York University and an international team of astrophysicists have made an ambitious attempt to simulate the formation of galaxies and cosmic large-scale structure throughout staggeringly large swaths of space.
Using the James Webb Space Telescope (JWST), researchers from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS) team, including York University, have identified the most distant globular clusters ever discovered. These dense groups of millions of stars may be relics that contain the first and oldest stars in the universe.
Galaxies grow large by eating their smaller neighbours, finds an international research team, including York University. Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now through a combination of observation and modelling, researchers, including the Faculty of Science’s Leo Alcorn, a York Science Fellow, have found a clue.
