Phantom scalar field cosmologies constrained by early cosmic measurements
José Antonio Nájera, Celia Escamilla-Rivera
In this work, we explore new constraints on phantom scalar field cosmologies with a scalar field employing early times catalogues related to CMB measurements, along with the local…

Constraints on logarithmic model using gravitational wave standard sirens
José Antonio Nájera, Carlos Aráoz Alvarado, Celia Escamilla-Rivera
In this paper, we study the constraints on the , symmetric teleparallel model using local measurements and gravitational wave mock standard sirens. Usin…

Comment on: "Questioning the tension via the look-back time"
Celia Escamilla-Rivera, José Antonio Nájera
Recently, it has been proposed that Hubble tension can be addressed in the CDM model if the lookback time approach is considered on the redshift measured. From this interest…
