Tolman-Oppenheimer-Volkoff equation and static spheres in Conformal Killing gravity
Carlo Alberto Mantica, Luca Guido Molinari
We derive the analog of the Tolman - Oppenheimer - Volkoff equation in conformal Killing gravity in a static spherically symmetric spacetime, sourced by anisotropic fluid matter. I…
Conformal Killing gravity in static spherically-symmetric spacetimes
Carlo Alberto Mantica, Luca Guido Molinari
We identify an anisotropic divergence-free conformal Killing tensor for static spherically symmetric spacetimes, and write the conformal Killing gravity equations as Einst…
Conformal Killing cosmology -- Geometry, dark sector, growth of structures, and big rip
Carlo Alberto Mantica, Luca Guido Molinari
We introduce Sinyukov-like tensors, a special kind of conformal Killing tensors. In Robertson-Walker space-times they have the perfect-fluid form and only depend on two constants a…
Second Response to the critique of "Cotton Gravity''
R. A. Sussman, C. A. Mantica, L. G. Molinari +1
Clement and Noiucer submitted a note {\tt arXiv:2401.16008 [gr-qc]} replying to our criticism {\tt arXiv:2401.10479 [gr-qc]} of their previous submission. We reply to the contents…
Friedmann equations in the Codazzi parametrization of Cotton and extended theories of gravity and the Dark Sector
Carlo Alberto Mantica, Luca Guido Molinari
The Friedmann equations of Cotton gravity provide a simple parametrization to reproduce, by tuning a single function, the Friedmann equations of several extensions of gravity, such…
Response to a critique of "Cotton Gravity"
Roberto A Sussman, Carlo Alberto Mantica, Luca Guido Molinari +1
We address in this article the criticism in a recently submitted article by Clement and Noiucer (arXiv:2312.17662 [gr-qc]) on "Cotton Gravity" (CG), a gravity theory alternative to…
