摘要:

我们目前最大的光谱后续进行SWIRE ELAIS-N1。我们能够确定289个河外星系源的红移。后者的光谱红移的值进行了比较,从我们的光度红移代码的估计值与两者之间的星系和类星体非常好的协议。六个类星体是超亮红外星系,它们都是宽线活动星系核。我们已经进行了30个源的发射线诊断,以便将它们分类为恒星形成,Seyferts,复合材料和LINER,并将结果与我们的SED模板拟合方法和中红外选择方法的预测进行比较。

英文摘要:

We present the largest spectroscopic follow-up performed in SWIRE ELAIS-N1. We were able to determine redshifts for 289 extragalactic sources. The values of spectroscopic redshifts of the latter have been compared with the estimated values from our photometric redshift code with very good agreement between the two for both galaxies and quasars. Six of the quasars are hyperluminous infrared galaxies all of which are broad line AGN. We have performed emission line diagnostics for 30 sources in order to classify them into star-forming, Seyferts, composite and LINER and compare the results to the predictions from our SED template fitting methods and mid-IR selection methods.
