The Relationship Between Galaxy ISM and Circumgalactic Gas Metallicities

10 Oct 2019 Kacprzak Glenn G. Pointon Stephanie K. Nielsen Nikole M. Churchill Christopher W. Muzahid Sowgat Charlton Jane C.

We present ISM and CGM metallicities for 25 absorption systems associated with isolated star-forming galaxies (<z>=0.28) with 9.4<log(M*/Msun)<10.9 and with absorption detected within 200kpc. Galaxy ISM metallicities were measured using Ha/[NII] emission lines from Keck/ESI spectra... (read more)
