论文摘要
中央分子区域(CMZ)是在银河系中由银河驱动的物质运输产生的最内向的几百个parsec中分子气的环状积聚。 CMZ是银河系中最极端的恒星形成环境。大规模动力学和极端星际介质条件的独特组合,其特征是高密度,温度,压力,湍流运动和强磁场,使CMZ成为测试电流恒星和行星地层理论的理想区域。我们回顾了该领域的最新观察和理论进步,并将其结合起来,以在最接近的银河系核中恒星形成的背景下,绘制物质和能量周期的全面,多尺度和多物理图。
The Central Molecular Zone (CMZ) is a ring-like accumulation of molecular gas in the innermost few hundred parsecs of the Milky Way, generated by the inward transport of matter driven by the Galactic bar. The CMZ is the most extreme star-forming environment in the Galaxy. The unique combination of large-scale dynamics and extreme interstellar medium conditions, characterised by high densities, temperatures, pressures, turbulent motions, and strong magnetic fields, make the CMZ an ideal region for testing current star and planet formation theories. We review the recent observational and theoretical advances in the field, and combine these to draw a comprehensive, multi-scale and multi-physics picture of the cycle of matter and energy in the context of star formation in the closest galactic nucleus.
