"NEW TYPE OF STAR FORMATION WITNESSED BY ESO'S VERY LARGE TELESCOPE"
New observation from ESO's Vey Large Telescope have shown stars forming in the immense outflows of galaxies, which are fuelled by central supermassive black holes.
Using two VLT's instruments - MUSE and X-shooter, an intentional team of astronomers have been conducting on a stud on an ongoing collision between two galaxies, known collectively as LEDA 70861.
"Astronomers have thought for a while that conditions within these outflows could be right for star formation, but no one has seen it actually happening as it’s a very difficult observation. Our results are exciting because they show unambiguously that stars are being created inside these outflows,” said team leader Roberto Maiolino, professor of experimental astrophysics at the University of Cambridge, UK.
By using X-shooter to rule out possible causes of illumination, the team made the unmistakable detection of an infant stellar population in the outflow. Stars born from the outflow have been observed to be hotter and brighter than stars formed in less extreme environments such as the galactic disc.
“If star formation is really occurring in most galactic outflows, as some theories predict, then this would provide a completely new scenario for our understanding of galaxy evolution,” Prof. Maiolino said.
