Direct Observation of Cosmic Strings via their Strong Gravitational Lensing Effect: I. Predictions for High Resolution Imaging Surveys
Maria Alice Gasparini, Phil Marshall, Tommaso Treu +2
We use current theoretical estimates for the density of long cosmic strings to predict the number of strong gravitational lensing events in astronomical imaging surveys as a functi…
Matched filter for multi-transducers resonant GW antennas
Maria Alice Gasparini, Florian Dubath
We analyze two kinds of matched filters for data output of a spherical resonant GW detector. In order to filter the data of a real sphere, a strategy is proposed, firstly using an…
Microlensing modulation by quadrupole variation
Florian Dubath, Maria Alice Gasparini, Ruth Durrer
We investigate microlensing in the case where the lens is considered as an extended object. We use a multipolar expansion of the lens potential and show that the time-varying natur…
Gravitational wave detection by a spherical antenna: the angular sensitivity of resonators in the TIGA configuration and its variation with sidereal time and galactic longitude
Maria Alice Gasparini
Experimental projects using spherical antennas to detect gravitational waves are nowdays a concrete reality. The main purpose of this paper is to give a possible way of interpretin…
Experimental signatures of gravitational wave bursters
Florian Dubath, Stefano Foffa, Maria Alice Gasparini +2
Gravitational wave bursters are sources which emit repeatedly bursts of gravitational waves, and have been recently suggested as potentially interesting candidates for gravitationa…
