超新星宇宙学:遗产与未来

Supernova cosmology: legacy and future

Ariel Goobar, Bruno Leibundgut

摘要:

第一代高红移超新星巡天发现了暗能量,引起了宇宙学之外的巨大兴趣,对基础物理学有着戏剧性的影响。利用超新星爆炸进行的距离测量是对宇宙膨胀历史的最直接的探测,使其成为研究宇宙结构和最大尺度引力性质的非常有用的工具。过去十年证实了最初的结果。Ia型超新星是获得高精度测量暗能量状态方程参数的领先技术之一,在不久的将来,它的时间依赖性。这些努力的成功取决于我们理解大量影响地球观测通量的效应的能力,这些效应主要是天体物理性质的。现在的前沿在于理解观察到的现象是否是由于真空能量,尽管它的密度不自然,或者一些奇异的新物理学。未来的调查将通过改进的校准程序解决系统性影响,并提供数千颗超新星进行详细研究。

英文摘要:

The discovery of dark energy by the first generation of high-redshift supernova surveys has generated enormous interest beyond cosmology and has dramatic implications for fundamental physics. Distance measurements using supernova explosions are the most direct probes of the expansion history of the Universe, making them extremely useful tools to study the cosmic fabric and the properties of gravity at the largest scales. The past decade has seen the confirmation of the original results. Type Ia supernovae are among the leading techniques to obtain high-precision measurements of the dark energy equation of state parameter, and in the near future, its time dependence. The success of these efforts depends on our ability to understand a large number of effects, mostly of astrophysical nature, influencing the observed flux at Earth. The frontier now lies in understanding if the observed phenomenon is due to vacuum energy, albeit its unnatural density, or some exotic new physics. Future surveys will address the systematic effects with improved calibration procedures and provide thousands of supernovae for detailed studies.
