There is yet no complete proof that these metrics are universal in the presence of matter fields such as electromagnetic and/or scalar fields. In order to get some insight into what happens when we extend the “universality theorem” to the case in which the electromagnetic field is present, as a first step, we study the KSK class of metrics in the context of modified Horndeski theories with Maxwell’s field. We obtain exact solutions of these theories representing the pp-waves and AdS-plane waves in arbitrary D dimensions.Publication A Modified Gravity Theory: Null Aether(IOP Publishing, 2019-03) Metin Gürses; Çetin Şentürk; Şentürk, ÇetinPublication NAT black holes(Springer Science and Business Media LLC, 2019-11) Metin Gürses; Yaghoub Heydarzade; Çetin Şentürk; Şentürk, ÇetinAbstractWe study some physical properties of black holes in Null Aether Theory (NAT) – a vector-tensor theory of gravity. We first review the black hole solutions in NAT and then derive the first law of black hole thermodynamics. The temperature of the black holes depends on both the mass and the NAT “charge” of the black holes. The extreme cases where the temperature vanishes resemble the extreme Reissner–Nordström black holes. We also discuss the contribution of the NAT charge to the geodesics of massive and massless particles around the NAT black holes.Publication Kerr-Schild-Kundt metrics in generic Einstein-Maxwell theories(American Physical Society (APS), 2022-02-03) Metin Gürses; Yaghoub Heydarzade; Çetin Şentürk; Şentürk, Çetin; Şentürk, Çetin; Şentürk, Çetin
