Mapping the cosmic web with fast radio bursts

21 November 2016 Astronomy Now

Fast radio bursts, or FRBs, are mysterious flashes of radio waves originating outside our Milky Way galaxy. A team of scientists, jointly led by Caltech postdoctoral scholar Vikram Ravi and Curtin University research fellow Ryan Shannon, has now observed the most luminous FRB to date, called FRB 150807.

‘Birthplace’ of a fast radio burst located for the first time

25 February 2016 Astronomy Now

An international team of scientists led by a Square Kilometre Array (SKA) project scientist has for the first time managed to identify the location of a fast radio burst using a combination of radio and optical telescopes, allowing them to confirm the current cosmological model of the distribution of matter in the universe.

Noodle-shaped plasma lenses may lurk in the Milky Way

22 January 2016 Astronomy Now

According to a team of astronomers led by Dr. Keith Bannister of CSIRO Astronomy and Space Science Division in Australia, invisible noodle- or shell-shaped plasma structures could be floating around in the Milky Way. These structures, which focus and defocus radio waves from distant sources such as quasars, could radically change our ideas about the Galaxy’s interstellar gas.
