High Spatial Resolution Observations of Two Young Protostars in the R Corona Australis Region
Christopher E. Groppi, Todd R. Hunter, Raymond Blundell +1
We present multi-wavelength, high spatial resolution imaging of the IRS 7 region in the R Corona Australis molecular cloud. Our observations include 1.1 mm continuum and HCO^+ J =…
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…
Star Formation in the Northern Cloud Complex of NGC 2264
Abigail S. Hedden, Christopher K. Walker, Christopher E. Groppi +1
We have made continuum and spectral line observations of several outflow sources in the Mon OB1 dark cloud (NGC 2264) using the Heinrich Hertz Telescope (HHT) and ARO 12m millimete…
Warm-Dense Molecular Gas in the ISM of Starbursts, LIRGs and ULIRGs
Desika Narayanan, Christopher K. Walker, Christopher E. Groppi
The role of star formation in luminous and ultraluminous infrared galaxies is a hotly debated issue: while it is clear that starbursts play a large role in powering the IR luminosi…
Millimeter and Submillimeter Survey of the R Corona Australis Region
Christopher Groppi, Craig Kulesa, Christopher Walker +1
Using a combination of data from the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO), the Arizona Radio Observatory Kitt Peak 12m telescope and the Arizona Radio…
Testing the AGN-Starburst Connection in Seyfert Galaxies
Valentin D. Ivanov, George H. Rieke, Christopher E. Groppi +3
We use the CO band at 2.3 micron to constrain the populations of young stars in the central regions of Seyfert galaxies. We report new CO band spectroscopy of 46 Seyfert galaxies.…
