Theoretical Models of Polarized Dust Emission from Protostellar Cores
Paolo Padoan, Alyssa Goodman, Bruce Draine +3
We model the polarized thermal dust emission from protostellar cores that are assembled by super-sonic turbulent flows in molecular clouds. Self-gravitating cores are selected from…
The Mass-Velocity and Position-Velocity Relations in Episodic Outflows
Hector G. Arce, Alyssa A. Goodman
While observational evidence for the episodic nature of young stellar outflows continues to mount, existing numerical and theoretical models of molecular outflows assume they are f…
The Episodic, Precessing Giant Molecular Outflow from IRAS 04239+2436 (HH 300)
Hector G. Arce, Alyssa A. Goodman
We present the first set of detailed molecular line maps of the region associated with the giant Herbig-Haro flow HH 300, from the young star IRAS 04239+2436. Our results indicate…
A New Method to Measure and Map the Gas Scale-Height of Disk Galaxies
Paolo Padoan, Sungeun Kim, Alyssa Goodman +1
We propose a new method to measure and map the gas scale height of nearby disk galaxies. This method is applied successfully to the Australia Telescope Compact Array interferometri…
