Feeding a baby star through a whirlpool in space

An international research team, led by Chin-Fei Lee at Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has detected a pair of spiral arms in an accretion disk around a protostar (baby star), using the Atacama Large Millimeter/ submillimeter Array (ALMA). Interestingly, these spiral density enhancements make the disk appear like a “space whirlpool.” … Read more

Massive filaments fuel the growth of galaxies and supermassive black holes

An international group of scientists led by the RIKEN Cluster for Pioneering Research have used observations from the Multi Unit Spectroscopic Explorer (MUSE) at the ESO Very Large Telescope (VLT) in Chile and the Suprime-Cam at the Subaru telescope to make detailed observations of the filaments of gas connecting galaxies in a large, distant proto-cluster … Read more
