Spatially resolved Spitzer-IRS spectral maps of the superwind in M82
Monthly Notices of the Royal Astronomical Society(2015)
Abstract
We have mapped the superwind/halo region of the nearby starburst galaxy M82 in the mid-infrared with Spitzer − IRS. The spectral regions covered include the H2 S(1)–S(3), [Ne II], [Ne III] emission lines and polycyclic aromatic hydrocarbon (PAH) features. We estimate the total warm H2 mass and the kinetic energy of the outflowing warm molecular gas to be between Mwarm ∼ 5 and 17 × 106 M⊙ and EK ∼ ...
