Fig. 3: 3D dust density structure of the Eos cloud.
From: A nearby dark molecular cloud in the Local Bubble revealed via H2 fluorescence
Top: two-dimensional slices of the cloud at different distances. The colour bar indicates both the total dust extinction density and the total mass density, assuming dust properties from ref. 29 and a gas-to-dust mass ratio of 124. As in Fig. 1, the magenta contour shows the region with high H2/FUV ratio. Bottom left: Dustribution density for b = 55°. The two red lines indicate the minimum and maximum extents of the magenta contour in Fig. 2, and the cyan and green dashed lines indicate the extent of the Local Bubble at this latitude (from refs. 58 and 59 respectively). Bottom right: projected view of the Eos cloud isosurface and surroundings relative to Local Bubble models. There is no indication of other clouds in the same direction. The 3D dust density of the solar neighbourhood highlighting the Eos cloud and the Local Bubble models can be viewed at links provided in the Data availability section.
