Why Is Fusion Of Neutron Stars Generates Gravitational Waves And A Celestial Light Show Considered Underrated?

Hello everyone, welcome to my blog post today we will be looking at gravitational waves. more than if not 70 observatories or scientist studied this for years.

Four times in the past two years, physicists working with giant gravity waves detect that they are pushing at night, sending invisible waves through space-time. He announces the discovery of the fifth disturbance of this species, but this time astronomers saw every wavelength of the light gamma ray. As physicists have foreseen the unprecedented view of cosmic cataclysm - to which the two stars have merged the superdense neutrons - each has the same idea of horns, each of which represents a scientific breakthrough

"This is indeed a great gift that nature has given us," says Alessandra Corsi, a radio astronomer at the Texas Tech University in Lubbock. "It's an event that changes life."

24:41 Universal Time, August 17, with three physical tools: a twin detector 8 km Gravitation Observatory of Laser Interferometer Wave (FAM) at Hanford, Washington, and Livingston, Louisiana, and 6 miles. The virgin detector near Pisa, Italy, with dead waves she had never seen before. Four previous events lasted for a few seconds, and gravity waves pulsed at tens of cycles per second. The new siren sang 100 seconds on frequencies up to a thousand cycles per second. While the previous signal came from a pair of fast, massive spiral black holes, he discovered new neutron stars of lighter signals, 1.1 and 1.6 times more massive than the sun, turning relentlessly together, researchers announced parallel press conferences in Washington DC and Garching, Germany.

Gravity waves marked the beginning of a spectacular light emission. Because the black holes are gravitational fields left when very massive stars collapse into infinitesimal points, they do not contain any material that can emit light when a couple of isolated stars are behind. However, neutron stars are dead nuclei that are slightly less when stars explode as supernova and consist of almost pure neutrons in the most dense thing that exists. When such balls collide, they must project light residues to the light of all wavelengths. It just happened. Two seconds after the gravitational signal, only the "trigger" auto detector first noticed Hanford, the Gamma Fermi Space Telescope was in the orbit of the high-energy burst of photon called gamma-ray. In just a few minutes, the detectives of Livingston and the Virgin confirmed the gravity signal in their data.

MOBle Even so, LIGO lasted more than an hour to issue a detailed warning, The combination of gravity waves and electromagnetic observations has achieved at least three significant advances. First, he explains the origin of some gamma-ray explosions, the second most powerful known events in the cosmos and the joining of black holes. Since the 1990s, theoreticians have been thinking that an explosion is born less than two seconds when the neutron stars connect to create a black hole. (It is believed that the longest winds, which last for a few minutes, come from the collapse of massive single stars). The new result explains the brief blasts, explains Peter Mészáros, theorist of Pennsylvania State College. "That's great," he says. "If you have gravitational waves with an explosion, you know it must come from a double neutron star."

Second, the event reveals a hypothetical object called kiloons, because it lights a thousand times brighter than the ordinary new one. Since the two stars of the neutrons are driven and separated, they must emit atomic nuclei rich in neutrons, creating a canvas that altogether accounts for a small percentage of solar mass. These nuclei are strengthened by rapid neutron digestion, and then rapidly change their chemical identity by radioactive decomposition. A process called the acceleration of a neutron or a fast process should overshadow the lid for several days, and the light should be red with heavy elements that absorb blue wavelengths. That's what astronomers saw, says Brian Metzger, a theorist at Columbia University. "That's great, suddenly the curtain is rising and what we see is close to what we expected."

With a spectacular event on the stock market, the era of gravitational astronomy began. The next step is to see more events of this kind and start a statistical analysis on them, astronomers say. But for the time being, the whole community benefits from the irradiation of the discovery and the incredible success of their models. "Sometimes I wonder if we're just stupid," Howell explains. "These are moments like this one that work on science."
