加州理工的天文学家E·施特尔·菲尼（E.SterlPhinney）是超大质量黑洞领域的专家，目前在荷兰的内梅亨大学（RadboudUniversity）休学术假。他认为海曼的模型能够解释这颗类星体的闪动。

E. Sterl Phinney , a Caltech astronomer and expert on supermassive black holes currently on sabbatical at Radboud University in the Netherlands , agreed that Dr. Haiman 's model explains the quasar variations .

基于搜集的405个源的样本，本文应用了三种不同的计算方法：即ReverberationMapping方法、利用恒星弥散速度、利用短时标光变，分类讨论了其中心超大质量黑洞的质量；

On the basis of 405 collected AGN_S samples , here we have adopted three different methods to analyse the masses of the super massive black hole . They included : the reverberation mapping method , the stellar velocity method , and the short time scale method .

她进一步解释道，当两个巨大的星系融合之时，其中的超大质量黑洞也开始结合成一个黑洞。

When two big galaxies merge , she explains , their supermassive black holes combine .

最新研究表明：超大质量黑洞的旋转速度接近光速。

Supermassive black holes spin at speeds approaching the speed of light , new research suggests .

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。

This research suggests that not all supermassive black holes were formed in the quasar era .

现在人们已经普遍相信，几乎在每一个星系中央都存在着一个超大质量黑洞。

It is widely believed that a super massive black holes lies in the center of every galaxy .

范登柏希特别著迷于盘形星系与星系中心超大质量黑洞的形成过程。

Van den Bosch is particularly intrigued by the formation of disk galaxies and of massive black holes in galactic centers .

先前仅仅只认为超大质量黑洞才能制造这些高速恒星。

Previously , only the supermassive black hole there was thought to be able to produce these " hypervelocity " stars .

不过他也表示，找到距离如此相近的一对超大质量黑洞令人意外。

But it was surprising , he said , to find a pair of supermassive black holes that have gotten so close .

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。

The supermassive black holes that are still active , however , do not exhibit the same behavioral patterns as the distant quasars .

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。

我们已经透过重力影响，侦测到蛰伏的超大质量黑洞。这架望远镜能够侦测到体积比地球还小的系外行星。

These dormant supermassive black holes have indeed been detected through their gravitational influence . It should be capable of detecting exoplanets smaller than the Earth .

科学家们认为这些圆环结构可能来自超大质量黑洞碰撞产生的强大，并且大部分显示各向同性的能量爆发。

The scientists think that these circles stem from the results of collisions between supermassive black holes that released huge , mostly isotropic bursts of energy .

这就是所谓的活动星系核，有些人认为这是超大质量黑洞存在的最有力的证据。

This is what 's known as an active galactic nucleus , and some consider it the strongest proof for the existence of supermassive black holes .

太阳形成于大约45亿年前，距离位于星系中心的超大质量黑洞约2.6万光年。

The sun , located roughly 26000 light years from the supermassive black hole residing at the center of the galaxy , formed about 4.5 billion years ago .

过去的这个冬天，加州理工的一群天文学家发布论文称，一对超大质量黑洞似乎在朝着灾难性碰撞的轨迹运行，而这种碰撞可能会宣告该星系的落幕。

Last winter a team of Caltech astronomers reported that a pair of supermassive black holes appeared to be spiraling together toward a cataclysmic collision that could bring down the curtains in that galaxy .

不过，如果没有与星体或星际气体之间的相互牵引，超大质量黑洞不能靠近到能迅速走向碰撞的地步，而这种现象被称为“最后的秒差距”问题（秒差距是天文学距离单位，1秒差距等于3.26光年）。

But without gravitational interactions with stars or interstellar gas , supermassive black holes can 't get close enough to each other to go into a rapid death spiral , a situation known as the " final parsec " problem . ( A parsec is the astronomical standard of distance , 3.26 light-years . )

这个新发现的天体叫做HLX-1，是首个显示为中等质量的黑洞，介于恒星质量的黑洞和超大质量的黑洞之间。

The newly discovered object , called HLX-1 , is the first to show an intermediate weight between stellar-mass and supermassive black holes .

“如果两个星系碰撞和每个人都拥有一个超大质量的黑洞，应当有两个黑洞的时候，作为活动星系核转，说：”作者之一理查德Mushotzky，天文学教授UMCP。

" If two galaxies collide and each possesses a supermassive black hole , there should be times when both black holes switch on as AGN ," said coauthor Richard Mushotzky , professor of astronomy at UMCP .
