We study plane–fronted electrovacuum waves in metric–affine gravity (MAG) with cosmological constant in the triplet ansatz sector of the theory. Their field strengths are, on the gravitational side, curvature Rα , nonmetricity Qαβ , torsion T α and, on the matter side, the electromagnetic field strength F . Here we basically present, after a short… CONTINUE READING
