Vibrationally Excited HCN around AFGL 2591: A Probe of Protostellar Structure
Todd J. Veach, Christopher E. Groppi, Abigail Hedden
Vibrationally excited molecules with sub-mm rotational transitions are potentially excellent probes of physical conditions near protostars. This study uses observations of the v=1…
Filamentary Accretion Flows in the Embedded Serpens South Protocluster
Helen Kirk, Philip C. Myers, Tyler L. Bourke +3
One puzzle in understanding how stars form in clusters is the source of mass -- is all of the mass in place before the first stars are born, or is there an extended period when the…
Evidence for Dynamically Important Magnetic Fields in Molecular Clouds
Hua-bai Li, Raymond Blundell, Abigail Hedden +3
Recent observational evidence that magnetic fields are dynamically important in molecular clouds, compared to self-gravity and turbulence, is reviewed and illustrated with data fro…
Submillimeter narrow emission lines from the inner envelope of IRC+10216
Nimesh A. Patel, Ken H. Young, Sandra Brünken +8
A spectral-line survey of IRC+10216 in the 345 GHz band has been undertaken with the Submillimeter Array. Although not yet completed, it has already yielded a fairly large sample o…
Arecibo HI Absorption Measurements of Pulsars and the Electron Density at Intermediate Longitudes in the First Galactic Quadrant
J. M. Weisberg, S. Stanimirovic, K. Xilouris +4
We have used the Arecibo telescope to measure the HI absorption spectra of eight pulsars. We show how kinematic distance measurements depend upon the values of the galactic constan…
SuperCam, a 64-pixel heterodyne imaging array for the 870 micron atmospheric window
Christopher Groppi, Christopher Walker, Craig Kulesa +13
We report on the development of SuperCam, a 64 pixel, superheterodyne camera designed for operation in the astrophysically important 870 micron atmospheric window. SuperCam will be…
