Galaxies can be described as giant cosmic engines that take in gas and
produce stars. Like most engines, however, galaxies perform nowhere near
100 percent efficiency leading to a phenomenon known as stellar quenching.
We believe the key to explaining stellar quenching lies beneath a galaxy's
circulation of mass and energy. Therefore, with the help of brand new high
definition, spatially resolved spectra from the sky survey MaNGA, we
examined, in detail, extraplanar diffuse ionized gas (eDIG) within a large
sample (550) of nearby galaxies in order to determine how various feedback
and accretion processes regulate star formation
