Similarly to Lyman-alpha, the K-alpha emission is composed of two spectral lines, K-alpha 1 (Kα 1) and K-alpha 2 (Kα 2). [6] The K-alpha 1 emission is slightly higher in energy (and, thus, has a lower wavelength) than the K-alpha 2 emission. For all elements, the ratio of the intensities of K-alpha 1 and K-alpha 2 is very close to 2:1. [7]

[1] The study teams observed X-ray emissions from the "broad iron K line" near the event horizon of several super-massive black holes of galaxies called MCG-6-30-15 and MCG-5-23-16. The normally narrow K-line is broadened by the doppler shift ( red shift or blue shift ) of the X-ray light emitted by matter being affected by the gravity of the ...
Data for the second quarter was revised lower to show productivity rising at a 2.1% pace instead of the previously reported 2.5% rate. US worker productivity rises moderately in third quarter ...
The early high-energy end of the spectrum for this diffuse X-ray background was obtained by instruments on board Ranger 3 and Ranger 5. [1] The X-ray flux corresponds to a total energy density of about 5 x 10 −4 eV/cm 3. [1] The ROSAT soft X-ray diffuse background (SXRB) image shows the general increase in intensity from the Galactic plane to ...
Sean Ono Lennon has assumed the mantle of managing his family’s singular musical legacy. A deeply moving 11-minute animated short called War Is Over!, earned an Academy Award in March. The ...
The first locally transmitted case of dengue fever in 2024 in Texas has been recorded in Cameron County, the Texas Department of State Health Services says.
[21] [25] Despite the uncertainties in modeling the unusual supernova, it was also used to estimate a very approximate distance of 8.5 ± 1.3 Mly (2.6 ± 0.4 Mpc) to Messier 81. [20] As a local galaxy, the Central Bureau for Astronomical Telegrams (CBAT) tracks novae in M81 along with M31 and M33. [26]
