THE DUSTY YOUNG UNIVERSE:
PHOTOMETRY AND SPECTROSCOPY OF QUASARS AT z > 2
First Results
Here we present our first results obtained from
the Spitzer IRAC and MIPS observations of our Hersche sample. All data have been
taken and the preliminary analysis shows that all targeted QSOs have been
detected in IRAC channel 1-4 and - with the excpetion of a few sources - also in
the MIPS 24 μm observations:
-
SDSS J0338+0021 @ z = 5.03 and z-mag(AB) = 19.70
color comp.: IRAC3.6,4.5,5.8
-
SDSS J161705.69+443522.6 @ z = 5.49 and z-mag(AB) = 18.58
color comp.: IRAC3.6,4.5,5.8
-
PKS1937-101 @ z = 3.79 (from the radio/mm-loud QSO sample) and Opt-mag(AB)=19.0
color comp.: IRAC3.6,4.5,5.8
