SPT2349−56 is one of the most active star-forming complexes known. More than 10,000 stars are born there
Scientists recently completed in-depth observationssupercluster SPT2349−56 in the optical and infrared ranges. The goal is to study stellar masses using spectral energy distribution (SED) analysis. They used the Gemini and Hubble space telescopes to measure the flux in the optical and near-infrared, as well as the Spitzer IRAC camera.
It turned out that the stellar mass in the clusterBy comparison, its star formation rate is close to the value measured in nearby “normal” galaxies. Thus, scientists came to the conclusion that the current star formation processes are similar to the processes in both the early and local Universe. However, there is a deficiency of molecular gas in the cluster. This means that star formation in the supercluster will soon end.
Scientists have discovered the supercluster SPT2349−56 insubmillimeter range with the South Pole Telescope. It is so far away that light from it has been traveling for more than 12 billion years. It contains more than 30 galaxies with submillimeter brightness and dozens of other bright and/or spectroscopically confirmed galaxies with active star formation.
