PHL 1226 and IC 1746 - A QSO-galaxy pair without Ca II or Na I absorption
Description
Spectroscopic observations of the QSO PHL 1226 show no absorption lines at the expected wavelengths of Ca II H and K and Na I D absorption at the redshift of the nearby galaxy IC 1746 (z = 0.0176). The line of sight to PHL 1226 intercepts IC 1746 near the galaxy major axis at a projected separation from the galaxy nucleus of 28/h50 kpc. The 3-sigma upper limits on equivalent width attained in the spectra are 110 mA for Ca II H or K and 90 mA for either of the Na I D lines. The probable Ca II K line reported by Bergeron et al. (1988) is not confirmed. 18 refs
