This new type of gamma-ray source is produced by electrons and positrons diffusing out of the pulsar wind nebula and scattering ambient photon fields to produce gamma rays. This correspondingly new field of study comes with a number of observations and constraints at different wavelengths and a ...
Millisecond pulsars (MSPs) also emit gamma-ray pulsations, as revealed by the Large Area Telescope (LAT)15onboard the Fermi Gamma-ray Space Telescope. Gamma rays are particularly helpful in discovering and studying spider pulsars because, unlike radio waves, they are not absorbed in the diffuse ...
However, in addition to the classic pathological examination of excision tissues, the selection of a surgical plan largely relies on surgeons’ experience. In terms of imaging, different diagnostic algorithms using dermoscopic findings have been developed for melanoma. Pattern analysis, which provides an...
we selected JADES galaxies with a confident spectroscopic redshift above z > 4 with a median signal-to-noise ratio of at least 3 per spectral pixel in the region corresponding to rest-frame wavelengths of 1,268 Å < λemit < 2,580 Å. ...
Of the following, which is not electromagnetic in nature? (a) microwaves (b) gamma rays (c) sound waves (d) radio waves (e) all of the above (f) none of the above Waves: Waves are a periodic spatial or...
This testing was performed to explore various Raman measurement configurations for analyzing lunar regolith, especially in terms of capturing distinctive fluorescence features that can provide more information about the composition of the regolith. Results obtained utilizing configurations having a 785 nm ...
Alternatively, the absorption spectra of an eluted substances could be obtained for identification purposes by scanning over a range of wavelengths. The latter procedure, however, differs with the type of multichannel detector being used. There are two basic types of multi–wavelength detector, the...
Better understanding of the IR-RIA remains of primary importance as most of the data links and point or distributed sensing technologies are operating in this range of wavelengths in order to benefit from the low intrinsic fiber attenuation and all the knowledge and tools gained through the ...
results indicate that photons carrying orbital angular momentum should be created naturally by cyclotron/synchrotron radiations or Compton scatterings in various situations in cosmic space. We propose promising laboratory vortex photon sources in various wavelengths ranging from radio wave to gamma-rays. ...
However, at very high intensities or at shorter wavelengths the photon’s linear momentum has been shown to become essential for an accurate description of the electron emission. The momentum transfer can lead to a symmetry breakdown in terms of a forward-backward asymmetry in the photoelectron ...
