星系的真正来源
Where galaxies really come from
摘要:
观测到的宇宙大尺度均匀性与宇宙年龄是有限的这一事实不相容,这一基本悖论通过引入最初的超光速空间膨胀时期(称为宇宙暴胀)而被克服。暴胀也可以产生宇宙结构(如星系)形成所需的均匀性的微小偏差。这是通过所谓的粒子产生过程,通过暴胀与量子真空的结合来实现的。这一机制被解释并与黑洞的霍金辐射联系起来。所涉及的粒子的性质进行了讨论,并提出了使用大量的矢量玻色子场,而不是标量场的情况下,强调其独特的观测签名。最后,这些想法的一个特定的实施包括,它可以连接星系的形成,标准模型矢量玻色子和观察到的星系磁场。
英文摘要:
The fundamental paradox of the incompatibility of the observed large-scale uniformity of the Universe with the fact that the age of the Universe is finite is overcome by the introduction of an initial a period of superluminal expansion of space, called cosmic inflation. Inflation can also produce the small deviations from uniformity needed for the formation of structures in the Universe such as galaxies. This is achieved by the conjunction of inflation with the quantum vacuum, through the so-called particle production process. This mechanism is explained and linked with Hawking radiation of black holes. The nature of the particles involved is discussed and the case of using massive vector boson fields instead of scalar fields is presented, with emphasis on its distinct observational signatures. Finally, a particular implementation of these ideas is included, which can link the formation of galaxies, the standard model vector bosons and the observed galactic magnetic fields.
