Cosmological Constraints on Interacting Scalar-Field Dark Matter and Early Dark Energy mediated by a Kinetic Kernel
Gabriela Garcia-Arroyo, L. Arturo Ureña-López, J. Alberto Vázquez
In this work, we build a general framework for constraining interacting scalar fields with cosmological observations, applicable to a broad family of scalar--field potentials and i…
DESI 2024 VI: Cosmological Constraints from the Measurements of Baryon Acoustic Oscillations
DESI Collaboration, A. G. Adame, J. Aguilar +200
We present cosmological results from the measurement of baryon acoustic oscillations (BAO) in galaxy, quasar and Lyman- forest tracers from the first year of observations from t…
Interacting Scalar fields: Dark matter and early dark energy
Gabriela Garcia-Arroyo, L. Arturo Ureña-López, J. Alberto Vázquez
The main aim of this work is to explore the possibility that cold dark matter (CDM) and early dark energy (EDE) can be described by canonical scalar fields that are coupled at the…
Tracker behaviour of quintom dark energy and the Hubble tension
Nandan Roy, L Arturo Ureña-López
We study the dynamics of the quintom dark energy model using state-of-the-art cosmological observations. The set of equations has been converted into an autonomous system using sui…
Short Review of the main achievements of the Scalar Field, Fuzzy, Ultralight, Wave, BEC Dark Matter model
Tonatiuh Matos, Luis A. Ureña-López, Jae-Weon Lee
The Scalar Field Dark Matter model has been known in various ways throughout its history; Fuzzy, BEC, Wave, Ultralight, Axion-like Dark Matter, etc. All of them consist in proposin…
