A Census of Protostellar Outflows in Nearby Molecular Clouds
  We adopt the deep learning method CASI-3D (Convolutional Approach to
Structure Identification-3D) to systemically identify protostellar outflows in
12CO and 13CO observations of the nearby molecular clouds, Ophiuchus, Taurus,
Perseus and Orion. The total outflow masses are 267 Msun, 795 Msun, 1305 Msun
and 6332 Msun for Ophiuchus, Taurus, Perseus and Orion, respectively. We show
the outflow mass in each cloud is linearly proportional to the total number of
young stellar objects. The estimated total 3D deprojected outflow energies are
9e45 ergs, 6e46 ergs, 1.2e47 ergs and 6e47 ergs for Ophiuchus, Taurus, Perseus
and Orion, respectively. The energy associated with outflows is sufficient to
offset turbulent dissipation at the current epoch for all four clouds. All
clouds also exhibit a break point in the spatial power spectrum of the outflow
prediction map, which likely corresponds to the typical outflow mass and energy
injection scale.
