What happens if you put your head in the Geneva water jet? An inquiry-based physics activity exploring fluid dynamics
Maria Alice Gasparini
We describe a physics education activity for third-year Bachelor students, inspired by a humorous question about the Geneva water jet. The exercise engages students in key scientif…
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…
Fluctuations of the luminosity distance
Camille Bonvin, Ruth Durrer, M. Alice Gasparini
We derive an expression for the luminosity distance in a perturbed Friedmann universe. We define the correlation function and the power spectrum of the luminosity distance fluctuat…
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…
