Cosmic voids and induced hyperbolicity

Cosmic voids—the low density regions in the Universe—as characteristic features of the large-scale matter distribution, are known for their hyperbolic properties. The latter implies the deviation of photon beams due to their underdensity, thus mimicing the negative curvature. We now show that the hy...

Zusammenfassung:	Cosmic voids—the low density regions in the Universe—as characteristic features of the large-scale matter distribution, are known for their hyperbolic properties. The latter implies the deviation of photon beams due to their underdensity, thus mimicing the negative curvature. We now show that the hyperbolicity can be induced not only by negative curvature or underdensity but also depends on the anisotropy of the photon beams.
