摘要:

我们展示了在ESO 3.6 m望远镜上使用EFOSC 2观察到的34个SWIRE-CDFS源样本的光谱。我们已经使用光谱和光谱红移来验证我们的光度红移代码和SED模板拟合方法。我们的12个来源是红外发光星系。其中,5个属于ULIRGs类,1个属于HLIRGs类,有证据表明活动星系核和星暴成分对它们的极红外光度都有贡献,其中3个,星暴贡献1个,活动星系核贡献2个。

英文摘要:

We present the optical spectra of a sample of 34 SWIRE-CDFS sources observed with EFOSC2 on the ESO 3.6m Telescope. We have used the spectra and spectroscopic redshifts to validate our photometric redshift codes and SED template fitting methods. 12 of our sources are Infrared Luminous Galaxies. Of these, five belong to the class of ULIRGs and one to the class of HLIRGs with evidence of both an AGN and starburst component contributing to their extreme infrared luminosity for 3, starburst contributing for 1 and AGN contributing for 2 of them.
