Supercomputer creates gorgeous picture of supernova remnant


Australia’s latest supercomputer has crunched lots of knowledge to create a shocking picture of a supernova remnant.

The supercomputer — named Setonix after Western Australia’s favourite animal, the quokka (Setonix brachyurus) — created the extremely detailed picture utilizing knowledge collected by ASKAP (Australian Sq. Kilometre Array) radio telescope, which is operated by CSIRO (Commonwealth Scientific and Industrial Analysis Organisation), the nation’s science company.

Setonix is positioned on the Pawsey Supercomputing Analysis Centre in Perth and is a key a part of the power’s current $70 million improve. The supercomputer is being put in in two levels, with the second stage anticipated to be up and operating by the tip of 2022.

Dr Pascal Elahi, Pawsey’s supercomputing functions specialist, mentioned that processing knowledge from ASKAP’s astronomy surveys “is a good way to stress-test the Setonix system and see what is feasible.”

This radio continuum (943.5 MHz) ASKAP picture is of the galactic supernova remnant G261.9+5.5, positioned someplace between 10,000 and 15,000 mild years away. It was initially found by CSIRO scientist E. R. Hill in 1967, nonetheless not a lot is thought about it. The morphology of the remnant revealed within the ASKAP picture will assist finding out the remnant and its surrounding medium in unprecedented element. Researchers hope to retrieve extra details about the remnant’s age, dimension and sort from this knowledge. Credit score: Dr Wasim Raja/CSIRO, Dr Pascal Elah/Pawsey

Dr Wasim Raja, a researcher on CSIRO’s ASKAP workforce, mentioned the challenges in imaging a fancy object like a supernova remnant (primarily the clouds of fabric that emerge from the explosion of an enormous star on the finish of its life) made it the perfect dataset for testing Setonix’s processing software program.

“Setonix’s massive, shared reminiscence will permit us to make use of extra of our software program options and additional improve the standard of our pictures,” Raja mentioned. “This implies we will unearth extra from the ASKAP knowledge.”

When the second stage of Setonix is absolutely deployed, the supercomputer will probably be as much as 30 instances extra highly effective than the mixed functionality of Pawsey’s earlier methods, Galaxy and Magnus.

The elevated processing energy signifies that we are able to anticipate much more unimaginable pictures from Setonix as ASKAP plans to ship it extra knowledge from bigger and deeper surveys of the sky.
