    The LARES 2 satellite, general relativity and fundamental physics

    LARES 2, successfully launched on July 13, 2022, is a new generation laser-ranged satellite. LARES is an acronym for LAser RElativity Satellite. The first LARES satellite was successfully launched on February ...

    Analysis of the prediction of the 2021 time-evolution of the Covid-19 pandemic in Italy using a Planck’s distribution

    In a previous paper, we studied the time-evolution of the Covid-19 pandemic in Italy during the first wave of 2020 using a number of distribution laws. We concluded that the best distribution law to predict th...

    Satellite Laser-Ranging as a Probe of Fundamental Physics

    Satellite laser-ranging is successfully used in space geodesy, geodynamics and Earth sciences; and to test fundamental physics and specific features of General Relativity. We present a confirmation to approxim...

    An improved test of the general relativistic effect of frame-dragging using the LARES and LAGEOS satellites

    We report the improved test of frame-dragging, an intriguing phenomenon predicted by Einstein’s General Relativity, obtained using 7 years of Satellite Laser Ranging (SLR) data of the satellite LARES (ASI, 201...

    A test of general relativity using the LARES and LAGEOS satellites and a GRACE Earth gravity model

    We present a test of general relativity, the measurement of the Earth’s dragging of inertial frames. Our result is obtained using about 3.5 years of laser-ranged observations of the LARES, LAGEOS, and LAGEOS 2...
