The Connection between a Lyman Limit System, a very strong OVI Absorber, and Galaxies at z~0.203

N. Lehner, J. X. Prochaska, H. A. Kobulnicky +4

With a column density log N(OVI) = 14.95+/-0.05, the OVI absorber at z_abs~0.2028 observed toward the QSO PKS0312-77 (z_em=0.223) is the strongest yet detected at z<0.5. At nearly…
