Time-dependent gravitating solitons in five dimensional warped space-times
Massimo Giovannini
Time-dependent soliton solutions are explicitly derived in a five-dimensional theory endowed with one (warped) extra-dimension. Some of the obtained geometries, everywhere well def…
Gravitating multidefects from higher dimensions
Massimo Giovannini
Warped configurations admitting pairs of gravitating defects are analyzed. After devising a general method for the construction of multidefects, specific examples are presented in…
Old ideas and new twists in string cosmology
Massimo Giovannini
Some of the phenomenological implications of string cosmological models are reviewed, with particular attention to the spectra of the tensor, scalar and vector modes of the geometr…
Graviphoton and graviscalars delocalization in braneworld scenarios
Massimo Giovannini
A manifestly gauge-invariant theory of gravitational fluctuations of brane-world scenarios is discussed. Without resorting to any specific gauge choice, a general method is present…
Gravitational Radiation from String Cosmology
R. Brustein, M. Gasperini, M. Giovannini +1
A spectrum of relic stochastic gravitational radiation, strongly tilted towards high frequencies, and characterized by two basic parameters is shown to emerge in a class of string…
