DESCRIPTION:How do galaxies form? New insights from the FIRE and the role o
 f the circumgalactic medium\n&nbsp\;\nClaude-André Faucher-Giguère&nbsp\;
 \nNorthwestern University\n&nbsp\;\n\nAbstract: Galaxies are remarkably di
 verse in their properties\, ranging from irregular to disky to elliptical 
 in morphology\, and from blue to red in color. At the same time\, when ana
 lyzed systematically\, galaxy populations exhibit striking regularities\, 
 with clear trends with mass and redshift. How does this 'regular complexit
 y' emerge from the hot Big Bang? I will present results from the FIRE simu
 lations which shed some light onto the processes that shape galaxies. The 
 FIRE zoom-in simulations resolve the multiphase interstellar medium of gal
 axies and model several different feedback processes (including Type II/Ia
  supernovae\, stellar winds\, and radiation) while including the cosmologi
 cal environment. I will highlight recent results on the formation of disk 
 galaxies\, the 'burstiness' of star formation\, and galactic winds. Our ne
 w results indicate that transitions in each of these important phenomena c
 an be simultaneously explained by a phase transition in the inner circumga
 lactic medium\, 'inner CGM virialization' (ICV)\, and arise from the inter
 play between feedback energy produced on small scales and the physics of h
 alo gas on larger scales. https://astronomia.uc.cl/2jucext1/institutoastro
