Next: The APM selected sample Up: Second priority candidates Previous: Second priority candidates . From the random selected subsample of second priority candidates we observed twenty six objects during the 6-m telescope runs (mainly those with R.A.< 11 h ) along with the observations of first priority targets. Altogether we found 12 emission-line objects: one appeared to be a QSO with z =3.15, and the rest are various types of ELGs. ... One object is an absorption-line galaxy. ...

... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...
