Dear Juan, The expansion of the heavy element network is fairly new, and therefore not a lot of people are aware that Cloudy has been expanded to model...
... Hi there, yes, the simulation is designed to be complete. Electron collisional excitation, both thermal and non-thermal, are included, along with pumping...
Hi Nick, I was looking for a documentation about the physics/chemestry implemented in Cloudy for the CN molecule, but I haven't found it. I'm interested in to...
Hi Juan, Cloudy does not calculate level populations of CN, we only calculate the density of CN. The rate coefficients for the reaction network largely come ...
Hello! Does anyone know about any publication regarding measurements and modelling (with cloudy) of the line HeI 1.083 micron in the context of AGNs/Seyfert...
Hi, Cristina. I was unable to find any such papers after some searching on the ADS, but I did find this 1978 paper by Feldman and MacAlpine entitled “A...
Dear Gary, Korista & Goad (2000) make use of the LOC model to interpret the BLR emission of ngc5548. In their fitting grid, they choose to limit the density to...
