Non canonical polarizations of Gravitational Waves
Stefano Bondani, Sergio Luigi Cacciatori
We hereby propose an alternative and additional angle on the nature of gravitational waves (GWs), postulating the theoretical and experimental possibility that GWs carry a deformat…
Equatorial Lensing in the Balasin-Grumiller Galaxy Model
Marco Galoppo, Sergio Luigi Cacciatori, Vittorio Gorini +1
The Balasin-Grumiller model has been the first model employed as an attempt towards providing a fully general relativistic description of the dynamics of a disc galaxy. In this pap…
Intersection Numbers in Quantum Mechanics and Field Theory
Sergio L. Cacciatori, Pierpaolo Mastrolia
By elaborating on the recent progress made in the area of Feynman integrals, we apply the intersection theory for twisted de Rham cohomologies to simple integrals involving orthogo…
Re-weighting dark matter in disc galaxies: a new general relativistic observational test
Davide Astesiano, Sergio L. Cacciatori, Massimo Dotti +2
A recent analysis of data from the ESA Gaia mission demonstrated that the kinematics of stars in the Milky Way can be modelled without invoking the presence of dark matter whatsoev…
Macdonald formula, Ricci Curvature, and Concentration Locus for classical compact Lie groups
Sergio L. Cacciatori, Pietro Ursino
For Classical compact Lie groups, we use Macdonald's formula \cite{Ma} and Ricci curvature for analyzing a "concentration locus", which is a tool to detect where a sequence of metr…
Cooking pasta with Lie groups
S. L. Cacciatori, F. Canfora, M. Lagos +2
We extend the (gauged) Skyrme model to the case in which the global isospin group (which usually is taken to be ) is a generic compact connected Lie group . We analyze th…
