Generalized Vaidya Spacetime in Cotton and Conformal Killing Theories
Metin Gürses, Yaghoub Heydarzade, Ãetin Åentürk
We demonstrate that the non-vacuum field equations of Cotton gravity and Conformal Killing gravity admit a generalized class of Vaidya-type solutions. In particular, beyond the sta…

Wave Metrics in the Cotton and Conformal Killing Gravity Theories
Metin Gürses, Yaghoub Heydarzade, Ãetin Åentürk
We study wave metrics in the context of Cotton Gravity and Conformal Killing Gravity. First, we consider pp-wave metrics with flat and non-flat wave surfaces and show that they are…

Minimal Einstein-Aether Theory
Metin Gurses, Cetin Senturk, Bayram Tekin
We show that there is a phenomenologically and theoretically consistent limit of the generic Einstein-Aether theory in which the Einstein-Aether field equations reduce to Einstein…
