A coordinate-independent technique for detecting globally inhomogeneous flat topologies
Hirokazu Fujii
A flat Universe model supported by recent observations has 18 possible choices for its overall topology. To detect or exclude these possibilities is one of the most important tasks…

On the possibility for constraining cosmic topology from the celestial distribution of astronomical objects
Hirokazu Fujii, Yuzuru Yoshii
We present a method to constrain cosmic topology from the distribution of astronomical objects projected on the celestial sphere. This is an extension of the 3D method introduced i…

An improved cosmic crystallography method to detect holonomies in flat spaces
Hirokazu Fujii, Yuzuru Yoshii
A new, improved version of a cosmic crystallography method for constraining cosmic topology is introduced. Like the circles-in-the-sky method using CMB data, we work in a thin, she…
