Look at the first image of a superb black negro in our galaxy

(CNN Español) –– For example, the astronomers will be able to capture the first image of a black massive water in the center of our galaxy, Via Láctea, known as Sagittarius A *. The European Observatory (ESO, in English) informs in a communication that this image is “proportional to a record of the fact that the object is a little black and a lot of good things to work on”.

This photo is a direct observation that confirms the presence of Sagittarius A *, as the palpitating heart of this galaxy.

Los agujeros negros no emiten luz, pero la imagen muestra su sombra rodeada por un anillo brillante, que es luz desviada por la gravedad del agujero negro. The astronomers dieron that the black man is 4 million times more massive than our Sol.

“Decades ago, the astronomers were convinced that he was in the heart of our galaxy, which sent the stars in orbits in the grasses of their name,” said Michael Johnson, astrophysicist at the Smithsonian Institution communicated.

“Con este imagen nos hemos acercado mil veces mas ma estas orbitas, donde la gravedad crece un millón de veces más fuerte. En este rango cercano, el agujero negro acelera la materia a una velocidad cercana a la de la luz y tuerce los caminos de los fotones en el (espacio-tiempo) deformado “, añadió.

Captured a black man in the team

The image captured the Event Horizon Telescope (EHT), a formation that unio acho observers of radio existents en todo el planeta para formar a solo telescopio virtual “del tamaño de la Tierra”, explicitly el ESO. “The telescope left the name of the horizon of successors, the limit of black water is almost as high as possible to escape the light,” said the observatory. There are about 300 researchers from 80 institutions.

De hecho, la imagen que ahora conocemos del agujero negro Sgr A * es un promedio de las diferentes imágenes que la el EHT ha extraído de sus observationes de 2017.

El agujero negro está a unos 27.000 años luz de la Tierra. Our solar system kills one of the spiral brazas of Via Láctea, because we are so far from the galactic center. If we look at it in our nocturnal night, the black negro will be able to have the same tamaño as a rosquilla sent on the moon.

“We are surprised that the tamaño del anillo coincides with the predictions of the Theory of General Relation of Einstein,” said Geoffrey Bower, EHT project researcher at the Institute of Astronomy and Astrophysics, Academia Sinia, Taipei.

“These observations are preceded by a great increase in our understanding of what happened in the very center of our galaxy, and offer new events about how these black giants interact with their entorns,” he said.

The results of this disclosure are published in the games in a special edition The Astrophysical Journal Letters.

Looking for the black man

Astronomos les tomó 5 años poder captar y confirmar esta imagen y este descubrimiento. Previously, the scientific observers were shooting orbiting an object massive and invisible in the center of the galaxy.

The 2020 Nobel Prize in Physics will be awarded to Roger Penrose, Reinhard Genzel and Andrea Ghez for their discoveries about the black aguires. Entre ellos, la recordcia compartida por Ghez y Genzel acerca de la masa del objeto en el centro de la Vía Láctea.

“Now we know that the black negro absorbed the gas and the light on his alder, llevandolos and a pose without a fund,” said Ramesh Narayan, an astrophysical theorist at the Harvard & Smithsonian Center for Astrophysics, in communication. “This image confirms decades of theoretical work to understand how to feed the black people,” he said.

This is the second image that will capture a black negro. The example of a hit by EHT that pudo obtener photos of M87 * in the heart of the galaxy Messier 87, killed 55 million years ago, in 2019.

These are the first few images of black people. A iz izquierda está M87 * ya la derecha Sagittarius A *.

Aunque las dos imágenes parecen similares, Sagittarius A * es majs de 1.000 veces más pequeño que M87 *.

“We have two different types of galaxies completely different and the masses of black and white very different ones. But the heart of these black and white animals is extremely unrelated,” said Sera Markoff, co-president of the EHT Council of Scientists and a professor of theoretical astrophysics. Amsterdam, in communication.

Capturing an imaginary image

Aunque el agujero negro de la Vía Láctea is closer to the land of Tierra, captures su imagen fue mucho más difícil.

“The gas in the evening of the black agronomists was built on the mass of the velocity, the house was opened quickly, the mayor of Sgr A * and M87 *, the signal of the EHT Chi-kwan Chan, the Steward Observatory, the Department de Astronomía y el Instituto de Ciencia de Datos de la Universidad de Arizona, dijo en un komunicado.

Pero mientras el gas tarda de dias a semanas en orbitar el M87 *, que es más grande, en el Sgr A *, mucho más pequeño, completa una órbita en solo minutos. Esto significa que el brillo y el patrón del gas alrededor de Sgr A * cambiaba rapidamente a medida que el EHT lo observaba. Era un poco como tratar de tomar una imagen clara de un cachorro que persigue rapidamente su cola “.

Si los agujeros negros supermasivos M87 * y Sagittarius A * estuvieran uno al lado del otro, Sagittarius A * quedaría eclipsado por M87 *, que es más de 1.000 veces más masivo.

The global astronomers have decided to release new tools to allow the rapid movement of the gas of Sagittarius A *. The image of the obturator is a combination of different photos that the team has. Captar la imagen de Sagittarius A * fue como tomar tomo foto de un grano de sal en la ciudad de Nueva York usando una camara en Los Ángeles, según explicaron investigadores del Instituto de Tecnología de California.

“This image of the Horizon Telescope requires more than just a photo of telescopes in high-altitude mounts. It is a product of telescopic observations, technically defective and innovative computational algorithms,” said Katherine Bouman, Professor of Education and Science. computer science and mathematics science, electrical engineering and astronomy in Caltech, a major press conference.

Bouman also works in capturing the image of M87 * in 2019. To catch the image of Sagittarius A * can look for borrosa, “it is one of the most important images you have ever created,” said Bouman.

Each telescope is pressed at the limit, which is limited to the limit of diffraction, the maximum characteristics that can be observed.

“Ye es basicamente el nivel que estamos viendo aqui,” said Johnson at the press conference. .
