hydrogen (H i) in the interstellar medium (ISM) is in two phases - a warm and a cold phase.
  • The warm neutral medium (WNM) has typical temperatures of ∼ 10000 K
  • he cold neutral medium (CNM) has typical temperatures < 300 K (20-50%)
  • The WNM is mostly detected in emission and the CNM in absorption.
