Decaying dark energy in higher-dimensional gravity
(EDP Sciences, 2007)Aims. We use data from observational cosmology to put constraints on higher-dimensional extensions of general relativity in which the effective four-dimensional dark-energy density (or cosmological “constant”) decays with ... -
Dust/gas correlations from Herschel observations
(EDP Sciences, 2010)Context: Previous Spitzer and IRAS observations of the LMC suggest an excess of FIR emission with respect to the gas surface density traced by 12CO rotational emission lines and H i 21 cm emission. This so-called “FIR ... -
The mass-loss return from evolved stars to the Large Magellanic Cloud. III. Dust properties for carbon-rich asymptotic giant branch stars
(EDP Sciences, 2010)We present a radiative transfer model for the circumstellar dust shell around a Large Magellanic Cloud (LMC) long-period variable (LPV) previously studied as part of the Optical Gravitational Lensing Experiment (OGLE) ... -
Tidal acceleration of ultrarelativistic particles
(EDP Sciences, 2005)We investigate the motion of free relativistic particles relative to the ambient medium around a gravitationally collapsed system. If the relative speed exceeds a critical value given by c/√2, the gravitational tidal ...
