Rosetta Mission: Electron Scattering Cross Sections—Data Needs and Coverage in BEAMDB Database
Mason, Nigel J.; Jevremović, Darko; Bredehöft, Jan Hendrik +2 more
The emission of [O I] lines in the coma of Comet 67P/Churyumov-Gerasimenko during the Rosetta mission have been explained by electron impact dissociation of water rather than the process of photodissociation. This is the direct evidence for the role of electron induced processing has been seen on such a body. Analysis of other emission features is…
Models of Emission-Line Profiles and Spectral Energy Distributions to Characterize the Multi-Frequency Properties of Active Galactic Nuclei
La Mura, Giovanni; Berton, Marco; Chen, Sina +7 more
The spectra of active galactic nuclei (AGNs) are often characterized by a wealth of emission lines with different profiles and intensity ratios that lead to a complicated classification. Their electromagnetic radiation spans more than 10 orders of magnitude in frequency. In spite of the differences between various classes, the origin of their acti…
