image

ESO111-G014: (a): pointings are overlaid on SuperCOSMOS Bj-band images. (b): star forming regions marked on a GALEX FUV images (again Bj-band image for ESO208-G026). (c): H I moment 0 (intensity) map. Contours are at 0.5, 1.0, 2.5, 5.0, 7.5 M pc−2. (d): stellar kinematics of single star forming regions overlaid on Bj-band image. (e): Hα recession velocities of single star forming regions overlaid on Bj-band image. (f): H I moment 1 (velocity) map. (g): metallicity measurements in single star forming regions overlaid on Bj-band image. (h): radial profileof metallicities with linear fit to the profile, whose slope is the metallicity gradient. The grey dashed line marks the 25 mag arcsec−2 isophotal radius. (i): radial profile of H I column density. Dark blue circles and dashed line show the measured values corrected for inclination. Light blue points and dotted line show the profile rescaled to a 1 M pc−2 isophotal radius if the galaxy had average H I content (for more details see text). The grey dashed line again indicates the 25 mag arcsec−2 isophotal radius. (a)–(g): all seven panels have the same spatial size; north is up and east is left. (d)–(e): colour scale of the velocities is the same in all three panels.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
