Abstract:
We present results on low-resolution mid-infrared (MIR) spectra of 70
IR-luminous galaxies obtained with the infrared spectrograph (IRS)
onboard Spitzer. We selected sources from the European Large Area
Infrared Survey with S15>0.8mJy and photometric or spectroscopic
z>1. About half of the samples are quasi-stellar objects (QSOs) in the
optical, while the remaining sources are galaxies, comprising both
obscured active galactic nuclei (AGN) and starbursts. Redshifts were
obtained from optical spectroscopy, photometric redshifts and the IRS
spectra. The later turn out to be reliable for obscured and/or
star-forming sources, thus becoming an ideal complement to optical
spectroscopy for redshift estimation.
Description:
All targets were observed in the two low-resolution modules of the
IRS, short low (SL) and long low (LL), exposing the two subslits on
each of them (SL1, SL2, LL1 and LL2) and thus covering the 5-38um
range.
