Testing General Relativity vs. Alternative Theories of Gravitation with the SaToR-G Experiment
Lucchesi D. M., Anselmo L., Bassan M., Lucente M., Magnafico C., Pardini C., Peron R., Pucacco G., Visco M.
A new experiment in the field of gravitation, SaToR-G, is presented. The experiment aims to compare the predictions of different theories of gravitation in the limit of weak-field and slow-motion. The ultimate goal of the experiment is to look for possible "new physics" beyond the current standard model of gravitation based on the predictions of General Relativity. A key role in the above perspective is the theoretical and experimental framework within which to confine our work. To this end, we will try to exploit as much as possible the framework suggested by Dicke over fifty years ago.Source: 1st Electronic Conference on Universe (ECU 2021), On-line Virtual Event, 22-28/02/2021

General Relativity Accuracy Test (GReAT): new configuration for the differential accelerometer
Iafolla Valerio, Lucchesi David, Nozzoli Sergio, Ravenna Matteo, Santoli Francesco, Shapiro Irvine, Lorenzini Enrico, Cosmo Mario, Bombardelli C., Ashenberg J., Cheimets P., Glashow S.
We presents the results of an activity concerning the test of the Einstein Weak Equivalence Principle with an accuracy of about 5 x 10^-15. The experiment will be performed in an "Einstein elevator" using a differential accelerometer with a final sensitivity of about 10^-14 g/Hz^1/2. The differential accelerometer is spun about an horizontal axis at a frequency in the range 0.5-1 Hz in order to modulate, during the free fall, the signal from a possible violation of the Equivalence Principle. In the paper the perturbing effects with the same signature of the possible violation are analyzed and constrained. The experimental results obtained in the laboratory with a first prototype of the differential accelerometer are discussed, comparing this results with those obtained using a new prototype.Source: Advances in space research 47 (2011): 1225–1231. doi:10.1016/j.asr.2010.11.028

The LAGEOS satellites orbit and Yukawa-like interactions
Lucchesi, David
LAGEOS II general relativity pericenter precession has been analysed in terms of the errors produced by the mismodelling of both the gravitational and non-gravitational perturbations acting on the satellite orbit. The accuracy in the pericenter determination may be considered as an upper-bound value for the estimate of the strength alpha of a possible new-long-range-interaction described by a Yukawa-like potential. In the present work we have focused on the constraints in alpha that can be obtained with the current best multi-satellites gravity field model EGM96 (alpha < 2.6 x 10^-10) and also with the first promising models from the CHAMP (alpha < 1.8 x 10^-10) and GRACE (alpha < 1.2 x 10^-10) gravimetric missions. These results represent, potentially, an improvement of two or three orders-of-magnitude with respect to the best constraints obtained in the past with Earth-LAGEOS and Lunar-LAGEOS data (|alpha| < 10^-5 -- 10^-8). The impact of the non-gravitational perturbations mismodelling in the final error budget has been determined together with the improvements obtainable in the constraint of the strength a with the proposed LARES satellite.Source: Advances in space research 47 (2011): 1232–1237. doi:10.1016/j.asr.2010.11.029

Accurate measurement in the field of the earth of the general-relativistic precession of the LAGEOS II pericenter and new constraints on non-Newtonian gravity
Lucchesi D., Peron R.
The pericenter shift of a binary system represents a suitable observable to test for possible deviations from the Newtonian inverse-square law in favor of new weak interactions between macroscopic objects. We analyzed 13 years of tracking data of the LAGEOS satellites with GEODYN II software but with no models for general relativity. From the fit of LAGEOS II pericenter residuals we have been able to obtain a 99.8% agreement with the predictions of Einstein's theory. This result may be considered as a 99.8% measurement in the field of the Earth of the combination of the gamma and beta parameters of general relativity, and it may be used to constrain possible deviations from the inverse-square law in favor of new weak interactions parametrized by a Yukawa-like potential with strength alpha and range lambda. We obtained abs(alpha) 1x10. -11), a huge improvement at a range of about 1 Earth radius.Source: Physical review letters (Print) 105 (2010): 231103-1–231103-4. doi:10.1103/PhysRevLett.105.231103

