Newman Tamburino solutions with an aligned Maxwell field
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 leads to the cylindrical class.Comment: 5 page
Complete integration of the aligned Newman Tamburino Maxwell solutions
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 look at the possible vacuum limits and we examine the
symmetries of the general solution
New results for Petrov type D pure radiation fields
We present a new family of Petrov type D pure radiation spacetimes with a
shear-free, non-diverging geodesic principal null congruence.Comment: 4 pages; changed the appearance of some v's and nu'
