The first black hole in human history. EHT Co-operation Organization

Many of the above-mentioned “weeting circles” are familiar. It is the first black hole in human history. The black hole, located at the M87 galaxy centre near the Earth’s 55 million-year-olds, is one of the black holes with the greatest knowledge of the present universe, about 6.5 billion times the solar quality. In 2017, the incident visual telescope (EHT) was filmed into its “writing”.

Recently, an international research team led by Chinese scholars and researchers from the Chinese Academy of Sciences at Sea Astronomical Observatory, such as Sen, was replaced by a channel to see the M87 black hole for the first time. Photographs include not only “weet sweetings”, but also “end bars” that have been extended from the “sweet rings” to the farther, i.e. black holes.

As an extension of the EHT photograph, the new photograph for the first time showed black holes and the environment surrounding it. On 26 April, the results were published in Nature.

The “bet sweetings” have led to obesity.

Black holes are a powerful time and space region, and nothing, including light, can escape. It can “feed” everything close to it.

New observations were made by astronomers using a 3.5-mm wave. In black hole photographs they have taken, it remains clear that the “sweet rings” — the black holes are centred around the heat-forward gas, which is constantly spreading radiation and forming a ring. At the same time, the gas that had been “delivered” in the vicinity of the black hole was also taken, and the sweet rings were overwhelmed.

“We have previously seen black holes and spectacles in separate images, but now we have a full picture of black holes and vents in a new wave.” The first author of the paper, such as Sen, told the Chinese Science Journal.

“We can see how the streams have emerged from the ring structure around the central ultra-quality black hole, and we can also measure the diameter of the ring structure around the black hole in another wave.” Thomas Krichbaum of the Map Radio Astronomy Institute said.

Through this landscape, astronomers received some new insights on black holes.

They found that “weet rings” were more “ obesity” than before. “The observations of this observation are 3.5 mm long, while the EHT observations are 1.3 mm long, and we have seen a much larger and stronger ring structure. This suggests that additional radiation can be found in new images of substances falling into black holes. This also enables us to learn more fully about the physical processes around black holes.” Road, as Sen.

They also found that black holes were not “verything”. “It consumes only a small proportion of the substances at a very low rate. Thus, in order to understand the physical origin of this larger, more ring, we have to use computer simulations to test different situations. In the end, we conclude that the lighting is more circumscribed to us and more relevant to the flow of adhesion.” Keichi Asada, Institute of Astronomy and Astrophysics, Taiwan District.

In addition, from the data they have seen some “amazing things”. Kazuo Hada, Japan’s National Astronomical Observatory, said: “In the internal region close to black holes, the breadth of radiation is more than expected. This may mean that there is not only a gas in the vicinity of the black hole, but also a “wind” blow, causing curing and confusion around the black hole.”

However, as Sen indicated, despite the discovery of many new phenomena, “the superquality black holes in the central galaxies are still unconstructed”.

Although many questions were not answered, both authors of the paper gave a high level of appreciation. A drafter stated: “The study is unique, thematic and dynamic and can generate general interest and merit publication in the Natural Journal.” Another drafter assessed: “This work is timely and is an important step in understanding the formation and integrity of galaxies of activity”.

The study was led by Chinese scholars, such as Sen, and was composed of 17 countries and territories, 64 research units, totalling 121. The global 16 radio telescopes were used to form a telescope with a calibre equivalent to a geodiameter.

The 16 radio telescopes consist of 14 telescopes of the Global Mills, the Atakama large-scale millimetre/submm wave array in Chile, and the Greenlandic telescope on Greenland Island.

The new black hole photograph was taken from 14 to 15 April 2018 five years ago, but it was not officially published today.

“After the initial processing of data, we have taken note of the unprecedented new features from the data. Five years later, after complex data processing and graphic processes, the results were repeatedly validated and confirmed before they were finally released.” Road, as Sen.

In the process of processing “living data” into “skilful data”, they conducted four “inter-related” analyses of very long baseline interferometry techniques and corresponding “relevant reprocessing” analyses. “All have overcome the tide of returning workers and have received the most reliable `know data’.” Road, as Sen.

The research team also faced unprecedented challenges in rebuilding observational images from “skilful data”. “This is a very visual image that contains many constituents and that the brightness of these components varies considerably. Through the experience of bringing together many partners across the globe, we have overcome these difficulties through various attempts and repeated certification.” Road, as Sen.

Photographs of “colour” will also be taken.

The next objective of the international research team on the road, such as Sen and his title, has been to give black holes with EHT.

The so-called “colour” is black holes in different observations. “Further observations and powerful telescopes will continue to uncover their mysterious veils.” Longho Park of the Korean Institute of Astronomical and Space Sciences stated that “future-mm observations will study the evolution of the M87 black hole over time and will receive a multi-coloured picture of the black hole region of the M87 centre by combining images of different colours of the “fire-raying””.
