Are Dynamical Dark-Energy Cosmologies Old Enough?
Agripino Sousa-Neto, Susana J. Landau, Jailson Alcaniz
Recent analysis combining baryon acoustic oscillation measurements with cosmic microwave background and Type Ia supernova data show an apparent preference for a time-dependent dark…
A model-independent assessment of the late-time dark energy density evolution
Rayff de Souza, Agripino Sousa-Neto, Javier E. González +1
Combined measurements of Baryon Acoustic Oscillations (BAO) from the Dark Energy Spectroscopic Survey (DESI), the Cosmic Microwave Background (CMB) and Type Ia Supernovae (SN Ia),…
Exploring cosmological constraints on galaxy formation time
Agripino Sousa-Neto, Maria Aldinêz Dantas, Javier E. González +2
The Universe consists of a variety of objects that formed at different epochs, leading to variations in the formation time which represents the time elapsed from the onset of struc…
Reconstructing Cosmic History with Machine Learning: A Study Using CART, MLPR, and SVR
Agripino Sousa-Neto, Maria Aldinez Dantas
In this work, we reconstruct cosmic history via supervised learning through three methods: Classification and Regression Trees (CART), Multi-layer Perceptron Regressor (MLPR), and…
Evidence for dynamical dark energy from DESI-DR2 and SN data? A symbolic regression analysis
Agripino Sousa-Neto, Carlos Bengaly, Javier E. Gonzalez +1
Recent measurements of Baryon Acoustic Oscillations (BAO) from the Dark Energy Spectroscopic Survey (DESI DR2), combined with data from the cosmic microwave background (CMB) and Ty…
