Abstract

The Advanced, Large, Homogeneous Area, Medium-Band Redshift Astronomical (ALHAMBRA)–Survey is mapping eight different areas in the Northern sky, totalling 4 square degrees, aiming at obtaining a photometric redshift catalogue of over 600,000 galaxies with a median redshift \( \mathop z\limits^ - \, \approx \,0.7 \). This sample will be used to measure cosmic evolution at large, including the processes of galaxy formation and differentiation, large-scale structure, and the history of star formation. The photometric redshift depth, completeness, and accuracy are better than in any previous similar effort, reaching δz ≈ 0. 015(1 + z) for 90% of the objects with AB(I) < 24. We present in this conference the present status of the project, including the observations, data analysis, and the first preliminary scientific results obtained with a small fraction of the total survey.
