伽马射线暴宿主星系作为星系形成和演化的探针

Gamma-ray Burst Host Galaxies as Probes of Galaxy Formation and Evolution

Emily M. Levesque

摘要:

宿主星系是探测产生伽马射线暴(GRB)的诞生环境的一种极好的手段。调查长持续时间的伽玛暴(LGRB)的主机环境和ISM属性产生了有趣的新结果与LGRB祖模型的重要影响。这些宿主星系的研究对于评估LGRB在高红移下作为恒星形成和金属丰度的潜在示踪剂的效用也是至关重要的,特别是当考虑对z ~ 6以上宿主星系性质的影响时。我将总结我们小组对LGRB宿主星系的最新研究,并讨论对我们理解这些事件的祖先,能量学,余辉性质和宇宙学应用的影响。

英文摘要:

Host galaxies are an excellent means of probing the natal environments that generate gamma-ray bursts (GRBs). Surveys of long-duration GRB (LGRB) host environments and their ISM properties have produced intriguing new results with important implications for LGRB progenitor models. These host studies are also critical in evaluating the utility of LGRBs as potential tracers of star formation and metallicity at high redshifts, particularly when considering the implications for properties of host galaxies above z ~ 6. I will summarize our group's latest research on LGRB host galaxies, and discuss the resulting impact on our understanding of these events' progenitors, energetics, afterglow properties, and cosmological applications.
