Non-local dilaton coupling to dark matter: cosmic acceleration and pressure backreaction
L. Amendola, M. Gasperini, C. Ungarelli
A model of non-local dilaton interactions, motivated by string duality symmetries, is applied to a scenario of "coupled quintessence" in which the dilaton dark energy is non-locall…
Upper limits on gravitational wave emission from 78 radio pulsars
The LIGO Scientific Collaboration, B. Abbott, M. Kramer +1
We present upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO600 gravitational wave dete…
Upper Limits on a Stochastic Background of Gravitational Waves
LIGO Scientific Collaboration, B. Abbott
The Laser Interferometer Gravitational Wave Observatory (LIGO) has performed a third science run with much improved sensitivities of all three interferometers. We present an analys…
Gravitational waves, inflation and the cosmic microwave background: towards testing the slow-roll paradigm
Carlo Ungarelli, Pier Stefano Corasaniti, R. A. Mercer +1
One of the fundamental and yet untested predictions of inflationary models is the generation of a very weak cosmic background of gravitational radiation. We investigate the sensiti…
A family of filters to search for frequency dependent gravitational wave stochastic backgrounds
Carlo Ungarelli, Alberto Vecchio
We consider a three dimensional family of filters based on broken power law spectra to search for gravitational wave stochastic backgrounds in the data from Earth-based laser inter…
Did the dark energy always have a large Compton wavelength?
Bruce A. Bassett, Martin Kunz, David Parkinson +1
Until now all well-studied dark energy models proposed have very large Compton wavelengths, at all time and hence show no clustering on small scales. Evidence again…
