Abstract:Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) is photometric survey designed to trace the cosmic evolution and cosmic variance. It covers a large area of ~4deg^2^ in eight fields, where seven fields overlap with other surveys, allowing us to have complementary data in other wavelengths. All observations were carried out in 20 continuous, medium band (30nm width) optical and 3 near-infrared (JHK) bands, providing the precise measurements of photometric redshifts. In addition, morphological classification of galaxies is crucial for any kind of galaxy formation and cosmic evolution studies, providing the information about star formation histories, their environment and interactions, internal perturbations, ...(more)
Abstract: (hide)
The ALH observations were carried out at the Calar Alto German-Spanish Astronomical Center (CAHA3), under the Spanish guaranteed time of 110 nights. Eight fields were observed in the Northern hemisphere sky, having a seeing lower than 1.6arcsec (ranging mainly between 0.8 and 1.2arcsec). Each ALH detection was observed in 23 bands, with 20 optical and three standard JHK NIR filters.
