Modified Gravity from growth data: goodness-of-fit and gravitational coupling
Manoel V. S. Filho, Fernanda Oliveira, Wiliam S. Hipólito-Ricaldi +2
While background expansion data alone cannot discriminate among cosmological models, the growth of large-scale structures directly probes the underlying theory of gravity, offering…
First tomographic measurements of the angular clustering and bias of photometric quasars from S-PLUS
Maria Lopes, Felipe Avila, Armando Bernui +1
We investigate the quasar clustering in the QuCatS photometric catalog, constructed from the fourth data release of the Southern Photometric Local Universe Survey (S-PLUS). The qua…
Testing Scale-Dependent Suppression of Structure Growth in the Linear Regime
Fernanda Oliveira, Miguel A. Sabogal, Felipe Avila +2
We investigate recent reports of a suppression in the growth rate of cosmic structures inferred from analyses of the dataset. To address this issue, we explore the hypo…
Physics-guided discovery of dynamical dark-energy equations of state through iterative AI reasoning
Clecio R. Bom, Bernardo M. Fraga, Miguel A. Sabogal +3
Phenomenological model building has traditionally relied on human reasoning: equations are proposed from theoretical intuition, analogy, or empirical convenience, and only then tes…
Measuring and BAO scale in the Local Universe: a joint real and redshift space analysis from CosmicFlows-4++
C. Franco, H. M. Courtois, A. Bernui
The large-scale clustering of galaxies encodes both geometric and dynamical information about the Universe. The Baryon Acoustic Oscillations (BAO) phenomenon provides a standard ru…
Homogeneity scale in the local Universe: Model-independent estimate from S-PLUS iDR6 blue galaxies
Camila Franco, Felipe Avila, Armando Bernui +8
We present a model-independent estimate of the angular homogeneity scale in the local Universe by analysing data from the Southern Photometric Local Universe Survey (S-PLUS). Two c…
