WITH the continuous spectrum described by Lyman (Astrophysical Jour., 60, 1) as a background, and with hydrogen flowing through the receiver of the spectrograph, it was found possible to ...

IN the Zeitschrift für Physik for August, Kondratjew and Leipunsky describe the emission spectrum of chlorine heated in a silica tube to about 1000° C. I compared their photograph with one taken ...

What makes it so strange are its spectra, which showed a large spike in Lyman-alpha, or the hydrogen emission line. While stars are made of hydrogen – so this might not seem too weird ...

Learn how hot gases and can emit visible line spectra, and how they can absorb wavelengths of light. You’ll also learn about the Big Bang Theory.

What makes it so strange are its spectra, which showed a large spike in Lyman-alpha, or the hydrogen emission line. While stars are made of hydrogen – so this might not seem too weird ...

Atomic Emission Spectroscopy (AES) identifies and quantifies elements by analyzing their unique emission spectra from plasma-induced excited states. Atomic Emission Spectroscopy (AES) ... lines in the ...

Alluxa’s novel H-alpha filters are revolutionizing the ultra-narrow optical filters market. Alluxa, Inc., a global leader in high-performance optical coatings, filters, and thin-film deposition ...

The result also shows that using clean hydrogen in China is expected to save 1.72 trillion US dollars by 2060 in investment costs to achieve carbon neutrality compared with a no-hydrogen scenario.

Using PRIYA, the team studied spectrograms, which are images of hydrogen emission lines in the universe. The spectrograms captured the Lyman-Alpha forest, a dense crowd of absorption lines in ...
