HAWC+/SOFIA Observations of OMC-1: Spectral Energy Distributions

Date:

The Orion Molecular Cloud-1, OMC-1, has been well-studied as an example of a region that is actively forming massive stars. The High-resolution Airborne Wideband Camera+, HAWC+, on the SOFIA telescope has observed this region polarimetrically and photometrically at wavelengths of 53, 89, 154, and 214 microns. These new data will help determine the role of magnetic fields in the dynamics of the region. Combining the photometry from HAWC+ with other far-infrared, submillimeter and radio maps, we produce new spectral energy distributions across a ~5-arcminute region from ~50 microns to 3.5 cm. We fit the intensity with a single-temperature modified blackbody and a free-free component that contributes at long wavelengths. We present the resulting maps of temperature, column density and dust emissivity index at 19-arcsecond resolution.
