Resonant scattering, metallicity, and redshift (Cloudy scripts)

<p>The warmer gaseous component of the Large Scale Structure of the Universe emits primarily in the X-ray portion of the electromagnetic spectrum, mostly through thermal emission. Resonant scattering of X-ray background radiation by the Warm-Hot Intergalactic Medium (10<sup>5 </sup>K < T < 10<sup>7</sup> K), however, can contribute significantly to the amplitude of the resonant emission lines of selected ions (with an increment of more than a factor 30).</p>

<p>Tables for the emission (thermal and resonant scattering) at different temperature, density, metallicity, and redshift are generated with Cloudy. The comparison between thermal emission and resonant scattering contributions is performed with Jupyter Notebooks.</p>

<p>All the material related to the published paper is stored in four sets: “Cloudy scripts”, “Jupyter scripts”, “Data”, and “Figures”. Additional material, that extends beyond the initial investigation, will be stored at a later time (the description will be updated accordingly).</p>

<p>Cloudy Scripts.</p>

<p>The Cloudy script “runcloudy” is the basic script to launch cloudy activities.</p>

<p>The Cloudy script “runbatchcloudy” is called by “runcloudy” and runs all simulations.</p>

<p>The Cloudy scripts “*.in” are called by runbatchcloudy and contain the instructions for each simulation. Input files ending with the tags "01HM", "02HM", "05HM", "HM12", and "KS19" are used to compare the different CXB models.</p>

<p>The output is very large, each simulation generating about 30 GB of data (not included in this repository). One simulation runs in about 1 hour.</p>
