| Abstract: | Sometimes the most beautiful things are the hardest to understand. Pillars like those of the Eagle Nebula form at the boundary
between some of the hottest (10000~K) and coldest (10~K) gas in the Galaxy. Many physical processes come into play in the
birth and growth of such gaseous pillars: hydrodynamic instability, photoionization, ablation, recombination, molecular heating
and cooling, and probably magnetic fields. High-quality astronomical observations, quantitative numerical simulations, and
scaled laser experiments provide a powerful combination for understanding their formation and evolution.
We put our most recent hydrodynamic model to the test, by creating simulated observations from it and comparing them directly
to the actual radioastronomical observations. Successfully reproducing major characteristics of the observations in this manner
is an important step in designing appropriate laser experiments. |
