Morphological Bias: How Ellipticals and Spirals Trace the Cosmic Web Differently
Paula S. Ferreira, Carlos A. P. Bengaly, Renyue Cen
We present a data-driven measurement of galaxy bias and scale-dependent relative bias for elliptical and spiral galaxies using angular auto- and cross-power spectra from DES and DE…
Where Galaxies Point: First Measurement of the Large-Scale Axial Intrinsic Alignment
Pedro da Silveira Ferreira, Rafael Oliveira Ramos, Paula S. Ferreira +5
We report evidence for large-scale axial intrinsic alignment (LAIA): a coherent axis shared by galaxies and cosmic-web filaments. Applying an orientation-field estimator to Dark En…
Measurements of the Angular Homogeneity Scale from DESI DR1
Mariana Lopes-Dias, Carlos A. P. Bengaly, Xiaoyun Shao +4
The study of the large-scale distribution of galaxies provides essential information for testing the standard cosmological model, namely the CDM paradigm. This scenario is base…
Influence of photometric galaxies redshift distribution in BAO estimation
Paula S. Ferreira, Ribamar R. R. Reis
In the present study, we use the DES Y3 catalog of LRG to incorporate the realistic galaxies' redshift Probability Distribution Function(PDF) into the correlation function cosmolog…
Baryon Acoustic Oscillations in tomographic Angular Density and Redshift Fluctuations
Paula S. Ferreira, Carlos Hernández-Monteagudo, Ribamar R. R. Reis
In this work we examine the baryon acoustic oscillations (BAO) in 2D angular and redshift space , with denoting the redshift difference between two given angular…
Pz Cats: Photometric redshift catalogs based on DES Y3 BAO sample
Paula S. Ferreira, Ribamar R. R. Reis
Over the years, photometric redshift estimation (photo-z) has advanced through various methods. This study evaluates four distinct photo-z estimators-ANNz2, BPZ, ENF, and DNF-using…
