Inversion maps and torus actions on rational homogeneous varieties
Alberto Franceschini, Luis E. Solá Conde
Complex projective algebraic varieties with -actions can be thought of as geometric counterparts of birational transformations. In this paper we describe geometricall…

Revisiting the evidences for spectral anomalies in distant blazars: new data on the photon-ALP mixing
Francesco Cenedese, Alberto Franceschini, Giorgio Galanti
We re-examine possible dependencies on redshift of the spectral parameters of blazars observed at very-high energies (VHEs) with Imaging Atmospheric Cherenkov telescopes (IACTs). T…
