MSX Observations of Diffuse UV Emission in Orion
نویسندگان
چکیده
We have observed intense diffuse radiation in the UV (1400 Å 2600 Å) from three fields around M42 in Orion. Intensities of 20000 photons cm sr s Å were observed to the east and west of M42 with 8000 photons cm sr s Å south of the nebula. Enhanced emission, perhaps associated with a nearby complex of molecular clouds observed in CO, was detected in one of the fields. The IRAS 100 μm emission in that region is highly correlated with the UV intensity with a UV-IR ratio of 40 photons cm sr s Å(MJy sr). In the other two fields there was no structure in the diffuse emission nor was there any correlation with the IRAS emission.

Intense Diffuse Far-UV Emission from the Orion Nebula
We present spectra of the diffuse FUV (900 – 1200 Å) emission from a region near the Orion Nebula: the first high resolution spectra of the diffuse background radiation. These observations were made using serendipitous FUSE observations and were only possible because of the strength of the diffuse emission (≈ 3× 10 photons cm sr s Å) and the sensitivity of the FUSE instrument. Preliminary model...

متن کاملMSX Mid infra red imaging of massive star birth environments . II : Giant H II regions
We present mid-IR (MIR) 21μm images of a complete set of 40 radio selected Galactic giant H II regions from Smith et al., (1978) obtained with the Mid-course Space Experiment (MSX). This wavelength is sampling thermal emission from the ubiquitous dust present within the exciting clusters of OB stars. The spatial morphology often indicates multiple emission sources, suggesting complicated cluste...

We present a study of the high-energy diffuse emission observed toward Orion by the Energetic Gamma-Ray Experiment Telescope (EGRET) on the Compton Gamma-Ray Observatory. The total exposure by EGRET in this region has increased by more than a factor of two since a previous study. A simple model for the diffuse emission adequately fits the data; no significant point sources are detected in the r...
متن کاملThe Large-scale Bipolar Wind in the Galactic Center
During a 9-month campaign (1996–1997), the Midcourse Space Experiment (MSX) satellite mapped the Galactic Plane at mid-infrared wavelengths (4.3–21.3μm). The much greater spatial resolution and sensitivity of the MSX 8.3μm band compared to IRAS at 12μm has revealed diffuse emission not seen before. Here we report evidence for a spectacular limb-brightened, bipolar structure at the Galactic Cent...
