Luminosity distance dispersion in Swiss-cheese cosmology as a function of the hole size distribution
Thippayawis Cheunchitra, Andrew Melatos, Rachel Webster
The luminosity distance-redshift (--) relation derived from Type Ia supernovae (SNe Ia) yields evidence for a nonzero cosmological constant. SNe Ia analyses typically…
Directional limits on persistent gravitational waves using LIGO S5 science data
J. Abadie, B. P. Abbott, R. Abbott +712
The gravitational-wave (GW) sky may include nearby pointlike sources as well as astrophysical and cosmological stochastic backgrounds. Since the relative strength and angular distr…
An Upper Limit on the Stochastic Gravitational-Wave Background of Cosmological Origin
The LIGO Scientific Collaboration, the Virgo Collaboration
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmologica…
