| dc.description | The chance projection of the disk of Mrk~1456 onto a background QSO is similar to the case of SBS 1543+593/HS 1543+5921. Mrk~1456 is a luminous, late-type spiral at z ~ 0.05. Though the QSO, SDSS J114719.90+522923.2 at z ~ 2, has not yet been observed with ultraviolet spectroscopy, it shows strong Ca II absorption at the redshift of Mrk 1456 which gives evidence that it is a possible Damped Lyman Alpha absorber. Spectroscopy of the star-forming nucleus of Mrk~1456 allows us to apply emission-line diagnostics to infer the chemical abundances at the center of the galaxy, and to make a prediction of the expected metallicity on the sightline to the QSO. | |
