美国天文学家利用人工智能技术分析引力透镜图像
美国天文学家 人工智能技术 引力透镜图像
2017/9/26
美国斯坦福大学与SLAC国家实验室的研究人员近日宣布，利用神经网络的人工智能算法分析被称为“引力透镜”的复杂时空扭曲现象，可在不到1秒的时间内完成，比传统方法快了1000万倍以上。这一成果发表在最新一期出版的《自然》杂志上。引力透镜指大质量天体（如星系团）的引力改变了更远天体的光路，使之被望远镜观测时发生扭曲的现象。引力透镜提供了质量在宇宙空间中分布的线索，是研究暗物质与暗能量的重要途径。传统上，...

特大质量黑洞从星系获得“养料”方式揭示
黑洞 星系 天体物理学
2017/8/17
英国《自然》杂志2017年8月15日发表的一项天体物理学研究称，天文学家发现一特大质量黑洞从水母星系获得“养料”，并解释了这种“供养”的方式。
超大质量黑洞的质量可达太阳的数10亿倍至100亿倍，其亮度最终会使所在的整个星系相形见绌，甚至一些星系的演化会受其中心特大质量黑洞的影响。一般认为，大部分星系的中心都包含特大质量黑洞，包括在银河系中心同样占据着这样一个黑洞。但是，只有少数会吸积（指致密天...
