  1. 3D Visualization and Detection of Outflows From Young Stars Michelle Borkin Hector Arce, Alyssa Goodman, & Mike Halle ADASS 2007 Conference - September 25, 2007

  2. Outflows HH knots HH jet Outflow lobes Protostar ~ 1pc MolecularCloud Note: not drawn to scale. Based on H. Arce Thesis 2001.

  3. Outflows across wavelengths… HH knots far from source mark the ends of bipolar “jets” or “outflows” Stanke, McCaughrean & Zinnecker, 1999

  4. How to find outflows in radio cubes… Examining individual spectra… Examining individual slices…

  5. 3D Visualization

  6. A Survey of Velocity Features in Perseus Visualize 12CO data cube in 3D Slicer Mark high velocity points in 3D space, and export to astronomical software Identify outflows and calculate statistics

  7. Outflow Identification DEC RA RA-DEC integrated map of 12CO Velocity

  8. Outflow Identification 12CO data beam size And many more… Red Shifted points HH Objects Known Outflow Sources IRAS Sources c2d Sources Blue Shifted points

  9. Perseus Outflows New outflows Known outflows Many small known outflows Outflow extensions Initial results: • 35 new potential outflows • 4 extensions on known outflows Also 7 potential new shells interacting with the cloud… IRAS Sources Red Shifted points Known Outflow Sources Blue Shifted points HH Objects Borkin, et al. 2007 in prep

  10. Perseus Shells

  11. Next step: segmentation
