(ORDO NEWS) — Physicists failed to confirm the hypothesis of the appearance of neutrino and antineutrino beams due to the merging of black holes. To do this, leading minds compared the data of the VIRGO and LIGO gravitational-wave observatories, as well as a special KamLAND particle detector.
The general theory of relativity says that the interaction of any objects with nonzero mass generates gravitational waves – spatial oscillations in time, propagating with light speed. For the first time, experts registered the phenomenon in 2015 with the help of LIGO. Subsequently, the VIRGO device transmits the arXiv portal to search for these distortions.
The KamLAND neutrino detector is assembled from a variety of photosensors and a giant container filled with 1,000 tons of liquid. It is composed of mineral oils, benzene and fluorescent substances. In the center of this large vessel is another vat, into which liquefied xenon-136 was pumped. It is the longest-lived unstable isotope, with a half-life several trillion times the age of the universe. Physicists track antineutrino fluxes, fixing flashes of light that occur when particles collide with protons. KamLAND is the largest and most sensitive low energy neutrino detector in the world.
Our Milky Way galaxy is twisted and deformed by the gravity of its satellite galaxy, the Large Magellanic Cloud. This is the conclusion reached by astrophysicists. Previously, it was believed that the star system in which we are located is static. But scientists at the University of Edinburgh Michael Petersen and Jorge Penarrubia found that 700 million years ago it collided with the Large Magellanic Cloud (LMC) galaxy and since then they have both been under the influence of each other. LMC gravity at a speed of 32 kilometers per second, or 115,200 kilometers per hour, twists the spiral disk of our Galaxy.
As NEWS.ru wrote, astronomers have discovered in the constellation Virgo the BOSS-EUVLG1 galaxy with a “sleeping” supermassive black hole. The galaxy itself emits record-breaking ultraviolet radiation. This is due to the fact that active processes of the formation of new stars are taking place in it.
