Dust Heating Sources in Galaxies: The Case of M33 (HERM33ES)
Boquien, M.; Calzetti, D.; van der Werf, P. +8 more
Dust emission is one of the main windows to the physics of galaxies and to star formation as the radiation from young, hot stars is absorbed by the dust and reemitted at longer wavelengths. The recently launched Herschel satellite now provides a view of dust emission in the far-infrared at an unequaled resolution and quality up to 500 µm. In…
The Galactic Center in the Far-infrared
Smith, Howard A.; Stark, A. A.; González-Alfonso, E. +2 more
We analyze the far-infrared dust emission from the Galactic center region, including the circumnuclear disk (CND) and other structures, using Herschel PACS and SPIRE photometric observations. These Herschel data are complemented by unpublished observations by the Infrared Space Observatory Long Wavelength Spectrometer (ISO-LWS), which used paralle…
