The most detailed catalogue of galaxies to trace the evolution of the universe during the last 10,000 million years.
The ALHAMBRA project, led by researchers from the Instituto de Astrofísica de Andalucía, has identified and classified more than half a million galaxies, after seven years of close observation of the universe from the Observatory of Calar Alto (CAHA, Almería) and thanks to a technique that breaks the stars energy in their colours through astronomical filters.
In addition, this research has also allowed calculating the distances from these galaxies to us with unprecedented accuracy. ALHAMBRA (Advanced Large, Homogeneous Area Medium Band Redshift Astronomical survey) has a system of twenty filters covering all wavelengths in the optical and three filters in the infrared, which allows to accurately determine the energy emitted by galaxies and the distance of half a million galaxies with unprecedented depth for the sample size.
