The z=0.558 absorption system towards PKS 0118-272: A candidate Damped LY α system at low redshift.
We present a study of the MgII absorption system at z=0.558 towards the BL Lac object PKS 0118-272 based on high resolution spectra (λ/{DELTA}λ=~2x10^4^) obtained at the 3.6m ESO telescope and on direct imaging data obtained at the 3.5m ESO New Technology Telescope. At the redshift of the absorber we detect lines of the low ionization species MgI
