Platform Game: Physics and Data Management,ming from a photoionizing source, be it a star, a nucleus of an active galaxy, or whatever. Such photoionization-dominated plasmas are very commonly observed in galaxies and historically, were one of the first to be studied in detail, thanks to their bright and prominent emission line spectra at opt

Controlling a Player Character,l bulge of faint Galactic stars is crossed by dark lanes, filaments, and clouds of dense dusty gas made visible in projection. Because the dust grains are very small, typically less than a micron in diameter, their absorption characteristics are very wavelength dependent, and blue or ultraviolet pho

Platform Game: Physics and Data Management, crisscrossed by violent shocks and pervaded by intense UV and X-ray radiation fields, which can easily tear apart delicate molecular bonds. Even the composition of the interstellar medium presents a problem to the formation of complex molecules, since the gas is mostly hydrogen and helium. Reactive

The spatial structure of these various thermal phases is driven by the interstellar gas seeking to
