Spatially Resolved Circumgalactic Medium around a Star-forming Galaxy Driving a Galactic Outflow at z ≈ 0.8

We report the small-scale spatial variation in cool ( T  ∼ 10 ^4 K) Mg ii absorption detected in the circumgalactic medium (CGM) of a star-forming galaxy at z  ≈ 0.8. The CGM of this galaxy is probed by a spatially extended bright background gravitationally lensed arc at z = 2.76. The background arc...
