Abstract

The temperature predicted by photoionization models for the narrow line region of Seyfert 2 galaxies is lower than the value inferred from the observed [OIII] λ4363Å/λ5007Å line ratio. We explore the possibility of considering a harder ionizing continuum than typically assumed. The spectral ionizing energy distribution, which can generate the observed λ4363Å/λ5007Å ratio, is characterized by a secondary continuum peak at 200 eV.

SEYFERT星系的最佳光谱能量分布

由光电离模型预测的Seyfert 2星系窄线区域的温度低于由观测到的[OIII] λ4363Å/λ5007Å线比推断的值。我们探索考虑比通常假设的更硬的电离连续体的可能性。光谱电离能分布在200 eV处出现二次连续峰，可产生观测到的λ4363Å/λ5007Å比值。
