Ca II and Na I quasar absorption-line systems in an emission-selected sample of SDSS DR7 Galaxy/Quasar projections. I. Sample selection.

CHERINKA B. and SCHULTE-LADBECK R.E.

Abstract (from CDS):

The aim of this project is to identify low-redshift host galaxies of quasar absorption-line systems by selecting galaxies that are seen in projection onto quasar sightlines. To this end, we use the Seventh Data Release of the Sloan Digital Sky Survey to construct a parent sample of 97,489 galaxy/quasar projections at impact parameters of up to 100 kpc to the foreground galaxy. We then search the quasar spectra for absorption-line systems of Ca II and Na I within ±500 km/s of the galaxy's velocity. This yields 92 Ca II and 16 Na I absorption systems. We find that most of the Ca II and Na I systems are sightlines through the Galactic disk, through high-velocity cloud complexes in our halo, or Virgo Cluster sightlines. Placing constraints on the absorption line rest equivalent width significance ( ≥ 3.0σ), the local standard of rest velocity along the sightline ( ≥ 345 km/s), and the ratio of the impact parameter to the galaxy optical radius ( ≤ 5.0), we identify four absorption-line systems that are associated with low-redshift galaxies at high confidence, consisting of two Ca II systems (one of which also shows Na I) and two Na I systems. These four systems arise in blue, ∼L*rgalaxies. Tables of the 108 absorption systems are provided to facilitate future follow-up.
