Production of detailed radio images of the Milky Way galaxy shows the existence of supernova images Research teams from Australia and Italy | Oceania Science and Technology News | Oceania Science Portal Communicating the current state of science and technology in Oceania (Australia, New Zealand, etc.)

The Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia announced on January 17 that researchers from Macquarie University in Australia and the National Institute of Astrophysics (INAF) in Italy, using the CSIRO radio telescope, announced that it had produced the largest radio detailed. ever image of a supernova remnant in the Milky Way galaxy.

As part of the PEGASUS and EMU observing projects using two radio telescopes owned and operated by CSIRO, ASKAP and Murriyang, the researchers surveyed a large region of the observed Milky Way galactic plane. This image was published for the first time as a composite image of the data obtained from these surveys.

It is estimated that the Milky Way contains many more supernova remnants than are currently seen, but no telescope has been made sensitive enough to detect them.

“The new image clearly shows an area of ​​the Milky Way that can only be seen with radio telescopes,” said Macquarie University professor Andrew Hopkins, lead scientist on the EMU project. “Although only seven supernova remnants have been discovered, this image reveals more than 20 possible supernova remnants.”

“Eventually, we will have an unprecedented image that is 100 times larger than this one and captures almost the entire Milky Way,” he said.
