High-resolution imaging has shown H alpha and infrared structures arising in an ionized flow that partly fills the ring's interior. To constrain the influence of the stellar wind on this structure, we obtained an ultraviolet (UV) spectrum of the central star of SBW1 with the Hubble Space ...
A novel version of spectral phase interferometry for direct electric field reconstruction (SPIDER) based on parametric downconversion is demonstrated. This process is used to completely characterize low-energy, ultrashort optical pulses in the near-ultraviolet region of the spectrumdoi:10.1080/...
Update to the UV-Visible ChemStation method for testing photometric accuracy in the ultraviolet region of the spectrum Technical Note Introduction The photometric accuracy of a spectrophotometer is essential for ensuring correct results. The accuracy of a UV-Vis spectrophotometer is confirmed for the ...
Anything above 400nm is part of the visible light spectrum, so why are these described as “ULTRAVIOLET”? Chris ON 15 Feb, 2022 READ ALL 1 ANSWERS | BEST ANSWER: The LEDs peak wavelengths may be above 400nm but they still output ultraviolet wavelengths in the UV-A region. LEDSupply...
Our results suggest that often-neglected sources of energetic radiation such as stripped binary products and very massive O-stars produce a sharper change in the ionizing spectrum with decreasing metallicity than expected. Consequently, nebular emission in C IV and He II powered by these stars may ...
The ultraviolet photoelectron spectrum of the H2S dimer shows four features with vertical ionization energies of 9.75, 10.95, 12.37 and 13.69 eV; the adiabatic ionization energies of the first two ionic states are 9.56 and 10.75 eV. Molecular-orbital calculations reveal that the first two features ...
Virus formulations were applied to plants that were then exposed to artificial lighting that included wavelengths in the UV range of the spectrum (see below). Two plant species were used: tomato (variety Ailsa Craig) and cabbage (variety Greyhound). These were grown from seed (Moles Seeds, Col...
A initiates melanoma in the HGF mouse model through an oxidative process is consistent with the reported effectiveness of the anti-oxidant N-acetyl cysteine in decreasing melanoma in HGF transgenic mice irradiated with a broadband ultraviolet sunlamp with an emission spectrum similar to that in Fig....
The early version of the ICAM was used previously to measure the absorption spectrum of pure water over the 380-700 nm range. To extend its range into the ultraviolet, several modifications have been completed. The preliminary tests showed that the modified ICAM was able to measure the ...
