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.<\/p>\n\n\n\n<p>This #Thursday Colloquium with Yuval Birnboim connects cosmology\u2019s 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.<\/p>\n\n\n\n<p><sup>This event is addressed to HIAS Fellows and their Tandem Partners.<\/sup><\/p>\n\n\n\n<div class=\"wp-block-group alignwide Pattern-Image-Credits Accordion Accordion--accordionList Accordion--imageCredits has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group alignwide Accordion__list is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-group Accordion__item has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group is-content-justification-space-between is-nowrap is-layout-flex wp-container-core-group-is-layout-cb46ffcb wp-block-group-is-layout-flex\">\n<h3 class=\"wp-block-heading Accordion__title has-xlarge-font-size\">Image Information<\/h3>\n<\/div>\n\n\n\n<div class=\"wp-block-group Accordion__wrapper has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<div class=\"wp-block-group Accordion__content has-global-padding is-layout-constrained wp-block-group-is-layout-constrained\">\n<p>A galaxy group 6.5Gyr after the big bang.
