Quasars behind the disk of M31 galaxy

Aims. Our aim is to increase the limited number of quasars behind M 31, necessary for probing the chemical content of the gas and for proper motion reference, with reliable and homogeneous redshift measurements from emission lines. Methods. We carried out spectroscopic follow-up of 32 quasar candida...
