广义瑞士奶酪宇宙学:质量尺度

Generalized Swiss-cheese cosmologies: Mass scales

Cédric Grenon, Kayll Lake

摘要:

我们推广了瑞士奶酪宇宙学,以便包括相关边界表面的非零线性动量。在这些广义宇宙学的质量尺度的演变研究的背景下,而不必指定任何细节内的局部不均匀性的各种模型。我们发现,最终的有效引力质量和大小的演变不均匀性取决于他们的线性动量,但这些属性基本上不受背景模型的细节。

英文摘要:

We generalize the Swiss-cheese cosmologies so as to include nonzero linear momenta of the associated boundary surfaces. The evolution of mass scales in these generalized cosmologies is studied for a variety of models for the background without having to specify any details within the local inhomogeneities. We find that the final effective gravitational mass and size of the evolving inhomogeneities depends on their linear momenta but these properties are essentially unaffected by the details of the background model.
