Multiphase gas in the baryon cycle: from jellyfish galaxies to turbulent galactic outflows
The formation and evolution of galaxies are shaped not only by gravity but also by the complex behaviour of gas—the dominant baryonic component within and around galaxies. This gas spans a wide range of temperatures, ... -
Multiple Stable States and Abrupt Transitions in Spatial Ecosystems
Ecosystems can exhibit multiple stable states at similar external conditions. Such systems shift from one stable state to another abruptly and discontinuously, when they cross certain threshold parameters. Some examples ... -
