A comparative study of the spatial distribution of ultraviolet and far-infrared fluxes from M 101
C. C. Popescu, R. J. Tuffs, B. F. Madore +23
The total ultraviolet (UV) flux (from 1412 to 2718 AA) of M 101 is compared on a pixel-to-pixel basis with the total far-infrared (FIR) flux (from 60 to 170 micron), using the maps…
Far-infrared and sub-mm observations of the Crab nebula
D. A. Green, R. J. Tuffs, C. C. Popescu
We present FIR and sub-mm images of the Crab nebula, taken with ISOPHOT on board ISO and with the SCUBA on the JCMT. The ISOPHOT observations were made at 60, 100, 170 micron, with…
Modelling the Pan-Spectral Energy Distribution of Starburst Galaxies: I. The role of ISM pressure & the Molecular Cloud Dissipation Timescale
Michael Dopita, Brent Groves, Joerg Fischera +6
In this paper, we combine the stellar spectral synthesis code STARBURST 99, the nebular modelling code MAPPINGS IIIq, a 1-D dynamical evolution model of \HII regions around massive…
Modelling the spectral energy distribution of galaxies. III. Attenuation of stellar light in spiral galaxies
Richard. J. Tuffs, Cristina C. Popescu, Heinrich J. Voelk +2
We present new calculations of the attenuation of stellar light from spiral galaxies using geometries for stars and dust which can reproduce the entire spectral energy distribution…
