A 15 mu m selected sample of high-z starbursts and AGNs
ASTR SOC P 381 (2008) 367-371
Abstract:
We report results from our Spitzer GO-1 program on IRS spectroscopy of a large sample of Luminous Infrared Galaxies and quasars selected from the European Large Area ISO Survey (ELAIS). The selected ELAIS sources have a wide multi-wavelength coverage, including ISOCAM, ISOPHOT, IRAC and MIPS (from SWIRE), and optical photometry. Here we present the sample selection and results from the IRS spectroscopy.Follow-up NIR spectroscopy of ULIRGs observed by ISO
ASTR SOC P 381 (2008) 275-278
Abstract:
We discuss low resolution near-infrared spectroscopy of an unbiased sample of 24 ultraluminous infrared galaxies (ULIRGs), selected from samples previously observed in the mid-infrared with ISO. Qualitatively, the NIR spectra of our 24 ULIRGs resemble those of starbursts. The spectroscopic classification in the NIR is in very good agreement with the MIR. For a subset of our sample for which extinction corrections can be derived from Pace and Br gamma, we find rather high Pa alpha luminosities, in accordance with the powering source of these galaxies being star formation. Furthermore, we identified two unusual objects, the first exhibiting extreme [FeII] emission and the second strong emission in H-2 rotation-vibration emission.IRAC photometric analysis and the mid-IR photometric properties of Lyman-break galaxies
