A radiation transfer model for the Milky Way. I. Radiation fields and application to high-energy astrophysics. Popescu C.C., Yang R., Tuffs R.J., Natale G., Rushton M., Aharonian F. <Mon. Not. R. Astron. Soc. 470, 2539 (2017)> =2017MNRAS.470.2539P (SIMBAD/NED BibCode)

The library was produced using the axisymmetric radiative transfer model that we have previously implemented to model the panchromatic spectral energy distributions (SEDs) of star-forming galaxies in the nearby universe, but with a new methodology allowing for optimization of the radial and vertical geometry of stellar emissivity and dust opacity, as deduced from the highly resolved emission seen from the vantage point of the Sun. Description: Radiative transfer model calculations of energy density of radiation fields (RFs) in the Milky Way are presented on a cylindrical grid (r,z) sampled at 23x22 positions. There are 15 files of RFs in direct stellar light corresponding to 15 wavelengths in the range 0.0912 to 5 micron and one IDL file containing the radiation fields in the dust emission corresponding to 120 wavelengths in the range 3 to 1000 microns, sampled at the same (r,z) positions.
