We present near-IR (J and Ks) number counts and colors of galaxies detected in deep VLT-ISAAC images centered on the Chandra Deep Field and Hubble Deep Field-South for a total area of 13.6 arcmin. The limiting surface brightness obtained is Ks≃22.8 mag/arcsec and J≃24.5 (1σ) on both fields. A dlogN/dm relation with a slope of ∼ 0.34 in J and ∼ 0.28 in Ks is found in both fields with no evidence of decline near the magnitude limit. The median J-Ks color of galaxies becomes bluer at magnitudes… CONTINUE READING
