中新网北京4月23日电 记者孙自法报道,近日,一项发表在施普林格·自然旗下《自然-天文学》期刊的最新研究,利用先进的3D技术,为揭示黑洞周围耀斑的形成机制提供了前所未有的清晰视角。研究人员采用类似医学CT扫描的方法,对银河系中心的超大质量黑洞人马座A*(Sagittarius A*)附近的高能爆发事件进行了重建。

这项创新性的研究显示,人马座A*周边的耀斑可能源于吸积盘中等离子体的不稳定性。通过3D重建,科学家能够更直观地观察到这些耀斑如何在黑洞的强大引力作用下形成并释放出巨大的能量。这一技术的应用,使得天文学家能够以前所未有的细节,研究黑洞附近复杂且动态的物理过程。

论文作者指出,这些耀斑的产生并非随机,而是与黑洞附近物质的动态相互作用密切相关。他们推断,当这些物质以极高的速度旋转并接近黑洞时,由于引力的极端扭曲,可能导致等离子体结构的破裂,从而引发耀斑爆发。

这一突破性的发现对于理解黑洞物理学和宇宙学具有重要意义,不仅有助于科学家深入探索黑洞的性质,也为未来研究黑洞与周围环境的相互作用提供了新的工具和方法。研究人员表示,他们将继续运用这项技术,以期揭示更多关于人马座A*以及其它黑洞的秘密。

**News Title:** “3D Technology Unveils Secrets of Black Hole Flares: Astronomers Produce First Stereoscopic View of Sagittarius A* Eruptions”

**Keywords:** Black hole flares, 3D reconstruction, Astronomical breakthrough

**News Content:**

**BEIJING, April 23 (Xinhua) –** Journalist Sun Zifa reports that a recent study published in the journal _Nature Astronomy_ under Springer Nature has utilized advanced 3D technology to offer an unprecedentedly clear insight into the mechanisms behind flares around black holes. Researchers employed a method akin to medical CT scans to reconstruct high-energy eruptions near the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*).

This innovative research suggests that the flares around Sgr A* might originate from instabilities in the accretion disk’s plasma. Through 3D reconstruction, scientists can now observe more intuitively how these flares form and release enormous energy under the black hole’s intense gravitational pull. This technological application allows astronomers to study the intricate and dynamic physical processes in the vicinity of black holes with unparalleled detail.

The authors of the paper note that the flares do not occur randomly but are closely related to the dynamic interactions of matter near the black hole. They hypothesize that as this matter rotates at high speeds and approaches the black hole, extreme gravitational distortion might cause the plasma structures to break apart, leading to flare eruptions.

This groundbreaking discovery holds significant implications for understanding black hole physics and cosmology. It not only aids scientists in probing the nature of black holes more deeply but also furnishes new tools and approaches for future studies of the interaction between black holes and their surroundings. Researchers have expressed their intent to continue utilizing this technology to uncover more secrets about Sgr A* and other black holes.
