The Cgm At Cosmic Noon With Kcwi: Outflows From A Star-Forming Galaxy At Z=2.071

We present the first results from our "CGM at Cosmic Noon with KCWI" program to study gas flows in the circumgalactic medium (CGM) at z = 2-3. Combining the power of a high-resolution VLT/UVES quasar spectrum, a Hubble Space Telescope/Advanced Camera for Surveys image, and integral field spectroscopy with Keck/KCWI (Keck Cosmic Web Imager), we detected Ly alpha emission from a 1.7L(*) galaxy at z(gal) = 2.0711 associated with a Lyman limit system with weak Mg ii (W-r(2796) = 0.24 A) in quasar field J143040+014939. The galaxy is star-forming (SFRFUV = 37.8 M_More
