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…

Quasar cosmology II: joint analyses with Cosmic Microwave Background
M. Benetti, G. Bargiacchi, G. Risaliti +3
Currently, the increasing availability of accurate cosmological probes leads to the emergence of tensions between data on the one hand and between theoretical predictions and direc…
