| Abstract: I’ll try to sketch an intuitive feedback picture that runs from the star-forming interstellar medium to the circumgalactic medium. In the disk, supernovae drive turbulence and help regulate star formation by balancing the vertical weight of the gas. But when hot supernova remnants or "superbubbles" reach the disk scale height before catastrophic cooling, feedback changes character: it breaks out, vents hot gas into the halo, and turns a local interstellar medium problem into a galaxy–halo circulation problem. I’ll use that transition to connect star-formation self-regulation, outflows, and the origin of multiphase circumgalactic gas, with some discussion of down-the-barrel and quasar-absorption constraints, turbulent radiative mixing layers, and why the geometry of phase interfaces may matter as much as the launch physics. | |
