Hot galactic gas and narrow line quasar absorption systems

Observations of the hot interstellar gas (T ≫ 104 K) are numerous and imply that the temperatures of substantial amounts of the disk gas to be 2–3 × 105 K and of the halo gas to be 8 × 104 K, but the theoretical models to explain the properties of both the disk and the halo hot gas seem to be in need of some refinement. Observations of the quasar narrow… CONTINUE READING
