Upcoming radio telescope sky surveys are set to observe millions of early Universe galaxies. However, to handle this massive influx of data, automatic tools are essential. An algorithm developed by a team from the Institute of Astrophysics and Space Sciences (IA) at the Faculty of Sciences, Universi

Massive stars burn out quickly. When they die, they expel their gas as outflowing winds.

A new class of extragalactic astronomical sources discovered in 2021, named odd radio circles (ORCs)1, are large rings of faint, diffuse radio continuum emission spanning approximately 1 arcminute on the sky. Galaxies at the centres of several ORCs have photometric redshifts of z ≃ 0.3–0.6, implying physical scales of several 100 kpc in diameter for the radio emission, the origin of which is unknown. Here we report spectroscopic data on an ORC including strong...

It’s not always easy to match objects from various telescopic surveys. A new method can change this, allowing objects to be matched in up to 100 different surveys.

Astronomers from Western Sydney University recently discovered something really interesting happening in a black hole in a “nearby” galaxy.

Our galaxy should be full of traces of dead stars. Until now, we have found surprisingly few of these supernova remnants, but a new telescope collaboration is changing that.

Two major astronomy research programs, called EMU and PEGASUS, have joined forces to resolve one of the mysteries of our Milky Way: where are all the supernova remnants? A supernova remnant is an expanding cloud of gas and dust marking the last phase...