Ambient Vibrations of Age-old Masonry Towers: Results of Long-term Dynamic Monitoring in theHistoric Centre of Lucca
Azzara R. M., Girardi M., Iafolla V., Lucchesi D. M., Padovani C., Pellegrini D.
The paper presents the results of an ambient vibration monitoring campaign conducted on theso-called "Clock Tower" (Torre delle Ore), one of the best known and most visited monuments inthe historic centre of Lucca. The vibrations of the tower were continuously monitored fromNovember 2017 to March 2018 using high-sensitivity instrumentation. In particular, four seismicstations provided by the Istituto Nazionale di Geofisica e Vulcanologia and two three-axialaccelerometers developed by AGI S.r.l., spin-off of the National Institute for Astrophysics, wereinstalled on the tower. The measured vibration level was generally very low, since the structurelies in the middle of a limited traffic area. Nevertheless, the availability of two different types ofhighly sensitive and accurate instruments allowed the authors to follow the dynamic behaviour ofthe tower during the entire monitoring period and has moreover provided cross-validation of theresults.Source: International journal of architectural heritage 15 (2019): 5–21. doi:10.1080/15583058.2019.1695155

Sounding the atmospheric density at the altitude of Lares and AJISAI during solar cycle 24
Pardini C., Anselmo L., Lucchesi D., Peron R., Bassan M., Magnafico C., Pucacco G., Visco M.
The passive spherical satellites LARES and Ajisai, placed in nearly circular orbits with mean geodetic altitudes between 1450 and 1500 km, were used, during Solar Cycle 24, as powerful tools to probe the neutral atmosphere density and the performances of six thermospheric models in orbital regimes for which the role of dominant atomic species is contended by hydrogen and helium, and accurate satellite measurements are scarce. The starting point of the analysis was the accurate determination of the secular semi-major axis decay rate, leading to the estimation of drag coefficients for each satellite, thermospheric model and solar activity condition. The associated components of the neutral drag acceleration in a satellite-centered orbital system were computed as well. Following the estimation of the physical drag coefficients for LARES and Ajisai, it was then possible to derive the mean density biases of the models. None of them could be considered unconditionally the best, the specific outcome depending on solar activity and on the regions of the atmosphere crossed by the satellites. During solar maximum conditions, an additional density bias linked to the satellite orbit inclination was detected.Source: 32nd International Symposium on Space Technology and Science (ISTS) & 9th Nano-Satellite Symposium (NSAT), Fukui, Japan, June 15-21, 2019

A new general model for the evolution of the spin vector of the two LAGEOS satellites and LARES and the LARASE research program
Lucchesi D. M., Anselmo L., Bassan M., Magnafico C., Pardini C., Peron R., Pucacco G., Stanga R., Visco M.
We present a new general model to calculate the evolution of the spin of passive, conductive and spherical satellites such as the two LAGEOS and LARES. The knowledge of the spin, both in orientation and rate, is of fundamental importance to model correctly the thermal effects on the surface of these satellites, as in the case of the solar Yarkovsky-Schach effect and of the Earth's Thermal drag. These are very important non-gravitational perturbations that produce long-term effects on the orbit of the cited satellites. Therefore, the improvement of the accuracy of the models developed to handle these perturbations represents a very significant result. Such enhancements, with the possibility of a more reliable orbit determination for the satellites, will be very useful in the field of General Relativity measurements with laser-ranged satellites, as well as in the fields of space geodesy and of geophysics.Source: 20th International Workshop on Laser Ranging, Potsdam, Germany, October 9-14, 2016

Relativistic effects and space geodesy with laser ranged satellites: the LARASE research program
Lucchesi D. M., Anselmo L., Bassan M., Magnafico C., Pardini C., Peron R., Pucacco G., Stanga R., Visco M.
LARASE (LAser RAnged Satellites Experiment) aims to provide refined measurements of Einstein's theory of General Relativity by means of the very precise measurements of the Satellite Laser Ranging technique. In this regard, a big effort of LARASE is devoted to improve the dynamical model of the two LAGEOS satellites and of the new satellite LARES. The target is to obtain a more precise and accurate determination of their orbit. Indeed, the systematic error sources due to both the gravitational and non-gravitational perturbations may corrupt the relativistic measurements. At the same time, it is indisputable that a more accurate and precise orbit determination (POD) of the satellites, based on a more reliable dynamical model, represents a fundamental precondition to eventually reach a sub-mm precision in the SLR range residuals and, consequently, to gather benefits in the fields of space geodesy and of geophysics. The results obtained over the last year will be presented in terms of the improvements achieved in the dynamical model, in the satellites POD and, finally, in the measurement of the relativistic Lense-Thirring precession of their orbit.Source: 20th EGU General Assembly, EGU2018, pp. 8340–8340, Vienna, Austria, 4-13/10/2018

