We present results obtained with the PRONAOS balloon-borne experiment on interstellar dust. In particular, the submillimeter / millimeter spectral index is found to vary between roughly 1 and 2.5 on small scales (3.5′ resolution). This could have implications for component separation in Cosmic Microwave Background maps.

Some doubts on the validity of the foreground Galactic contribution subtraction from microwave anisotropies
The Galactic foreground contamination in CMBR anisotropies, especially from the dust component, is not easily separable from the cosmological or extragalactic component. In this paper, some doubts


Submillimeter dust emission of the M 17 complex measured with PRONAOS
We map a 50 0 30 0 area in and around the M 17 molecular complex with the French submillimeter balloon-borne telescope PRONAOS, in order to better understand the thermal emission of cosmic dust and
The SCUBA Local Universe Galaxy Survey – II. 450‐μm data: evidence for cold dust in bright IRAS galaxies
This is the second in a series of papers presenting results from the SCUBA Local Universe Galaxy Survey. In our first paper we provided 850-μm flux densities for 104 galaxies selected from the IRAS
Inverse temperature dependence of the dust submillimeter spectral index
We present a compilation of PRONAOS-based results concerning the temperature dependence of the dust submillimeter spectral index, including data from Galactic cirrus, star-forming regions, dust
Submillimeter Mapping and Analysis of Cold Dust Condensations in the Orion M42 Star-forming Complex
We present here the continuum submillimeter maps of the molecular cloud around the M42 Nebula in the Orion region. These have been obtained in four wavelength bands (200, 260, 360, and 580 μm) with
Evolution of dust properties in an interstellar filament
We present submillimetre observations obtained using the balloon-borne experiment PRONAOS/SPM, from 200 to 600  μ m with an angular resolution of 2–3.5′, of a quiescent dense filament (typically
Discovery of a Cold Extended Condensation in the Orion A Complex
The central region of the Orion A cloud complex has been observed in the submillimeter range, using the French balloon-borne 2 m telescope PRONAOS-SPM during its first flight, in 1994 September. An
