Query: CARMA observations of protostellar outflows in NGC 1333   We present observations of outflows in the star-forming region NGC 1333 using
the Combined Array for Research in Millimeter-Wave Astronomy (CARMA). We
combined the 12CO and 13CO (1-0) CARMA mosaics with data from the 14-m Five
College Radio Astronomy Observatory (FCRAO) to probe the central, most dense
and active region of this protostellar cluster at scales from 5'' to 7' (or
1000 AU to 0.5 pc at a distance of 235 pc). We map and identify 12CO outflows,
and along with 13CO data we estimate their mass, momentum and energy. Within
the 7'x7' map, the 5'' resolution allows for a detailed study of morphology and
kinematics of outflows and outflow candidates, some of which were previously
confused with other outflow emission in the region. In total, we identify 22
outflow lobes, as well as 9 dense circumstellar envelopes marked by continuum
emission, of which 6 drive outflows. We calculate a total outflow mass,
momentum and energy within the mapped region of 6 Msun, 19 Msun km/s, and
7x10^44 erg, respectively. Within this same region, we compare outflow
kinematics with turbulence and gravitational energy, and we suggest that
outflows are likely important agents for the maintenance of turbulence in this
region. In the earliest stages of star formation, outflows do not yet
contribute enough energy to totally disrupt the clustered region where most
star formation is happening, but have the potential to do so as the
protostellar sources evolve. Our results can be used to constrain outflow
properties, such as outflow strength, in numerical simulations of
outflow-driven turbulence in clusters.