LARASE (LAser RAnged Satellites Experiment) aims to provide refined measurements of Einstein's theory of General Relativity by means of the very precise measurements of the Satellite Laser Ranging technique. In this regard, a big effort of LARASE is devoted to improve the dynamical model of the two LAGEOS satellites and of the new satellite LARES. The target is to obtain a more precise and accurate determination of their orbit.

SaToR-G: a new experiment for fundamental physics measurements with laser-ranged satellites
Lucchesi D. M., Anselmo L., Bassan M., Lucente M., Magnafico C., Pardini C., Peron R., Pucacco G., Visco M.
We present a new experiment called SaToR-G (Satellites Tests of Relativistic Gravity) which mainly concerns on verifying the gravitational interaction beyond the predictions of General Relativity, looking for possible effects connected with new physics, and foreseen by different alternative theories of gravitation. SaToR-G exploits the improvement of the dynamical model of the two LAGEOS and of LARES satellites performed within the previous research program called LAser RAnged Satellites Experiment (LARASE: 2013-2019) and funded by the Italian INFN (Istituto Nazionale di Fisica Nucleare). Within LARASE we achieved a new measurement of the Lense-Thirring precession with an accuracy better than 2%. To reach the objectives foreseen by SaToR-G, we need to provide a precise orbit determination of a set of laser-ranged satellites, such as the two LAGEOS, LARES, and the forthcoming LARES-2, whose launch is expected before the end of this year. The state-of-the-art regarding the modelling improvements currently reached with LARASE will be presented together with the main objectives of SaToR-G in the fields of relativistic measurements and space geodesy.Source: 43rd COSPAR Scientific Assembly 2021 (Hybrid), Sydney, Australia, 28/01/2021 - 04/02/2021

A new accurate measurement of the dragging of inertial frames a century after the Einstein, Thirring and Lense papers.
Lucchesi D. M., Anselmo L., Bassan M., Magnafico C., Pardini C., Peron R., Pucacco G., Visco M.
Gravitomagnetism represents one of the most peculiar predictions of Einstein's geometrodynamics and describes the spacetime curvature effects due to mass-currents. Following Einstein, gravitomagnetism is responsible of the so-called dragging of the local inertial frames, whose axes are defined by the orientation of gyroscopes with respect to the distant stars. The orbital plane of an Earth-orbiting satellite is a sort of enormous gyroscope once removed all classical perturbations that arise from the main gravitational and non-gravitational perturbations. We present a new measurement of the dragging effect on the combined orbits of the two LAGEOS satellites with that of LARES, which results in both a precise and accurate measurement of the Earth's gravitomagnetic field, towards an assessment of about a 1% of the main systematic sources of error. This result was achieved by the LARASE experiment under the astroparticle physics experiments of the National Scientific Committee 2 of the INFN.Source: 105° Congresso Nazionale della Società Italiana di Fisica (SIF), L'Aquila, 23-27/09/2019

Relativistic effects measurements in the field of the Earth and the LARASE research program
Lucchesi D. M., Anselmo L., Bassan M., Magnafico C., Pardini C., Peron R., Pucacco G., Stanga R., Visco M.
The main goal of the LARASE (LAser RAnged Satellites Experiment) research program is to obtain refined tests of Einstein's theory of General Relativity by means of very precise laser measurements of the round-trip time from ground stations to a set of geodetic satellites. In particular, a big effort of LARASE is dedicated to improve the dynamical models of the LAGEOS, LAGEOS II and LARES satellites, with the objective to obtain a more precise and accurate determination of their orbit. These activities contribute also to reach a reliable and robust error budget for the main sources of systematic errors. The results reached over the last year will be presented in terms of the improvements achieved in the dynamical model, in the orbit determination and, finally, in the measurement of the relativistic precessions that act on the orbit of the satellites.Source: 103° Congresso Nazionale della Società Italiana di Fisica (SIF), Trento, 11-15/09/2017
