From the Big Bang to Turbulence in Galactic Halos

Thursday Colloquium

#Thursday Colloquium with Yuval Birnboim

The universe began with the Big Bang—an expansion of a mixture of a ‘soup’ of matter and radiation that quickly disperses and cools. The expending matter had minor imperfections, that were amplified by gravity into the first cosmic structures, forming dark-matter halos filled with hot, diffuse gas: the circumgalactic medium. Within these halos, inflowing and outflowing gas interact to produce turbulence that spreads energy and matter around and strongly affects how galaxies grow and evolve.

This #Thursday Colloquium with Yuval Birnboim connects cosmology’s grand narrative with the physics of chaotic motion in galactic halos, highlighting how simulations and philosophy together help us understand complexity, uncertainty, and the surprising order that emerges from cosmic turbulence.
