Spitzer imaging of i '-drop galaxies: old stars at z approximate to 6

We present new evidence for mature stellar populations with ages >100 Myr in massive galaxies (M stellar > 10 10 M ⊙) seen at a time when the Universe was less than 1 Gyr old. We analyse the prominent detections of two z ≈ 6 star-forming galaxies (SBM03#1 and #3) made at wavelengths co...
