Cosmic rays are subatomic particles that originate in our galaxy or in an extragalaxy. Their sources can be the most violent cosmic bodies, such as a black hole or a supernova. The primary particles of cosmic radiation can be from hydrogen nuclei to iron nuclei, which can reach ultra-high energies of up to 10^20 eV. When such a cosmic particle enters the atmosphere, upon interaction with atoms and molecules in the atmosphere, it disintegrates through an avalanche cascade into a succession of other elementary secondary particles, such as electrons, muons, neutrinos, etc. The atmosphere therefore becomes our natural calorimeter for observing the so-called atmospheric jets, through which primary cosmic rays are detected indirectly from Earth, through various detection techniques, which measure the secondary particles that reach the ground (i.e. ground-based hybrid detectors), which observe on moonless nights the UV radiation produced in the atmosphere by the excitation of nitrogen molecules by the electrons and positrons of the atmospheric jets (i.e. optical telescopes), which record the electromagnetic waves produced by the deflection of electrons and positrons in the Earth's magnetic field (i.e. radio antennas). All these hypostases and detection methods are found in several artistic illustrations made in watercolor, with application to the Pierre Auger Observatory, the largest cosmic radiation experiment in the world, located in the Argentine pampas, near the city of Malarg\u00fce, an area without industrial pollution or other light or sound disturbances, with favorable environmental conditions for indirect measurements of cosmic messengers, using hybrid and complementary detection techniques over an area of \u200b\u200b3000 km^2.<\/p>\n\n\n\nThe artistic approach<\/strong>
In order to create these artistic illustrations, which would highlight the above-mentioned, it was necessary first of all to understand this entire elaborate process, from the generation of cosmic radiation, their path through the Universe and their dispersion in the form of jets in the Earth's atmosphere, then their detection on the ground. During the documentation period, which lasted more than a month, Gina Isar, a specialist in these issues, provided me with articles, graphic representations and technical aspects of the detection equipment, but above all she explained to me in detail and answered all my questions. The actual work followed, which was in itself a new challenge, namely to translate aspects and details that are practically invisible into visual images.
It's paradoxical how the human brain works, how you can, through imagination and creativity, make such a great journey, from a black hole somewhere in the Universe to cross the galaxy to Argentina, to the Pierre Auger Observatory, inside the detection tank and the eye of the telescope, while you are actually at home, in Bucharest...
It remained to transfer everything I visualized in my mind onto watercolor paper. It was fascinating to see how in the film of water on the surface of the sheet of paper, the color left behind by the brush gradually made the black hole, the radiation beam, the stars and celestial bodies in the galaxy appear, then the cascading jet as the radiation entered the Earth's atmosphere, the telescopes' calibration laser, whose eyes detected the signal, the network of detection tanks with pure water and what was happening in them, with the antennas transmitting, and all this in an arid landscape of the Argentinean pampas, at night.
The result was six sequential works measuring 30\u00d740 cm and a final foldable work, which depicts a vertical section measuring 21\u00d7140 cm.<\/p>","protected":false},"excerpt":{"rendered":"Cercetare \u0219i art\u0103 contemporan\u0103 prin pictur\u0103.
