为什么超大质量黑洞如此之大？他们疯狂地吞食星星。_我的网站

A | 北京时间1月16日，据外媒报道，天文学家对超大质量黑洞的形成有了新的认识。他们发现黑洞可以残酷地吞噬恒星。    (ECNS) – The 19th China-ASEAN Education Cooperation Week (CAECW) concluded in Guiyang, Guizhou Province, on Saturday, marking a significant push toward regional integration through digital learning and vocational training.    Nearly 450 educators, policymakers, and industry leaders gathered to advance cross-border collaboration under the theme "Empowering a Friendly Community through Smart Education."    This year's sessions produced several landmark agreements, including a framework for mutual recognition of vocational qualifications and the launch of the Ethnic Medicine AI Foundation Model, the first large-scale AI platform dedicated to traditional medicine.        From Summit to Year-Round Platform    Coinciding with the fifth anniversary of the China-ASEAN Comprehensive Strategic Partnership, the six-day event signaled a strategic shift in regional ties. Once a periodic summit, the CAECW is evolving into a year-round platform, with 60 additional activities scheduled across China, Thailand, Cambodia, Malaysia, and Indonesia this year-six of which will be hosted independently by ASEAN institutions.    Digital Transformation at the Forefront    Digital education dominated the agenda. Organizers launched the China-ASEAN Smart Education Capacity Co-Cultivation Program to narrow the regional digital divide by enhancing digital literacy and governance.    Scale: The existing Duocai Smart Academy platform already offers over 350 multilingual courses from 112 institutions to 129,000 users.    Access: A new ASEAN zone on China's National Smart Education Platform now provides virtual labs and AI-powered teaching tools.    Innovation: The newly unveiled China-ASEAN AI Joint Innovation Laboratory will focus on applying AI to preserve and research ethnic medical traditions, such as those of the Miao, Dong, and Bouyei peoples, specifically targeting ASEAN markets.    Breaking Barriers in Vocational Training    In a major breakthrough for labor mobility, the International Mutual Recognition Scheme for Vocational Education Learning Outcomes was officially released. Covering 34 fields-from cross-border e-commerce and smart manufacturing to healthcare-the scheme aims to dismantle institutional barriers to talent flow.    Complementing this, the "Guijiang Workshop" brand has expanded into a regional skills hub operating in Thailand, Laos, and Indonesia, exporting Chinese vocational standards in high-demand sectors like new energy and smart construction.    Youth and Innovation Take Center Stage    Youth engagement reached new heights, with the World University Innovation and Entrepreneurship Challenge attracting 1,007 projects from 149 universities across 11 countries. Peking University's team won the top prize for its cryo-electron microscopy technology platform.    Other highlights included esports tournaments at Guiyang's X-Sci-Fi Valley and the "Speaking ASEAN in Chinese" language program. Organizers announced plans to host over 5,000 international youths in Guizhou over the next year.    Strategic Outlook    Since its inception in 2008, the CAECW has hosted over 54,000 participants from nearly 90 countries. Beyond education, the week serves as a pillar of soft power diplomacy, supporting the New International Land-Sea Trade Corridor and providing landlocked Guizhou with a vital gateway to Southeast Asia.    "Education is the bridge, wisdom is the engine, and youth are the future," an organizer noted, emphasizing that the 2026 conclave marks not an endpoint, but a starting point for deeper, smarter regional cooperation. To ensure accountability, a year-round tracking system with project ledgers and quarterly reviews will monitor all signed agreements.                    。

B | 目前，首次探测到“恒星吞没事件”。2017年2月，“全空间超新星自动调查”发现了恒星吞噬现象，并将其命名为“2017bgt”。这一事件被认为是吞咽恒星事件或“潮汐崩溃事件”，因为黑洞周围的辐射比2004年观测到的要亮50倍以上。然而，在使用多个望远镜进行了广泛的观察之后，研究人员现在相信这是一种“黑洞进食”的新方法。领导这项研究的以色列特拉维夫大学的本尼·特拉赫滕布罗特博士说：“AT 2017bgt事件的突然亮起提醒我们潜在的潮汐引力。但我们很快意识到这次有点不寻常。这项研究目前发表在《自然天文学杂志》上。第一条线索是轻添加剂，这在这次潮汐事件中从未被发现。

C | 负责数据收集的Akawi博士强调，我们已经用太空望远镜和地面望远镜观测了这一事件一年多，我们所看到的与我们以前看到的完全不同。这些观察结果与特拉维夫大学的哈盖·内泽尔教授的理论预测相一致，他说：“早在20世纪80年代，我们就预言了一个吞噬周围气体的黑洞会产生轻元素。”特拉克滕勃罗特博士总结说，我们还不确定BLAC突然增加的确切原因。K孔“进料速度”。有许多方法可以加速大黑洞的快速增长，而大黑洞通常发生在较长的时间尺度上。

D | 我们想探测更多这样的事件，并通过几个共同工作的望远镜跟踪它们。来自美国、智利、波兰和英国的天文学家使用三种不同的空间望远镜，包括安装在国际空间站上的新的更好的望远镜，参与了观测和分析任务。最后，研究小组确定了另外两个最近报告的黑洞“开放事件”，这些黑洞的辐射特性与AT 2017bgt非常相似。

E | 目前科学界有两种关于超大质量黑洞诞生的理论。一个假设是，当一颗大质量恒星坍缩时，“黑洞种子”从一个质量约为太阳质量10-100倍的黑洞中发芽。然后，黑洞的种子通过与其他小黑洞合并并吸收周围的气体而长大。但它们必须以惊人的速度成长，才能达到数十亿年前在年轻宇宙中发现的超大质量黑洞的质量。最近发表的另一项研究支持这一假设，这表明至少有一些非常大的黑洞种子，其质量是太阳质量的10万倍，并且是在巨大的气体云坍塌时直接形成的。在这种情况下，黑洞的增长将开始跳跃，而且非常快。
