Constraining modified gravity models through strong lensing cosmography
Mario H. Amante, Andrés Lizardo, Javier Chagoya +1
We analyze cosmography as a tool to constrain modified gravity theories. We take four distinct models and obtain their parameters in terms of the cosmographic parameters favored by…
On phenomenological parametrizations for the luminosity distance of gravitational waves
Andrés Lizardo, Javier Chagoya, C. Ortiz
The propagation of gravitational waves offers new possibilities for testing the theory of gravity. Amongst these possibilities there is the luminosity distance of gravitational wav…
Strong lensing by DHOST black holes
Javier Chagoya, C. Ortiz, Benito Rodríguez +1
The deflection of light in the strong field limit is an important test for alternative theories of gravity. However, solutions for the metric that allow for analytic computations a…
