Kerr-Schild transformation of the Benenti-Francaviglia metric
Masato Nozawa, Takashi Torii
The Benenti-Francaviglia (BF) family of metrics provides the most general form of a spacetime metric that admits two mutually commuting Killing vectors and an irreducible Killing t…

Supersymmetry of the Robinson-Trautman solution
Masato Nozawa
The Robinson-Trautman solution in the Einstein-Maxwell- system admits a shear-free and twist-free null geodesic congruence with a nonvanishing expansion. Restricting to the case…

Robinson-Trautman solutions with scalar hair and Ricci flow
Masato Nozawa, Takashi Torii
The vacuum Robinson-Trautman solution admits a shear-free and twist-free null geodesic congruence with a nonvanishing expansion. We perform a comprehensive classification of soluti…
