Inspired by yesterday's ADAP of the
Magnetic and gaseous
spiral arms in M83 (Frick et al. 2015), here we show its neutral hydrogen
distribution. - (Left) Large-scale
moment-0 map of the extended HI gas distribution, constructed from mosaic data
obtained with both the 21-cm multibeam system on the 64-m Parkes dish and the
Australia Telescope Compact Array (ATCA). - (Right) ATCA high-resolution HI
moment-0 map (red contours) overlaid onto the WISE 12 micron map (grey-scale,
log-stretch) of the central disk (denoted with a grey box in the left panel).
The HI contour levels are 0.1, 0.27, 0.43 and 0.6 Jy/beam km/s. The ATCA beam
is approx. 10 arcsec. - Reference: Figure 14 in Constructing a WISE
