Dust Emission in Galaxies at Millimeter Wavelengths: Cooling of star forming regions in NGC6946
G. Ejlali, R. Adam, P. Ade +54
Interstellar dust plays an important role in the formation of molecular gas and the heating and cooling of the interstellar medium. The spatial distribution of the mm-wavelength du…
Galactic star formation with NIKA2 (GASTON): Filament convergence and its link to star formation
N. Peretto, R. Adam, P. Ade +45
In the past decade filaments have been recognised as a major structural element of the interstellar medium, the densest of these filaments hosting the formation of most stars. In s…
