H-, He-like recombination spectra III: -changing collisions in highly-excited Rydberg states and their impact on the radio, IR and optical recombination lines
F. Guzmán, M. Chatzikos, P. A. M. van Hoof +4
At intermediate to high densities, electron (de-)excitation collisions are the dominant process for populating or depopulating high Rydberg states. In particular, the accurate know…
The [CII] 158 micron line emission in high-redshift galaxies
G. Lagache, M. Cousin, M. Chatzikos
The [CII] fine structure transition at 158 microns is the dominant cooling line of cool interstellar gas, and is the brightest of emission lines from star forming galaxies from FIR…
Thermodynamically-consistent semi-classical -changing rates
R. J. R. Williams, F. Guzmán, N. R. Badnell +3
We compare the results of the semi-classical (SC) and quantum-mechanical (QM) formalisms for angular-momentum changing transitions in Rydberg atom collisions given by Vrinceanu & F…
H, He-like recombination spectra I: -changing collisions for hydrogen
F. Guzmán, N. R. Badnell, R. J. R. Williams +3
Hydrogen and helium emission lines in nebulae form by radiative recombination. This is a simple process which, in principle, can be described to very high precision. Ratios of He I…
Implications of Coronal Line Emission in NGC 4696
M. Chatzikos, R. J. R. Williams, G. J. Ferland +7
We announce a new facility in the spectral code CLOUDY that enables tracking the evolution of a cooling parcel of gas with time. For gas cooling from temperatures relevant to galax…
