Tracing Metals in Nearby Dwarf Galaxies

Yong Zheng, Rensselaer Polytechnic Institute (RPI)

Modern hydrodynamical simulations show that stellar feedback in dwarf galaxies can drive large quantities of metals out of the galaxies following episodes of star formation. And these metals may now be retained in the circumgalactic medium (CGM) or have lost to the vast intergalactic medium. In this talk, I'll show recent progress to consistently assess the retention rate of metals in the CGM of nearby dwarf galaxies. I will also discuss observational efforts to capture metals flowing out of dwarf galaxies in action and quantify the relation between outflows and stellar feedback strength at a low-mass regime.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
