Too much heavy metal stops stars producing

Stars evolve according to the elements they manufacture

Stars are giant factories that produce most of the elements in the Universe – including the elements in us, and in the Earth’s metal deposits. But what stars produce changes over time.

Two new papers published in MNRAS shed light on how the youngest generation of stars will eventually stop contributing metals back to the universe.

The authors are all members of ASTRO 3D, the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions. They are based at Monash University, the Australian National University (ANU), and the Space Telescope Science Institute.

Closing in on the first light in the Universe

Research using new antennas in the Australian hinterland has reduced background noise and brought us closer to finding a 13-billion-year-old signal

The early Universe was dark, filled with a hot soup of opaque particles. These condensed to form neutral hydrogen which coalesced to form the first stars in what astronomers call the Epoch of Reionisation (EoR).

“Finding the weak signal of this first light will help us understand how the early stars and galaxies formed,” says Dr Christene Lynch from ASTRO 3D, the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions.

Dr Lynch is first author on a paper published in Publications of the Astronomical Society of Australia. She and her colleagues from Curtin University and the International Centre for Radio Astronomy Research have reduced the background noise in their observations allowing them to home in on the elusive signal.

Saving lives after stroke with a small aircraft or ambulance-mounted CT brain scanner

Adelaide company Micro-X (MX1) has started developing a small CT brain scanner that can be fitted in ambulances and emergency aircraft. If successful, the device will allow paramedics and retrieval teams to diagnose and then start treating stroke patients in the golden hour – the first hour after a stroke.

Rethinking eating disorders from the inside out

Australia’s first national research and translation strategy for a mental health disorder

Online launch 10:15 am AEST, Tuesday 21 September 2021: media welcome, https://www.streamgate.co/insideout-institute/

At least a million Australians affected by eating disorders, but only about 200,000 receive evidence-based treatment

  • Leading psychiatric cause of death
  • Anorexia Nervosa, Binge Eating Disorder, Bulimia Nervosa and other eating disorders are having a profound impact on individuals, families and communities
  • National research strategy launched today says we can improve early identification and treatments and even prevent eating disorders
  • The strategy outlines the ten questions that need answers for us to improve the quality of life for all affected Australians and their families.

Galaxies pump out contaminated exhausts

Corrected 31 August: ‘500 light years’ updated to ‘500 million light years’

Research reveals how star-making pollutes the cosmos

Animation available, astronomers available in Australia and UK for interview

Galaxies pollute the environment they exist in, researchers have found.

A team of astronomers led by Alex Cameron and Deanne Fisher from the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) used a new imaging system on at the WM Keck Observatory in Hawaii to confirm that what flows into a galaxy is a lot cleaner than what flows out.

The research is published today in The Astrophysical Journal.
