It is shown that the features of the detection of simultaneous photon pairs make it possible to visualize a macroscopic object in scattered γ-rays.doi:10.1023/A:1025165628288V. E. Rad'koInstitute of Theoretical and Experimental Physics, Bol'shaya Cheremushkinskaya...
The material in the jet can produce particle/antiparticle pairs that may produce very high energy X-rays and gamma rays. Such an object may be detectable as an X-ray pulsar if the beam is suitably aligned toward the earth. X-ray emission can also be produced by inverse comptonization of...
Using significant correlations between different bands, we aim to identify the best TeV BL Lac candidates that can be discovered by the current and next generation of imaging air...关键词: gamma rays: galaxies DOI: 10.1051/0004-6361/201732550 ...
a, SED combining gamma-ray (diamonds), X-ray (circles) and UVOIR (squares) data at different times, as indicated by the labels. It shows that non-thermal radiation (solid line) dominates at early times and at higher energies. At lower energies, we identify the emergence of a thermal co...
A Am 200 mCi source was used, which emits 59.6 monoenergetic gamma-rays, and the coherent and Compton photons, scattered at an angle of about 150were detected, together with the Ag Xsub(K)-rays. The advantage of the photon scattering technique is that a half-thickness is involved in the...
While occasionally treated as a telltale sign that the solutions are non-physical, NEC violation actually implies that these metrics describe objects which may form in finite time according to distant observers. For reference we summarise here some properties of their EMTs....
billion tons.That's as much as a mountain, notesNASA. Now, scientists using the agency's Fermi Gamma-ray Space Telescope have announced the discovery of nearly 300 unique neutron stars, called pulsars. These are rapidly spinning neutron stars that emit powerful beams of light from their poles...
Recently, the subject has rapidly advanced with the development of observing techniques made possible by the invention of new detectors and telescopes over the entire electromagnetic spectrum from gamma rays to meter-wavelength radio emission. Superbly quantitative measurements of distant planets, satellites...
An object that is translucent is made of a material that is partly transparent, which means you can see through it but not clearly. An example of a translucent material is frosted glass, which is not clear but has a frosty appearance. It is possible to see an object on the other side ...
The purpose of this catalogue is to compile the BL Lac multi-frequency data that is acquired with the RATAN-600 simultaneously at several frequencies. The BL Lac objects emit a strongly variable and polarized non-thermal radiation across the entire electromagnetic spectrum from radio to gamma-rays...
