Taking advantage of strong gravitational lensing, we have recorded the rest-frame ultraviolet (UV) spectrum of the z= 2.38115 galaxy ‘the Cosmic Horseshoe’ (J1148+1930) at higher resolution and signal-to-noise ratio than is currently feasible for unlensed galaxies at z= 2–3. With a star...
It's an infrared shot which means only the infrared light is let through while the ultraviolet spectrum is blocked. Spooky feeling in storm clouds; PICTURE of the week Jennifer Johnson, an associate professor of astronomy at Ohio State University, says tellurium has been a "tough" element to ...
Machine learned interatomic interaction potentials have enabled efficient and accurate molecular simulations of closed systems. However, external fields, which can greatly change the chemical structure and/or reactivity, have been seldom included in curr
An ultraviolet absorption spectrum of SO2 ice deposited at 9 K was recorded over the wavelength range 240–320 nm (Fig. 2). The spectrum of this unirradiated ice exhibits a peak at 281 nm, characteristic of solid SO2 (Holtom et al., 2006; Mason et al., 2006). After irradiation using...
Ultraviolet spectrum and decay of the ozonide ion radical, Oââ», in strong alkaline solution. [Electron beams] Pulse radiolytic experiments in strong alkaline solution (pH 13-14) on the formation and the decay of the ozonide ion radical, O, are reported. The high-pr... K Sehest...
Since this star has a peak wavelength that is at a shorter wavelength (in the ultraviolet part of the spectrum) than that of our Sun (in the visible part of the spectrum), it should come as no surprise that its surface temperature is much hotter than our Sun’s. We can also describe...
The extreme ultraviolet spectrum of the sun: Detwiler, C. R., J. D. Purcell, and R. Tousey, U. S. Naval Research Laboratory, Mémoires Soc. R. Sc. Liège, 1960, 17 pp., Illus.doi:10.1016/0038-092X(65)90195-7ELSEVIERSolar Energy...
In fact, while each of these collective charge oscillation modes lies in the ultraviolet-frequency region, the integral over plasmonic frequency shifts is situated in the infrared range. The coupling between quick many-electron oscillations and slow collective atomic vibrations is thus an essential ...

Ultraviolet rays can be divided into four regions according to different wavelengths: uva for short, with the wavelength of 320nm ~ 400nm; Ultraviolet B (UVB) is short for UVB, the wavelength is 280 nm ~ 320 nm; Short wave ultraviolet (UVC) is short for UVC, the wavelength is 200 nm...
