Exact pp-wave solutions in shift-symmetric higher-order scalar-tensor theories
Masato Minamitsuji
We investigate exact plane-fronted gravitational wave (pp-wave) solutions within the framework of shift-symmetric quadratic-order higher-order scalar--tensor (HOST) theories. These…

Stealth black hole solutions in higher-order Maxwell-Einstein theories
Masato Minamitsuji
We study static and spherically symmetric black hole solutions in higher-order Maxwell-Einstein theories. We do not particularly focus on the degenerate classes of theories. For se…
