Using the Surface Brightness Fluctuation technique (SBF), IAC researchers have succeeded in detecting galaxies beyond Hubble's photometric detection limit. These new detections are fundamental for obtaining accurate information about the number of weak galaxies. This number is vital for Cosmology and for the theory of galaxy formation and evolution.
This section includes scientific and technological news from the IAC and its Observatories, as well as press releases on scientific and technological results, astronomical events, educational projects, outreach activities and institutional events.

Tests have been carried out for the first time on the hypothesis that the structure of interstellar dust around galactic bars is determined by the velocity field of the gas. The dust is found in regions delineated by high gas speed gradients, something which had been proposed but not observed. The gradients themselves seem to be related to intense star-forming regions.
