We present GALEX FUV (1530 A) and NUV (2310 A) observations of the archetypal merging system NGC 4038/39, ``The Antennae". Both tails are relatively bright in the UV, especially in…
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…
