STOP! Take 1 minute to watch this amazing visualisation! Visualising the origin of stars in 3D

Project Leader: Dr Amit Seta and Prof Christoph Federrath and Sajay Sunny Mathew

Sajay Sunny Mathew is a PhD student at The Australian National University, working with Dr Amit Seta and Prof Christoph Federrath. Sajay studies star formation through numerical simulations using high-performance computing. He visualises the star cluster formation simulations from Mathew & Federrath (2021) and Mathew, Federrath & Seta (2023), a true challenge due to the process being highly dynamic and chaotic.

Stars come to life in the cold expanse of space within the dense molecular clouds of the interstellar medium. They emerge from the intricate weave of gravity, turbulence, magnetic fields, and echoes of stellar feedback. Turbulence sweeps through the cosmos, shaping the clouds and the fabric of magnetic fields. Essential Forces in Star Formation:

  • Stellar Heating
  • Jets & Outflows
  • Turbulence
  • Magnetic Fields

Normal 2D projections are inadequate to explain the complex structure of star-forming clouds. Therefore, Sajay designed the visualisation in 3D to be viewed immersively, using over 30 million compute hours and 200 terabytes of data at Pawsey Supercomputing Research Centre and National Computational Infrastructure (NCI) for running the simulations and creating the visualisations.

This video was presented at the recent Pawsey Visualisation Conference in July and you can find more of Sajay’s visualisations here: https://bit.ly/3MBiRiO
