FOUR IRAC SOURCES WITH AN EXTREMELY RED H - [3.6] COLOR: PASSIVE OR DUSTY GALAXIES AT z > 4.5?

Abstract:

We report the detection of four IRAC sources in the GOODS-South field with an extremely red color of H - [3.6] > 4.5. The four sources are not detected in the deep Hubble Space Telescope WFC3 H-band image with H limit = 28.3mag. We find that only three types of SED templates can produce such a red H - [3.6] color: a very dusty SED with the Calzetti extinction of AV = 16mag at z = 0.8; a very dusty SED with the SMC extinction of AV = 8mag at z = 2.0- 2.2; and an 1Gyr SSP with AV ∼0.8 at z =...
