WebbGas clouds are cold.”. Kensi: “Emission lines are created in hot sources, like a fluorescent lamp. Absorption lines are made when light passes through a colder source like gas clouds, and the gas absorbs particular wavelengths of light.”. Do you agree with any of these students, and if so, whom?

WebbWe propose to take advantage of a newly-completed Herschel survey of the Galactic plane in both of the [NII] lines at 205 μm and 122 μm wavelength, complementing the GOT C+ survey of [CII]. The relative intensity of the two [NII] lines is a direct indicator of the electron density, and thus allows determination of the N+ column density. Webb23 nov. 2009 · Emission lines are observed almost everywhere in the Universe, from the Earth's atmosphere (see Wyse & Gilmore 1992 for a summary) to the most-distant objects known (quasars and galaxies), on all scales and at all wavelengths, from the radio domain (e.g. Lobanov 2005) to gamma rays (e.g. Diehl et al. 2006). They provide very efficient … WebbPhotographic Astronomik Narrowband-Emissionline filter SII-CCD with 6nm FWHM and MFR Coating.

WebbEmission-Line Measurements Emission-Line Parameters The table below provides a compilation of emission-line parameters gathered through the development of the DAP. Many of them have not actually been fit by the DAP in any survey-level runs of the software and are simply collected here for reference. WebbThere are strong emissions of [OIII] and He II in the core. The colored narrowband image of M27 (NGC6853, PN G060.8-03.6) presented above is unusual because it separates the closely overlapped emission lines of H-a (656.3 nm) and [NII] (658.3 nm) using 3 nm FWHM Astroodon narrowband filters.

WebbH-alpha ( Hα) is a deep-red visible spectral line of the hydrogen atom with a wavelength of 656.28 nm in air and 656.46 nm in vacuum. It is the first spectral line in the Balmer series and is emitted when an electron falls from a hydrogen atom's third- … WebbThis method is used in flame emission spectroscopy, and it was also the method used by Anders Jonas Ångström when he discovered the phenomenon of discrete emission lines in the 1850s. [1] Although the emission lines are caused by a transition between quantized energy states and may at first look very sharp, they do have a finite width, i.e. …

You can get a very narrowband NII filter, but there are only a few objects it's useful on (M1, M27, M97, etc). If you're looking for objects with bright, distinct OIII emission, look to the SNRs.

WebbIn this work a new spectroscopic method, allowing gas temperature determination in argon non-thermal plasmas sustained at atmospheric pressure, is presented. The method is based on the measurements of selected pairs of argon atomic lines (Ar I 603.2 nm/Ar I 549.6 nm, Ar I 603.2 nm/Ar I 522.1 nm, Ar I 549.6 nm/Ar I 522.1 nm).
