A new class of non-aligned Einstein-Maxwell solutions with a geodesic, shearfree and non-expanding multiple Debever-Penrose vector
Norbert Van den Bergh
In a recent study [NVdB2017] of algebraically special Einstein-Maxwell fields it was shown that, for non-zero cosmological constant, non-aligned solutions cannot have a geodesic an…
Rotating and twisting locally rotationally symmetric imperfect fluids
Norbert Van den Bergh
Rotating and twisting locally rotationally symmetric imperfect fluids in general relativity admit a much larger set of solutions than the self-similar ones recently suggested in th…
Rotating solenoidal perfect fluids of Petrov type D
Norbert Van den Bergh, Lode Wylleman
We prove that aligned Petrov type D perfect fluids for which the vorticity vector is not orthogonal to the plane of repeated principal null directions and for which the magnetic pa…
Complete integration of the aligned Newman Tamburino Maxwell solutions
Liselotte De Groote, Norbert Van den Bergh
We investigate the cylindrical class of Newman Tamburino equations in the presence of an aligned Maxwell field. After obtaining a complete integration of the field equations we loo…
Newman Tamburino solutions with an aligned Maxwell field
Liselotte De Groote, Norbert Van den Bergh
We prove that there exists no aligned Einstein Maxwell generalization of the spherical class of Newman Tamburino solutions. The presence of an aligned Maxwell field automatically l…
Shearfree perfect fluids with solenoidal magnetic curvature and a gamma-law equation of state
Norbert Van den Bergh, John Carminati, Hamid Reza Karimian
We show that shearfree perfect fluids obeying an equation of state p=(gamma -1) mu are non-rotating or non-expanding under the assumption that the spatial divergence of the magneti…
