Conformal Killing Gravity: New Constraints from DESI DR2 BAO datasets
Himanshu Chaudhary, Salvatore Capozziello, Carlo Alberto Mantica +3
We investigate a geometric approach referred to as the Conformal Killing Gravity (CKG), in which the dark energy sector emerges naturally from the conformal Killing symmetry of the…
Non conservative conformal Killing gravity: coupling the dark sector with curvature and matter
Salvatore Capozziello, Carlo Alberto Mantica, Luca Guido Molinari
The so called Harada gravity with non conserved energy-momentum tensor is here taken into account. It includes Rastall gravity as a special case. The field equations are written as…
Constraints on cosmological parameters and CMB first acoustic peak in conformal Killing gravity
Salvatore Capozziello, Carlo Alberto Mantica, Luca Guido Molinari +1
In the frame of conformal Killing gravity cosmology, we performed a Bayesian analysis on two different datasets of Baryon Acoustic oscillations (DESI and SDSS DR16), two datasets o…
Note on conserved currents in static Conformal Killing Gravity
Carlo Alberto Mantica, Luca Guido Molinari
Conserved currents are discussed for static Conformal Killing Gravity, with explicit expressions in static spherical symmetry with anisotropic matter fluid or coupled to (non)linea…
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…
