Type of Event (for grouping events):
Feedback from star formation and supernovae explosions are known to regulate the star formation in galaxies and help re-distribute metals in and around galaxies. However, the exact process of how to couple the energy to the ISM, how to drive an outflow, and how giant molecular clouds get destroyed are still not well understood. To make progress, we need to obtain large areal coverage integral field spectroscopy with sufficient resolution on the star-forming regions in the Milky Way and local group galaxies. To make such observations possible, we need to significant reduce the cost of the spectrographs, which typically costs millions of dollars to build. I will introduce a new instrument concept that will help reduce the cost of a spectrograph significantly. When using multiple such spectrographs, paired with multiple small telescopes, we can significantly exceed the performance of traditional spectrographs under similar total cost. We plan to build a large number of these systems and make it possible to conduct an all-sky integral field spectroscopy survey with high spectral resolution greater than R~10,000.
