Strong gravitational lensing constraints on interacting dark energy models
F. Villalobos, T. Verdugo, P. Troncoso-Iribarren +2
The possible interaction between dark matter and dark energy has been proposed as a mechanism to alleviate the coincidence problem and the Hubble tension. Strong gravitational lens…
Study of dark interactions through strong gravitational lenses
F. Villalobos, J. Magana, T. Verdugo
The possible interaction between the dark components of the Universe (dark matter and dark energy) stands as an attractive alternative to the standard CDM cosmological model. I…
Reconstructing the cosmic expansion with a generalized q(z) parameterization: A decelerating Universe from late-time constraints
Tomás Verdugo, Alberto Hernández-Almada, Miguel A. GarcÃa-Aspeitia +2
We present a generalized phenomenological parameterization of the deceleration parameter that incorporates an effective radiative component (ERC) in addition to a localized…
GraViT: Transfer Learning with Vision Transformers and MLP-Mixer for Strong Gravitational Lens Discovery
René Parlange, Juan C. Cuevas-Tello, Octavio Valenzuela +4
Gravitational lensing offers a powerful probe into the properties of dark matter and is crucial to infer cosmological parameters. The Legacy Survey of Space and Time (LSST) is pred…
