Emission Spectra Calculated from Turbulent Mixing Layer Simulations

CLOUDY: Download Input Spectra for CLOUDY

Spectrum averaged over all sight lines (256 sight lines) vertical to x-axis at t = 50 Myr:

   ● Collisional Ionization Equilibrium (CIE) Spectra: CL_P230_Ep0100_CIE.dat

   ● Non-Equilibrium Ionization Spectra of C, N, and O + CIE spectra of other elements:

      CL_P230_Ep0100_NEI.dat

  

Spectrum 1: “Model A” simulation from Kwak and Shelton (2010)

 

Spectrum 2: P/k = 2300 cm^-3 K

(thermal pressure is factor 10 larger than “Model A” Simulation by increasing the density of cool and hot gas by factor 10)

Notes:

1. format of data files: two columns with (x, y)

    x: frequency in Hz          y: flux per Hz (erg cm^-2 s^-1 Hz^-1)

    x is in a range of [1.2x10¹⁵, 7.3x10¹⁵] Hz corresponding to [5, 30] eV

  ** Other ranges of x (with a higher resolution as well) and corresponding y can be

      calculated upon request (contact me at kkwak AT physast.uga.edu for this).

2. In NEI spectra, only line emissions are calculated from NEI populations of carbon,

    nitrogen, and oxygen. Continua and line emissions from elements other than C, N,

    and O are calculated from CIE.

3. STAY TUNED!! More spectra will be calculated and added from different times

   (earlier and later than t=50 Myr). 

These are spectra from turbulent mixing layer simulations (Kwak and Shelton, 2010, accepted to ApJ, preprint available from astro-ph). The spectral files are in the format  that CLOUDY reads, i.e., they have two columns. The first column is frequency in Hz and the second is flux per Hz (erg cm^-2 s^-1 Hz^-1).
