WebAug 22, 2006 · The H alpha line is flanked by two NII emission lines. Only the very narrow H alpha filters (3nm) can separate Halpha from the NII lines. Therefore most "H alpha" images are actually H alpha + NII images. H beta is an isolated line and allows to record the HII information without interfering other emission lines. #11 jjongmans Vostok 1 Posts: 186 WebAGN Emission Lines - H. Netzer. 11.3. LINERs. LINERs are the least luminous and the most common AGNs. At least 30% of all spirals show this phenomenon and the fraction may even be larger. LINERs show strong, low excitation emission lines, compared with the high excitation narrow lines of other AGNs. Their typical [ OII] 3727 / [ OIII] 5007 line ...

WebJan 7, 2024 · H α emission happens when an electron makes a transition from the third energy level to the second, emitting a photon in the process with the energy equivalent to the difference of the energies of the two states, roughly 1.9 eV. WebA particular emission line of hydrogen is originally emitted with a wavelength of 656.3 nm from a gas cloud. At our telescope, we observe the wavelength of the emission line to be 656.6 nm. How fast is this gas cloud moving toward or away from Earth? Solution meals2people

WebSome spectra show only absorption lines, or absorption lines with very weak hydrogen emission lines. What you should be looking for are absorption lines of ionized calcium, lines designated by "H" and "K" [rest wavelengths of 396.85 and 393.37 nm (3968.5 and 3933.7 Angstroms)] and the emission of the H-alpha line of hydrogen [rest wavelength … meals you can prepare and freeze
