Did supermassive black holes need a helping hand to grow to be so big?
超大质量黑洞的形成是否须藉助于外力？

Progress in Research on the Variability of Sgr A*
银河系中心超大质量黑洞Sgr A*的光变研究进展

These dormant supermassive black holes have indeed been detected through their gravitational influence.
我们已经透过重力影响，侦测到蛰伏的超大质量黑洞。
4.
This research suggests that not all supermassive black holes were formed in the quasar era.
这些研究暗示，并非所有超大质量黑洞都是在类星体时代形成。
5.
Previously, only the supermassive black hole there was thought to be able to produce these "hypervelocity" stars.
先前仅仅只认为超大质量黑洞才能制造这些高速恒星。
6.
Interestingly, there is no evidence for massive black holes in the center of globular clusters, suggesting that these are fundamentally different from galaxies.
有意思的是,球状星系中心庞大质量黑洞没有证据,暗示这些基本不同于银河系。
7.
Sagittarius A is now agreed to be the most plausible candidate for the location of a supermassive black hole at the center of the Milky Way galaxy.
现在同意人马座A是银河系中心超大质量黑洞位置的最有可能的候选者。
8.
The supermassive black holes that are still active, however, do not exhibit the same behavioral patterns as the distant quasars.
但是，目前仍活跃的超大质量黑洞，其行为模式与遥远的类星体并不相同。
9.
Although today nearly all attribute AGNs to supermassive black holes, the situation was not so clear as recently as15 years ago.
虽然现今几乎所有的证据都指向了超大质量黑洞，但是在15年前却还是浑沌不明。
10.
To the telescopes of the day, a tight knot of young stars and supernova debris would look just like a supermassive black hole.
因为对当时的望远镜而言，一群紧密的年轻恒星和超新星破片，看起来就像是颗超大质量黑洞。
11.
When this matter fails onto the neutron star or black hole, a large amount of energy is released.
当这些物质降落到中子星或黑洞上时，会释放出大量的能量。
12.
On the other hand, galaxy-mass black holes are found in Active Galactic Nuclei (AGN).
另一种有星系质量大小的黑洞常发现存在于活跃的星系核心（AGN）。
13.
These are thought to have the mass of about 10 to 100 billion Suns.
这些黑洞的质量被认为有100亿－1000亿个太阳那么大。
14.
The black hole could then grow even stronger (from the star's mass) as to possibly absorb another.
吸收了恒星质量之后，黑洞进一步膨大，并有可能吞噬下一颗恒星。
15.
Black holes are the evolutionary endpoints of stars at least 10 to 15 times as massive as the Sun.
黑洞是恒星演化的终点，这些恒星的质量通常有10－15个太阳大

The mass of one of these suppressive black holes has recently been measured using radio astronomy.
对于这些有着巨大质量的黑洞，最近可利用射电天文学来测量它们的质量。
18.
The "surface" of a black hole is the so-called event horizon, an imaginary surface surrounding the mass of the black hole.
黑洞“表面”就是所谓的活动视界，一个想像的黑洞质量周围的。
