Photon-counting spectral phase-contrast mammography
E. Fredenberg, E. Roessl, T. Koehler +10
Phase-contrast imaging is an emerging technology that may increase the signal-difference-to-noise ratio in medical imaging. One of the most promising phase-contrast techniques is T…
Topological defects and gravity in theories with extra dimensions
Ewald Roessl
Various solutions to higher-dimensional Einstein equations coupled to a series of physically different sources are considered and their properties of localization of gravity discus…
Einstein static universe as a brane in extra dimensions
A. Gruppuso, E. Roessl, M. Shaposhnikov
We present a brane-world scenario in which two regions of space-time are glued together along a 3-brane with constant positive curvature such that {\em all} spatial dimensi…
Localizing gravity on a 't Hooft-Polyakov monopole in seven dimensions
Ewald Roessl, Mikhail Shaposhnikov
We present regular solutions for a brane world scenario in the form of a 't Hooft-Polyakov monopole living in the three-dimensional spherical symmetric transverse space of a seven-…
Living Inside a Hedgehog: Higher-dimensional Solutions that Localize Gravity
Tony Gherghetta, Ewald Roessl, Mikhail Shaposhnikov
We consider spherically symmetric higher-dimensional solutions of Einstein's equations with a bulk cosmological constant and n transverse dimensions. In contrast to the case of one…
