Visible image of a pair of colliding galaxies collectively called NGC 3256

Composite visible and infrared view of the colliding galaxies, NGC 4038/NGC 4039, which make up the "Antennae" system

GEco: Galactic ecology of the dynamic ism


  • Spectral mapping of fine structure and mid-/high-excitation CO lines as diagnostics of physical conditions and motions of interstellar clouds.  For background information, see white paper and the decadal review 2020 white paper.

    − Lines trace coolants in range environments where stars and planets form.
    − Maps at (15”× λ/350μm) resolution over degree scales of Milky Way including Galactic Center and Magellanic Clouds
       (low metallicity).
    − High site provides unique access to shortest wavelength.
    − Builds on SOFIA (2.5m) with better resolution, much more observing time.
