Abstract (from CDS):

begin{HTML} We discuss the observational properties of strong emission-line galaxies at low redshifts found by our deep imaging survey for high-redshift Lya emitters. In our survey, we used a narrow-band filter, <I>NB816</I> (l<sub>center</sub> = 8150 Å with FWHM = 120 Å), and an intermediate-band filter, <I>IA827</I> (l<sub>center</sub> = 8270Å with FWHM = 340 Å). In this survey, 62 <I>NB816</I>-excess (> 0.9mag) and 21 <I>IA827</I>-excess (> 0.8mag) objects were found. Among them, we found 20 <I>NB816</I>-excess and 4 <I>IA827</I>-excess Lya emitter candidates. Therefore, it turns out that 42 <I>NB816</EMAIL>)-excess and 17 <I>IA827</I>-excess objects are strong emission-line objects at lower redshifts. Since 4 objects in the two low-z samples are common, the total number of strong low-z emitters is 55. Applying our photometric redshift technique, we identified 7 Ha emitters at z ~0.24, 20 Hb-[O <FONT SIZE="-2">III</FONT> ] ones at z ~0.65, and 11 [O <FONT SIZE="-2">II</FONT> ] ones at z ~1.19. However, we could not determine reliable photometric redshifts of the remaining 17 emitters. The distributions of their rest frame equivalent widths are consistently understood based on recent studies of galaxy evolution from z ∼ 1 to z ∼ 0.
