Toward a better understanding of the mid-infrared emission in the LMC
D. Paradis, C. Mény, K. Demyk +2
In this paper we aim to constrain for the first time the dust emission in the mid-to-far infrared domain, in the LMC, with the use of the Spitzer IRS and MIPS SED data, combined wi…
Revisiting the dust properties in the molecular clouds of the Large Magellanic Cloud
D. Paradis, C. Mény, M. Juvela +2
In this present analysis we investigate the dust properties associated with the different gas phases (including the ionized phase this time) of the LMC molecular clouds at 1$^{\pri…
Galactic cold cores VI. Dust opacity spectral index
M. Juvela, K. Demyk, Y. Doi +13
The Galactic Cold Cores project has made Herschel observations of 116 fields where the Planck survey has found signs of cold dust emission. The fields contain sources in different…
Modeling and predicting the shape of the far-infrared to submillimeter emission in ultra-compact HII regions and cold clumps
D. Paradis, C. Mény, A. Noriega-Crespo +8
Dust properties are very likely affected by the environment in which dust grains evolve. For instance, some analyses of cold clumps (7 K- 17 K) indicate that the aggregation proces…
Modelling the dust emission from dense interstellar clouds: disentangling the effects of radiative transfer and dust properties
N. Ysard, M. Juvela, K. Demyk +9
With Planck and Herschel, we now have the spectral coverage and angular resolution required to observe dense and cold molecular clouds. As these clouds are optically thick at short…
Detection and characterization of a 500 mic dust emissivity excess in the Galactic Plane using Herschel/Hi-GAL observations
D. Paradis, R. Paladini, A. Noriega-Crespo +7
Past and recent observations have revealed unexpected variations in the FIR-mm dust emissivity. In the Herschel spectral range, those are often referred to as a 500μm emission exce…
Far-Infrared to Millimeter Astrophysical Dust Emission. II: Comparison of the Two-Level Systems (TLS) model with Astronomical Data
D. Paradis, J. -P. Bernard, C. Mény +1
In a previous paper we proposed a new model for the emission by amorphous astronomical dust grains, based on solid-state physics. The model uses a description of the Disordered Cha…
Dust Emissivity Variations In the Milky Way
D. Paradis, J. -Ph. Bernard, C. Meny
Dust properties appear to vary according to the environment in which the dust evolves. Previous observational indications of these variations in the FIR and submm spectral range ar…
