| Abstract: | We carried out the direct measurement of the fraction of dusty sources in a sample of extremely red galaxies with (R-Ks) ≥ 5.3 mag and Ks<20.2 mag, using 24µm mid infrared data from the Spitzer Space Telescope. Combining deep 24µm, Ks- and R-band data over an area of ~64 sq.arcmin in the ELAIS N1 field of the Spitzer First Look Survey (FLS), we find that 50±60% of our ERO sample have measurable 24µm flux above the 3σ flux flux limit of 40µJy. This flux limit corresponds to a SFR of 12 Mө/yr at z~1, much more sensitive than any precious long wavelength measurement... |
