HS 1543+5921 - a bright z = 0.807 QSO in the center of the `Seyfert' galaxy SBS 1543+593.

REIMERS D. and HAGEN H.-J.

Abstract (from CDS):

We show that the `Seyfert' galaxy SBS 1543+593 is a by-chance projection of the center of a nearby galaxy (z=0.009) onto the bright QSO HS 1543+5921 (z=0.807). The quasar has been discovered independently by the Hamburg Quasar Survey, an automated survey for bright QSOs based on digitized objective prism Schmidt plates. Direct imaging and subsequent spectroscopy of a faint (R=22m) HII region in the foreground galaxy allowed to measure the redshift of the galaxy which is a dwarf spiral or irregular galaxy (MR≃-16.8). The galaxy center is located less than 3'' from the QSO. We briefly discuss a possible gravitational lensing effect.
