Abstract

The currently available empirical evidence on the star formation processes in the extreme, high-pressure environments induced by galaxy encounters, mostly based on high-resolution Hubble Space Telescope imaging observations, strongly suggests that star CLUSTER formation is an important and perhaps even the dominant mode of star formation in the starburst events associated with galaxy interactions. The production of"super star clusters"(SSCs; luminous, compact star clusters) seems to be a hallmark of intense star formation, particularly in interacting and starburst galaxies. Their sizes, luminosities, and mass estimates are entirely consistent with what is expected for young Milky Way-type globular clusters (GCs). SSCs are important because of what they can tell us about GC formation and evolution (e.g., initial characteristics and early survival rates). They are also of prime importance as probes of the formation and (chemical) evolution of their host galaxies, and of the initial mass function in the extreme environments required for cluster formation. Recent evidence lends support to the scenario that Milky Way-type GCs (although more metal rich), which were once thought to be the oldest building blocks of galaxies, are still forming today.

极端星暴环境下的星团形成
目前可获得的关于星系碰撞引起的极端高压环境下恒星形成过程的经验证据,主要基于哈勃太空望远镜的高分辨率成像观测,强烈表明星团形成是与星系相互作用相关的星爆事件中恒星形成的重要甚至主导模式。超级星团(ssc)的产生;明亮紧凑的星团似乎是强烈恒星形成的标志,特别是在相互作用和星暴星系中。它们的大小、光度和质量估计与对年轻的银河系型球状星团(GCs)的预期完全一致。ssc很重要,因为它们可以告诉我们GC的形成和演化(例如,初始特征和早期存活率)。它们对于探测宿主星系的形成和(化学)演化,以及在星系团形成所需的极端环境下的初始质量函数也是至关重要的。最近的证据支持了这样一种假设,即曾经被认为是星系最古老的基石的银河系型gc(尽管更富含金属),今天仍在形成。
