Sentences with phrase «frequency spectral line»

Graduate student Jialu Li, in collaboration with the Argus instrument team and DEGAS project, made these images (the highest frequency spectral line observations the Green Bank Telescope has ever made) in only 10 hours on 2017 October 25 and 26.

I understand (to some extent) how individual atoms can radiate specific frequency spectral lines, as a result of energy level transitions of an electron in that atom.

Not exact matches

Yet so far, star formation historians have mostly relied on other indicators to write their histories: light at a particular frequency that is typically emitted when giant clouds collapse, heating up in the process and radiating away that heat in the form of specific spectral lines.

With spectral data taken in a wide frequency range, we can obtain intensity ratio of various molecular line emissions.

A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.

We characterize the main emission lines found in the spectrum, which primarily arise from a range of components associated with Orion KL including the hot core, but... ▽ More We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (band 6b) and 1788.4 - 1906.8 GHz (band 7b) obtained using the HIFI instrument on board the Herschel Space Observatory.

Note however that all the radiation in a spectral line is not at exactly a single frequency, but instead in a small range (band) of frequencies.
