摘要

We present sensitive 2.1 and 3.3?cm Jansky Very Large Array radio continuum observations of the region IC?348?SW. We detect a total of 10 compact radio sources in the region, 7 of which are first reported here. One of the sources is associated with the remarkable periodic time-variable infrared source LRLL 54361, opening the possibility of monitoring this object at radio wavelengths. Four of the sources appear to be powering outflows in the region, including HH?211 and HH?797. In the case of the rotating outflow HH?797, we detect a double radio source at its center, separated by ~3''. Two of the sources are associated with infrared stars that possibly have gyrosynchrotron emission produced in active magnetospheres. Finally, three of the sources are interpreted as background objects.
