Fig. 2: Declining radial profile of high-ion absorption.
Sum total of O VI (yellow triangles), C IV (pink circles) and Si IV (orange squares) column density of Magellanic velocity absorbers that are not photoionized in each sightline as a function of LMC impact parameter, ρLMC, with open symbols marking upper limits. The best-fit line and 68% confidence intervals for all data (dotted lines) and only data at ρLMC > 7 kpc (solid lines) are also shown (see Methods). Error bars represent standard deviations.
