Nonlinear steepening of a fast magnetoacoustic wave in the vicinity of a coronal magnetic null point
Yu Zhong, Valery M. Nakariakov, Mariana Cécere +1
The interaction of a fast magnetoacoustic wave with a magnetic null point is studied in the context of the sympathetic flare phenomenon. Attention is paid to steepening the wave ca…

Can wormhole spacetimes in Unimodular Gravity be supported by ordinary matter? A general proof of the exotic matter requirement
Mauricio Cataldo, Norman Cruz, Patricio Salgado
We establish a general no--go theorem demonstrating that all traversable wormhole configurations in Unimodular Gravity necessarily require exotic matter. The proof relies solely on…
