Spectral index variations of galactic emission
(Copernicus GmbH, Katlenburg-Lindau, 2004-12)
We have used all-sky maps at 45 MHz, 408 MHz, 1420 MHz and 22.8 GHz to calculate the distribution of spectral indices across the sky. This requires an adjustment of the adopted zero-levels of the different surveys, which ...
Unusual Galactic HiiRegions at the Intersection of the Central Molecular Zone and the Far Dust Lane
(IOP Publishing, 2020)
Sgr.E is a massive star formation complex found toward the Galactic center that consists of numerous discrete, compact H II regions. It is located at the intersection between the central molecular zone (CMZ) and the far ...
The Galactic disc distribution of planetary nebulae with warm dust emission features - I
(BLACKWELL SCIENCE LTD, 2001-02-01)
We investigate the Galactic disc distribution of a sample of planetary nebulae characterized in terms of their mid-infrared spectral features. The total number of Galactic disc PNe with 8-13 mum spectra is brought up to ...
Distance limits on the bright X-ray emission toward the Galactic center: Evidence for a very hot interstellar medium in the Galactic X-ray bulge
(UNIV CHICAGO PRESS, 2000-12-10)
Observations of the diffuse X-ray background at energies similar to3/4 and 1.5 keV show a large region of enhanced emission around the Galactic center. The origin of this X-ray enhancement is not known, but the best ...
