Local observers in stationary axisymmetric dust spacetimes
Matteo Fontana, Sergio Luigi Cacciatori, Roberto Peron
In this work, we construct a locally inertial reference system adapted to a geodesic observer in stationary, axisymmetric dust solutions of the Einstein equations employed as effec…

Asymptotically Conically Minkowskian spacetimes from self-gravitating dust
Matteo Fontana, Federico Scali, Sergio Luigi Cacciatori
In this work we investigate some non-Newtonian effects in exact solutions of the Einstein equations, which describe stationary and axisymmetric configurations of self-gravitating d…

Application of interpretable machine learning for cross-diagnostic inference on the ST40 spherical tokamak
Tadas Pyragius, Cary Colgan, Hazel Lowe +4
Machine learning models are exceptionally effective in capturing complex non-linear relationships of high-dimensional datasets and making accurate predictions. However, their intri…
