On Gravitational Waves in Spacetimes with a Nonvanishing Cosmological Constant
J. Näf, P. Jetzer, M. Sereno
We study the effect of a cosmological constant on the propagation and detection of gravitational waves. To this purpose we investigate the linearised Einstein's equations with…
Galactic globular clusters contribution to microlensing events?
Fabiana De Luca, Philippe Jetzer
In this note we perform an analysis of the large set of microlensing events detected so far toward the Galactic center with the purpose of investigating whether some of the dark le…
Solar system tests of the cosmological constant
Philippe Jetzer, Mauro Sereno
We discuss the influence of the cosmological constant on the gravitational equations of motion of bodies with arbitrary masses and eventually solve the two-body problem. Observ…
Microlensing constraints on the Galactic Bulge Initial Mass Function
S. Calchi Novati, F. De Luca, Ph. Jetzer +2
Aims. We seek to probe the Galactic bulge IMF starting from microlensing observations. Methods. We analyse the recent results of the microlensing campaigns carried out towards the…
Substructures in lens galaxies: PG1115+080 and B1555+375, two fold configurations
Marco Miranda, Philippe Jetzer
We study the anomalous flux ratio which is observed in some four-image lens systems, where the source lies close to a fold caustic. In this case two of the images are close to the…
Q0045-3337: models including strong lensing by a spiral galaxy
M. Chieregato, M. Miranda, P. Jetzer
Aims. Falomo et al. (2005) discovered a disk-like galaxy at ~ 1.2 arcsec from the QSO Q0045-3337 by means of ESO VLT adaptive optics. They estimated a galaxy Einstein radius (for a…
