Letters: An actively accreting massive black hole in the dwarf starburst galaxy Henize?2-10, 470: 7332, 66–68, 3 February 2011 Henize 2-10中心发现一个袖珍型射电源:Henize 2-10(一个相对来说在我们附近的蓝色袖珍型矮星系)中的“星爆”引起天文学家关注已有几十年了,部分是由于其惊人的恒星形成速度——其恒星形成速度是“大麦哲伦云”的10倍。现在,在厘米射电波长及近红外波长对Henize 2-10所做的一项研究,显示其中心有一个袖珍型射电源,这与一个硬X-射线源在空间上巧合。该发现表明存在一个在活跃吸积的大质量黑洞,但却是一个与“核球”、“核星团”或任何其他明确定义的“核”都不相关的黑洞。这意味着Henize 2-10可能反映了以前没有观测到的黑洞和星系演化的一个早期阶段。

Letter: The Sagittarius impact as an architect of spirality and outer rings in the Milky Way, 477, 7364, 301303, 15 September 2011 重塑银河系的形状:自其十多年前被发现以来,作为我们银河系一个伴星系的“人马座矮星系”(Sgr),已被当作是与据信在整个宇宙中普遍存在的无数合并事件相似的一个“本地事件”。传统上,Sgr被当作是“银盘”的一个可以忽略的扰动者。对银河系对Sgr“内落”的反应所做新的模拟表明,实际情况正好相反:Sgr在决定“银盘”形态中扮演一个重要角色。过去的撞击触发了螺旋结构的形成,影响了“棒的演化”。

Letters: A close nuclear black-hole pair in the spiral galaxy NGC?3393, 477: 7365, 431–434, 22 September 2011

Letters: The alignment of molecular cloud magnetic fields with the spiral arms in M33, 479: 7374, 499–501, 24 November 2011  星系中的磁场在恒星形成中的作用:人们提出了很多机制来解释星系恒星形成,该过程被认为主要发生在富含尘埃和气体的星际分子云中。一些“云形成模型”认为,是否存在一个大型星系磁场在各个星际分子云的尺度上来说无关紧要,而另一些模型则认为,星系磁场强到足以将其方向施加到各个星际分子云上。利用安装在莫纳克亚山上的“亚毫米阵列”望远镜,Hua-bai Li Thomas Henning对来自“三角座”中的M33星系的磁场进行了观测。这个星座是离我们最近的、面朝我们的星座,有显著的光螺旋臂。他们发现了六个巨大的分子云团,这几个云团全都与那些螺旋臂的方向一致,说明M33中的大型磁场固定了这些云的方向。

Letters: Two ten-billion-solar-mass black holes at the centres of giant elliptical galaxies, 480: 7376, 215–218, 8 December 2011 黑洞大小的新“记录”:超大螺旋星系M87的中央黑洞质量为63亿个太阳质量,30多年来它一直被认为是宇宙中已知质量最大的黑洞。这篇论文报告了含有超过这个数字的黑洞的两个星系。NGC 3842有一个质量为97亿个太阳质量的黑洞;NGC 4889有一个质量与其差不多或更大的黑洞。明亮的类星体已经表明,在早期宇宙中存在质量如此大的黑洞,但却一直未能探测到。这些结果首次将早期的大质量黑洞与附近宇宙中的寄主星系联系了起来。

活动星系核

Letters: Broad-line active galactic nuclei rotate faster than narrow-line ones, 470: 7334, 366368, 17 February 2011 超大质量黑洞的质量比以前估计的要小很多:“活动星系核”(AGN)是宇宙中最亮的天体。它们是由质量在1000万个太阳质量和100亿个太阳质量之间的超大质量黑洞提供能量的,其周围是一个“宽发射线”(broad emission line)区域,这个区域很可能与一个吸积盘相关。人们对中央“宽发射线”区域的动态和结构很不了解,尽管在这个方面已经进行了超过30年的深入研究。现在,Wolfram Kollatschny Matthias Zetzl发现,在AGN光谱中所观测到的发射线宽度和发射线形状之间有一个根本性的关系,据此他们推测,内区域的几何对于快速转动的“宽线”天体来说是最平(flattest)的,而慢速转动的“窄线”AGN有一个更接近球形的结构。知道转动速度之后,就有可能推导出对中央黑洞质量的更准确的估计值——结果表明,这些黑洞的质量比以前所估计的小两到十倍。

Letters: Relativistic jet activity from the tidal disruption of a star by a massive black hole, 476: 7361, 421424, 25 August 2011  一个黑洞相对论喷射流的诞生:两个小组报告了对X射线源Swift J164449.3+573451的观测结果,它是在2011328日当其触发Swift Burst Alert Telescope时被发现的。Burrows等人报告,这个射线源在X射线波段的亮度自1990年以来已增大了超过1万倍,自2010年以来已增大了超过100倍。他们的结论是,我们正在观测来自一个超大黑洞的相对论喷射活动的开始。Zauderer等人得出一个相似的结论,他们是根据自己对一个与这个光源相关的“射电瞬变”的观测结果以及在其演化的第一个月在厘米至毫米波长所进行的广泛监测得出结论的。他们估计该黑洞的质量约为100万个太阳质量。

