DESI constraints on -attractor inflationary models
George Alestas, Marienza Caldarola, Sachiko Kuroyanagi +1
The recent results on the baryon acoustic oscillations measurements from the DESI collaboration have shown tantalizing hints for a time-evolving dark energy equation of state param…
To curve, or not to curve: Is curvature-assisted quintessence observationally viable?
George Alestas, Matilda Delgado, Ignacio Ruiz +3
Single-field models of accelerated expansion with nearly flat potentials, despite being able to provide observationally viable explanations for the early-time cosmic inflation and…
Enhancing Cosmological Model Selection with Interpretable Machine Learning
Indira Ocampo, George Alestas, Savvas Nesseris +1
We propose a novel approach using neural networks (NNs) to differentiate between cosmological models, and implemented LIME as an interpretability approach to identify the key featu…
Euclid. I. Overview of the Euclid mission
Euclid Collaboration, Y. Mellier, Abdurro'uf +1134
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…
Applying the Viterbi Algorithm to Planetary-Mass Black Hole Searches
George Alestas, Gonzalo Morras, Takahiro S. Yamamoto +3
The search for subsolar mass primordial black holes (PBHs) poses a challenging problem due to the low signal-to-noise ratio, extended signal duration, and computational cost demand…
