Black holes can get pretty big, but there's a special class that is the biggest of the big, absolute yawning monster black holes.
黑洞可能會(huì)很大，但有一種特殊的黑洞，它是那些就像張著大嘴的怪物一般的黑洞中最大的。

And astronomers seem to have found an absolute specimen, clocking in at 40 billion times the mass of the Sun.
天文學(xué)家似乎發(fā)現(xiàn)了這樣的一個(gè)黑洞，它達(dá)到了太陽(yáng)質(zhì)量的400億倍大。

It's at the centre of a galaxy called Holmberg 15A, a supergiant elliptical galaxy around 700 million light-years away, which in turn sits at the centre of the Abell 85 galaxy cluster.
它位于一個(gè)被稱為霍姆伯格15A的星系中心，這是一個(gè)（距地球）約7億光年遠(yuǎn)的超大橢圓星系，它位于阿貝爾85星系群中心。

The object is one of the biggest black holes ever found, and the biggest found by tracking the movement of the stars around it.
該目標(biāo)是迄今為止發(fā)現(xiàn)的最大的黑洞之一，也是通過追蹤它周圍的恒星運(yùn)動(dòng)所發(fā)現(xiàn)的最大的黑洞。

Previous calculations based on the dynamics of the galaxy and the cluster had resulted in Holm 15A* mass estimates of up to 310 billion times the mass of the Sun.
先前根據(jù)星系和星團(tuán)動(dòng)態(tài)得出的計(jì)算結(jié)果顯示，霍姆15A*星系可能是太陽(yáng)的3100億倍大。

However, these were all indirect measurements of the black hole. This new research marks the first direct measurement; the paper has been submitted to The Astrophysical Journal, and awaits peer review.
然而，這都是對(duì)黑洞的非直接測(cè)量。這項(xiàng)新研究標(biāo)志著第一次直接測(cè)量的實(shí)現(xiàn)；而且這篇論文已提交給《天體物理期刊》，目前在等待同行的評(píng)審。

"We use orbit-based, axisymmetric Schwarzschild models to analyse the stellar kinematics of Holm 15A from new high-resolution, wide-field spectral observations obtained with MUSE at the VLT. We find a supermassive black hole (SMBH) with a mass of (4.0 ± 0.80) × 1010 solar masses at the center of Holm 15A," the researchers wrote in their paper.
“根據(jù)用超大望遠(yuǎn)鏡通過MUSE軟件獲取的新的高分辨率廣角光譜觀測(cè)結(jié)果，我們用基于軌道的軸對(duì)稱施瓦西模型來分析霍姆15A星系的恒星運(yùn)動(dòng)學(xué)特性。我們發(fā)現(xiàn)了一個(gè)超級(jí)大的黑洞（SMBH），它位于霍姆15A星系的中心，是太陽(yáng)的 (4.0 ± 0.80) × 1010倍大，”研究人員在論文中寫道。

"This is the most massive black hole with a direct dynamical detection in the local Universe."
“這是在局部宇宙中通過直接動(dòng)力檢測(cè)發(fā)現(xiàn)的最大的黑洞?！?/div>
