Warp factor and the gravitational wave spectrum
David Andriot, Paul Marconnet, Dimitrios Tsimpis
A distinct signature of compact extra dimensions would be a Kaluza-Klein tower of gravitational waves. Motivated by this prospect, we compute the corresponding spectrum on a warped…

Intricacies of classical de Sitter string backgrounds
David Andriot, Paul Marconnet, Timm Wrase
Up-to-date, there is no known example of a classical de Sitter solution of string theory, despite several good candidates. We consider here two newly discovered 10d supergravity de…

New de Sitter solutions of 10d type IIB supergravity
David Andriot, Paul Marconnet, Timm Wrase
We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D5-branes and orientifold O5-planes, as well as a new Minkowski one. T…
