疯狂吸收物质的超大质量黑洞被探测到产生从未见过的“强风”

  A team of astronomers had returned to observe an earlier discovered quasar after developing new methodology and resorting to a telescope sitting atop dormant volcano Maunakea in Hawaii,only to make a stunning revelation.

  在发展了新的研究方法并借助于位于夏威夷休眠火山Maunakea顶上的望远镜之后,一队天文学家对一些较早发现的类星体进行了重新观察,给人以惊人的启示。

  Scientists recently made a remarkable discovery as they detected massive winds spurting forth from a quasar they were observing,according to research published on 1 March in the Astrophysical Journal.

  根据3月1日在《天体物理学杂志》上发表的研究,科学家们最近有一个惊人的发现,他们正在观测的类星体中突然迸发出剧烈大风。

  The powerful thrust of the registered gusts was of a magnitude never seen previously.

  登记的阵风的强大推力是以前从未发现过的。

  A quasar is a supermassive black hole which is in a feeding frenzy,accelerating particles it cannot absorb to such impressive velocity that they reach nearly the speed of light,shooting out from the luminous space object in jet-like steams.The process is also often accompanied by winds permeated through the surrounding galaxy.

  类星体是一个超大质量的黑洞,它处于一个疯狂的进食状态,它无法以令人印象深刻的速度吸收加速的粒子,以至于它们几乎达到光速,以喷射状的蒸汽从发光的太空物体中射出。这个过程通常还伴随着风吹过周围的星系。X

  "While high-velocity winds have previously been observed in quasars,these have been thin and wispy,carrying only a relatively small amount of mass,"said Sarah Gallagher,an astronomer at Western University in Canada and lead author on the new research,in a University statement.

  据加拿大西部大学的天文学家莎拉·加拉格尔(Sarah Gallagher)发布的声明说:“虽然以前在类星体中观察到了高速风,但它们却又薄又稀疏,仅携带相对少量的质量。”

  Elaborating further on the research,entitled“Discovery of a Remarkably Powerful Broad Absorption-line Quasar Outflow in SDSS J135246.37+423923.5”,the astronomer added:

  天文学家进一步阐述了题为“发现SDSS J135246.37+423923.5中极强大的宽吸收线类星体外流”的研究,并补充说:

  "The outflow from this quasar,in comparison,sweeps along a tremendous amount of mass at incredible speeds.This wind is crazy powerful,and we don't know how the quasar can launch something so substantial."

  “相比之下,该类星体的外流物以令人难以置信的速度随着巨大的质量扫掠。这种狂风非常强大,我们不知道类星体是如何发射出如此巨大的阵风的。”

  The quasar that aided the astronomers in their discovery,dubbed SDSS J135246.37+423923.5,is produced by a supermassive black hole boasting a mass more than 8 billion times that of the Sun,according to the team.

  研究小组说,被称为SDSS J135246.37+423923.5的类星体是由一个质量超过太阳80亿倍的超大质量黑洞产生的,被称为SDSS J135246.37+423923.5。

  Originally discovered by Sloan Digital Sky Survey,a project that maps the universe,the astronomers had resumed a study of the object with the help of the Gemini North telescope strategically placed on dormant volcano Maunakea in Hawaii.

  天文学家最初是由斯隆数字天空测量公司(Sloan Digital Sky Survey)发现的,该项目是对宇宙进行映射的项目,天文学家借助战略性地放置在夏威夷休眠火山Maunakea上的北双子座(Gemini North)望远镜,重新开始了对该物体的研究。

  ​A new approach had been employed to study this specific type of quasar,referred to as a broad absorption line quasar.

  他们采用了一种新方法来研究这种被称为宽吸收线类星体特殊类型的类星体。

  "We were shocked—this isn't a new quasar,but no one knew how amazing it was until the team got the Gemini spectra,"said Karen Leighly,an astronomer at the University of Oklahoma and co-author of the study.

  俄克拉荷马大学的天文学家,该研究的合著者卡伦·利利(Karen Leighly)说:“我们对此感到震惊——这不是新的类星体,但是直到团队获得双子星座光谱之前,没人知道它有多么惊人。”

  在2015年8月27日发布的NASA插图中可以看到Markarian 231,这是在离地球最近的类星体宿主星系中心发现的一个双黑洞系统。

  "These objects were too hard to study before our team developed our methodology and had the data we needed,and now it looks like they might be the most interesting kind of windy quasars to study."

  “在我们的团队发展我们的研究方法并获得我们需要的数据之前,对这类物体的研究是极为困难的,现在看来它们可能会是最有意思的拥有强风的类星体。”

  The results of the study suggest the quasar in question is generating the most powerful winds scientists have ever witnessed.What renders the detected phenomenon even more important is that astronomers claim such winds are essential to“sculpting”surrounding galaxies.

  研究结果表明,相关类星体正在产生科学家们目睹的最强大风。使该现象更加重要的是,天文学家声称这种风对于“塑造”周围的星系至关重要。

  As the team voiced hope other similar quasars could be detected in subsequent studies,Hyunseop Choi,a graduate student at the University of Oklahoma and first author of the study added:

  正如研究组希望在以后的研究中发现其他类似的类星体一样,俄克拉荷马大学的研究生,该研究的第一作者蔡元秀(Hyunseop Choi)补充说:

  "We don't know how many more of these extraordinary objects are in our quasar catalogs that we just don't know about yet.There could be more of these quasars with tremendously powerful outflows hidden away in our surveys."

  “我们不知道尚不知晓的类星体目录中还有多少这种非同寻常的星体。在我们的调查中,可能会有更多这类类星体具有强大的外流。”
