Scientific paper

As part of the COMPLETE Survey of Star Forming Regions, we have recently made extensive maps of 12CO and 13CO emission in the Perseus molecular cloud complex. The maps cover an area of almost 4 sq. degrees and contain 150,000 spectra each. These data provide unprecedented spectral and spatial resolution on such large scales and have extremely high dynamic range, enabling us to detect structures which have been missed by previous molecular line maps of the region.
We have been experimenting with various ways to visualise and characterise the complex structure which is revealed by the maps, including new outflows, shells, ``fingers" and ``holes." Here we present a snapshot of some of these structures, and discuss their possible origin.
