Black hole model reveals star collapse without bright explosion

A team of scientists, including Chief Investigator Ilya Mandel from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) at Monash University, recently studied what happens to rotating massive stars when ...

How galaxies and black holes grow together

Over the past two decades, astronomers have concluded that most, if not all, galaxies host massive black holes at their centers—and the masses of a black hole and its host galaxy are correlated. But how are the two connected? ...

South Africa's MeerKAT solves mystery of 'X-galaxies'

Many galaxies far more active than the Milky Way have enormous twin jets of radio waves extending far into intergalactic space. Normally these go in opposite directions, coming from a massive black hole at the centre of the ...

Astrophysicists wear 3-D glasses to watch quasars

A team of researchers from Russia and Greece reports a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3-D image by feeding each ...
