The Magellanic Stream in zenithal equal-area coordinates: (a) observed H I data for the Magellanic Stream, with the line-of-sight velocity indicated by the color scale and the relative gas column density indicated by the brightness; the points represent the sightlines with ultraviolet-absorption-line observations from the NASA/ESA Hubble Space Telescope, colored by their line-of-sight velocity; these points show the extent of the ionized gas associated with the stream; (b) the results of the model including the Magellanic Corona and the Milky Way’s hot corona; gas originating in the disks of the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) is shown in the model, without separating neutral gas from ionized gas; this affects the morphology of the stream, causing the model to appear smoother and less fragmented than the data; however, the model reproduces the current spatial location and velocity of both clouds, and the velocity gradient of the gas along the stream; the Milky Way disk and background are extracted from real H I images.

Huge Halo of Warm Gas around Magellanic Clouds is Key to Formation of Magellanic Stream

Sep 9, 2020 by News Staff

A team of astronomers from Australia and the United States has found that a halo of warm ionized gas surrounding the Large and Small Magellanic Clouds...
