一个新的III超新星概率统计模型：$Λ$ CDM和WDM宇宙学的区分
A New Statistical Model for Population III Supernova Rates: Discriminating Between $Λ$CDM and WDM Cosmologies
摘要：
随着新的观测设施即将投入使用，发现和描述来自第一批恒星的超新星将为宇宙黑暗时代的结束开辟另一个观测窗口。基于早期恒星形成的半解析合并树模型，我们限制了星族III超新星的速率。我们发现，我们的方法再现人口III超新星率的大规模宇宙学模拟非常好。我们的计算效率高的模型使我们能够调查一个大的参数空间，并探索广泛的不同的情况下，人口III恒星形成。我们的计算表明，第一次超新星的观测可以用来区分冷和暖暗物质模型，并限制后者相应的粒子质量。我们的预测还可用于优化调查策略，目标是最大限度地提高超新星检测率。
英文摘要：
With new observational facilities becoming available soon, discovering and characterising supernovae from the first stars will open up alternative observational windows to the end of the cosmic dark ages. Based on a semi-analytical merger tree model of early star formation we constrain Population III supernova rates. We find that our method reproduces the Population III supernova rates of large-scale cosmological simulations very well. Our computationally efficient model allows us to survey a large parameter space and to explore a wide range of different scenarios for Population III star formation. Our calculations show that observations of the first supernovae can be used to differentiate between cold and warm dark matter models and to constrain the corresponding particle mass of the latter. Our predictions can also be used to optimize survey strategies with the goal to maximize supernova detection rates.
