A Gigantic Eruption from the Inner Disk of the Milky Way
Abstract
We have discovered a coherent structure, which seems to be a huge superbubble reaching higher than 3 kpc from the Galactic plane. It has been detected in both Hα and HI and a detailed HI map of it has been produced with the Green Bank Telescope. The total hydrogen mass within the outflow is ≈ 106 M⊙ and its energy content is of order 1053 ergs. At the top of the structure there is a peculiar ``plume'' consisting of more than 104 M⊙ of hydrogen.
