Nearly all of the quantitative information we have about the cosmos is the result of the analysis of spectra. We can directly measure the temperature, density, pressure, or composition of a cloud of gas or a star, using a telescope and a spectrometer. This spectrum forms in highly non-equilibrium gas and dust.
Cloudy is a code that simulates such environments. It calculates the plasma state, chemistral equilibrium, radiation transport, and dynamical problems simultaneously and self consistently, building from the foundation of individual atomic and molecular processes. The code can be applied to a wide variety of spectroscopic and physical problems. The School will cover observation, theory, and application of Cloudy to a wide variety of astronomical environements.
