Quasars

In the course of our follow-up spectroscopy six QSOs were discovered with a strong emission line in the wavelength region between 5000 Å and the sensitivity break of the Kodak IIIa-J photoemulsion near 5400 Å. For all of them it was Ly$\alpha$$\lambda$1216 redshifted to z $\sim$ 3. This strong line produces an easily visible emission peak in the digitized prism spectra even for very faint objects (B $\sim 19\fm0 - 20\fm0$) which is hard to distinguish from low-redshifted [O III] features. In other cases QSOs normally were not selected as candidates for follow-up spectroscopy.

The data for these six new high-redshift quasars are presented in Table 3. Their finding charts and plots of spectra can be found on www-site of the Hamburg Quasar Survey (http://www.hs.uni-hamburg.de/hqs.html).
