International team discovers major supercluster of galaxies hidden by Milky Way

A team of South African and international collaborators uncovered a previously unknown, major supercluster in the constellation Vela. The Vela supercluster might have a significant influence on the motion of our Local Group of galaxies (which includes the Milky Way) and could help resolve some riddles of the observed flows of galaxies around us. The team, led by Prof Renée C Kraan-Korteweg (UCT), includes Dr Michelle Cluver (UWC), Dr Maciek Bilicki (Leiden, former UCT PDRF), SARChI Chair Prof Thomas Jarrett (UCT), next to colleagues from the RSSA (ANU) and the MPGE, Munich.

UCT astronomer part of international team that discovers a giant stellar void in the Milky Way Galaxy

A major revision is required in our understanding of the Milky Way Galaxy, according to an international team of astronomers led by Professor Noriyuki Matsunaga of the University of Tokyo. This is after a team of astronomers, which included Professor Michael Feast of the University of Cape Town, found that there was a huge region around the centre of our own Galaxy which was devoid of young stars.

Breakthrough for astronomers from UCT and the Southern African Large Telescope (SALT)

A team of astronomers has identified a rare star that exploded around 1,500 years ago. At the time, the star would have outshone all the stars of the Orion constellation, reaching a similar brightness to Jupiter in the night sky.

An international team of scientists that includes a leading astronomy researcher from the University of Cape Town and one from the South African Astronomical Observatory (SAAO) have helped to make a groundbreaking discovery by peering through the stars and dust of the Milky Way with a radio telescope to discover hidden galaxies beyond. Both are available for interview. The study involved researchers from Australia, South Africa, the USA and the Netherlands.

Pathfinders HI Science Coordination Committee (PHISCC) 2016

The 2016 meeting of the Pathfinders HI Science Coordination Committee (PHISCC), was held in Cape Town, South Africa, from 1-3 February 2016.
For PHISCC 2016 the aim was to bring together the people designing specific tools for the upcoming large HI surveys with the astronomers that are going to use them.
