English to Portuguese: black holes General field: Science Detailed field: Astronomy & Space
Source text - English Our universe could be riddled with monster black holes, new research has suggested.
The revelation comes after a black hole with a mass of 17bn suns was found in a large, virtually isolated galaxy 200m light-years away.
Black holes are referred to as “supermassive” if they have masses of millions or billions of times more than the sun. Supermassive black holes with masses of more than 10bn suns have previously been found at the heart of large galaxies located in dense clusters in the universe. But this is the first time astronomers have found such an object lurking at the center of a large galaxy in a relatively empty area of the universe.
“We didn’t expect to see such a huge black hole in a small place,” said Professor Chung-Pei Ma, an author of the study from the University of California, Berkeley.
That, she added, opens up an intriguing possibility. With such galaxies more common than rich clusters, such supermassive black holes could be rife.
“What this is saying is that you don’t need these galaxy clusters to grow very massive black holes,” says Professor Poshak Gandhi of the University of Southampton, who was not involved in the study. “That throws a wrench in the works of our understanding of how these monster black holes form – it throws the field wide open.”
Translation - Portuguese Nosso universo pode estar impregnado com buracos negros monstruosos, sugere novas pesquisas.
A revelação veio depois que um buraco negro com a massa de 17 bilhões de sois foi encontrada em uma distante, praticamente isolada, galáxia à 200 milhões de anos luz.
Buracos negros são referidos como "super-massivo" se eles tem a massa de milhões ou bilhões de vezes mais que a do sol. Buracos negros super-massivos com massa de mais de 10 bilhões de sois foram previamente encontrados no coração de galáxias distantes localizadas em densas aglomerações no universo. Mas esta é primeira vez que astrônomos encontraram tal objeto espreitando no centro de uma galáxia distante, numa área relativamente vazia do universo.
"Nós não esperávamos ver um buraco negro tão grande num lugar tão pequeno" disse o professor Chung-Pei Ma, um dos autores do estudo da universidade de Califórnia, Berkeley.
Isso, acrescentou ela, abre uma possibilidade intrigante. Em galáxias mais comuns que os ricos aglomerados, buracos negros super-massivos podem ser abundantes.
"O que isso quer dizer é que você não precisa de aglomerado de galáxias para que um buraco negro muito massivo cresça" diz o professor Poshak Gandhi da universidade de Southampton, que não estava envolvido no estudo. "Isto arruína nossos estudos de como buracos negros monstruosos se formam - abrange muito o campo de pesquisa."
