Further astronomical work in the infrared

For radio-emitting sources, IR data fits well into the linear interpolation between the visible region and the radio range. For radio quasars, a similar line connecting these two regions of the spectrum should have a steeper slope, since the infrared radiation flux decreases faster with increasing wavelength. Measurements of radio-quiet sources cannot be “fitted” to such a line - there is excess radiation at a wavelength of 100 microns.

Any explanation of these results is still preliminary, but there is the possibility that excess radiation at a wavelength of 100 μm is directly related to the nature of the energy source of the quasars.

It is believed that the main radiation of quasars is synchrotron; it is generated by high-energy electrons that make a spiral motion in magnetic fields. The main source of such electrons may be emissions of matter from the nucleus. The absence of any gaps in the spectrum of radio-emitting quasars suggests that all the received radiation is due to this mechanism. Excess IR radiation from radio quasars may have a different origin; for example, it may be due to thermal emission of dust in the galaxy surrounding the core. Therefore, it can be assumed that radio-quasars may contain more dust than radio-emitting quasars. Dust may be responsible for differences in radio luminosity, as it destroys electron beams.

Although the observations from the IRAS satellite ended a year ago, the project has not yet been completed. The publication of the catalog of point sources and atlases of extended radiation this month will make the data widely available to astronomers. Their analysis and interpretation will continue for several more years. Most of the information received by the IRAS satellite is recorded on magnetic tapes that store data that is unknown to even the most dedicated to the project. The tapes will remain as a reference archive for astronomers - like photographic plates for optical viewing.

The main function of a full astronomical survey is the discovery of new physical phenomena or objects awaiting a more detailed study in this range or in the entire electromagnetic spectrum.

Further work outside the infrared region and some infrared observations can be carried out from the Earth or on airplane telescopes, and the first such studies are already underway. However, for the most interesting sources, long-wave infrared measurements will have to be carried out in space.

For such observations, two instruments were designed in the 90s. The European Space Agency (ISA) will launch an infrared space observatory, and NASA will launch a space infrared telescope laboratory on an orbital plane. These devices will have higher spatial and spectral resolution and sensitivity than the IRAS satellite. If both projects are also successfully completed, like the flight of a pioneering satellite, infrared astronomy will have truly brilliant possibilities. Play Pin Up Casino online.