Letters: An origin of the radio jet in M87 at the location of the central black hole, 477: 7363, 185187, 8 September 2011射电喷射流和黑洞之间的关系:来自活动星系核(如附近星系M87)的射电喷射流,被认为是由物质向一个超大质量黑洞中的吸积提供能量的。关于这一“中心引擎”的相对位置和标志着该喷射流基部的明亮射电核,仍存在很多猜测。研究人员利用在六个频率所获得的M87的新的观测结果,以大约20微弧秒的准确性确定了该射电核的位置。这些数据显示,该“中心引擎”的位置靠近这个射电核,其距离在43 GHz处在14-23个“Schwarzschild 半径”内。

星系团

Letters: A massive protocluster of galaxies at a redshift of z??5.3, 470: 7333, 233–235, 10 February 2011 一个高红移“原星团”被发现:一个在红移值z = 5.3 处的大质量“原星系团”(其时间仅在“大爆炸”之后10亿年),已在来自“宇宙演化调查”(COSMOS)的数据中被发现。COSMOS是一个研究项目的名称,该项目将“哈勃太空望远镜”与地基天文望远镜结合在一起,对“六分仪星座”(Sextans)2平方度(square degree)的天域进行观测研究。这个“原星系团”占据一个直径超过13“百万秒差距”(400万光年)的超致密区域,富含分子气体和年轻恒星。其性质与星系形成模拟的预测结果一致,说明该“原星系团”将演化成一个大质量星系团,同在较低红移处所看到的那些星系团一样。

早期宇宙和星系形成

Letters: A distortion of very-high-redshift galaxy number counts by gravitational lensing, 469: 7329, 181-184, 13 January 2011 引力透镜效应对甚高红移星系观测结果的影响:重新离子化时期(这个时期宇宙正从“黑暗时期”形成,中性氢正被重新离子化)所发生的恒星形成活动的一个度量,可从红移值z > ~7处的高红移星系候选对象的数量获得。然而,由在我们与这些遥远天体之间的星系所产生的引力透镜效应会使问题复杂化。一项新的理论模拟研究表明,引力透镜效应很可能支配红移值z >~12的星系的所观测到的性质,在这个位置,仪器“极限星等”预计要比星系样本的特征星等更亮。这个因素可能会使(星系)数量发生一个数量级的改变。因此,今后的研究工作将需要把在高红移星系样本中的显著引力透镜效应考虑进去。

Letters: candidate redshift z??10 galaxy and rapid changes in that population at an age of 500?Myr, 469: 7331, 504–507, 27 January 2011 “哈勃超深场”数据中发现一个早期星系:对全部“哈勃超深场”数据所进行的一项“超深”搜索,发现了一个红移值为z 10的星系,这个红移值相当于该星系的年龄仅仅为“大爆炸”之后5亿年。这些数据还为当时的星系体密度(从而也为当时的恒星形成速度)提供了严格约束条件。本文作者们得出结论认为,在z 10 z 8之间的时间里,恒星形成速度加快了10倍,说明处在“重新离子化”时期核心的这一阶段是星系演化非常迅速的一个阶段。

Letters: Submillimetre galaxies reside in dark matter haloes with masses greater than 3?×?1011 solar masses, 470: 7335, 510-512, 24 February 2011 有“背景”的“亚毫米”星系:在远红外波长产生“银河系外背景”的、在光学上较暗的“亚毫米”恒星形成星系,单独进行研究是有挑战性的,但它们的平均性质却可以利用如背景密度变化的“角功率谱”等统计数字来确定。采用这种方法,Amblard等人在亮度波动“功率谱”的250350500微米处、在“弧分度角度盘”上观测到了超过线性预测的“过度成团”(excess clustering)现象。这表明“亚毫米”星系位于质量超过3000亿个太阳质量的暗物质晕中,这样一个直接测量结果将为改进关于星系形成和演化的理论模型增加有用的细节。

Letters: Imprints of fast-rotating massive stars in the Galactic Bulge, 472: 7344, 454457, 28 April 2011宇宙中的“第一批恒星”:NGC 6522(我们银河系中最古老的球状星团)很可能见证了宇宙化学富集过程的最早阶段,当时在“大爆炸”之后不久形成的大质量恒星产生了“金属”(比氦重的元素),后者被吸收进了一直存在到今天的低质量恒星中。然而,所报告的恒星中来自NGC 6522的元素丰度,却提供了关于它们从中形成的气体的性质的矛盾证据。对更早的光谱所做的重新分析(增添了钇和锶的丰度及碳的上限)表明,存在这样一个丰度模式,该模式能够由早期存在金属含量低的、快速转动的大质量恒星得到最好的解释。这些“转动的恒星”最有可能是宇宙中的“第一批恒星”。
