Description:
We present first results of the Hamburg/SAO Survey for Emission-Line
Galaxies (HSS therein, SAO - Special Astrophysical Observatory,
Russia) which is based on the digitized objective-prism photoplates
database of the Hamburg Quasar Survey (HQS). The main goal of this
survey is the search for emission-line galaxies (ELG) in order to
create a new deep sample of blue compact galaxies (BCG) in a large sky
area. Another important goal of this work is to search for new
extremely low-metallicity galaxies. We present the first results of
spectroscopy obtained with the 2.2m telescope at the German-Spanish
Observatory at Calar Alto, and with the 6m telescope at the Russian
Special Astrophysical Observatory. The primary ELG candidate selection
criteria applied were a blue continuum (near 4000Å) and the
presence of emission lines close to 5000A recognized on digitized
prism spectra of galaxies with magnitudes in the range B =16.0-19.5.
The spectroscopy resulted in the detection or/and quantitative
spectral classification of 74 emission-line objects. Of them 55 are
newly discovered, and 19 were already known as galaxies before. 11 of
the latter have redshifts and are known ELGs. For most of the known
galaxies emission line ratios were measured for the first time and an
improved classification is presented. 47 objects are classified as
BCGs, one as Sy2 galaxy, six as probable LINERs, and four as new QSOs.
The remaining galaxies do not show significant Hβ and
[OIII]4959,5007Å emission lines, and are likely either
low-ionization starburst or dwarf amorphous nuclear starburst
galaxies.
