An axisymmetric object-based search for a flat compact dimension
An axisymmetric object-based search for a flat compact dimension
A method is presented for searching for a hypertorus symmetry axis by means of the alignment of distant objects. This offers greater sensitivity than previously proposed object-based methods that rely on accurate true distances. When it is applied to the catalogue of objects with z > 1, we find no evidence for a compact dimension. We deduce a lower limit on the compact dimension size, D > 0.9 of the distance to the cosmic horizon. This is consistent with independent constraints from the recent analysis of the WMAP microwave background data.

Abstract
A method is presented for searching for a hypertorus symmetry axis by means of the alignment of distant objects. This offers greater sensitivity than previously proposed object-based methods that rely on accurate true distances. When it is applied to the catalogue of objects with z > 1, we find no evidence for a compact dimension. We deduce a lower limit on the compact dimension size, D > 0.9 of the distance to the cosmic horizon. This is consistent with independent constraints from the recent analysis of the WMAP microwave background data.
