An international team of astronomers, including scientists from the Nicolaus Copernicus University in Toruń, has published the most accurate map of the Universe within low radio frequencies, using the European network of LOFAR receivers.

The researchers looked at the same areas of the sky over and over again and then combined them into a single image with a very long exposure. As a result, faint radio afterglows from stars that exploded as supernovae in tens of thousands of galaxies were detected.

The research was published in a special edition of the scientific journal “Astronomy and Astrophysics”. The authors include Polish astronomers: Prof. Krzysztof Chyży, Dr Arti Goyal, Dr Marek Jamrozy and Dr Błażej Nikiel-Wroczyński from the Jagiellonian University in Krakow; Dr Magdalena Kunert-Bajraszewska and Aleksandra Wołowska from the Nicolaus Copernicus University in Toruń and Dr Katarzyna Małek from the National Center for Nuclear Research.
