Query: Exploring AGN - starburst coexistence in galaxies at z$\sim$ 0.8 by the
  [OIII]4959+5007/[OIII]4363 line ratio   We analyze by detailed modelling the spectra observed from the sample
galaxies at z$\sim$0.8 presented by Ly et al (2015), constraining the models by
the [OIII]5007+4959/[OIII]4363 line ratios. Composite models accounting for
shock and photoionization by AGN or starburst are adopted. O/H are about solar
for all the objects, except for a few AGN clouds with O/H= 0.3 -0.5 solar.
Starburst models reproduce most of the data within the observational errors.
About half of the object spectra are well fitted by an accreting AGN. Some
galaxies show multiple radiation sources, such as starburst+AGN, or a double
AGN.
