Testing Statistical Isotropy in the FRB Sky Distribution: A Selection-Function-Aware Framework
Bruno W. N. Ribeiro, Thais Lemos, Carlos A. P. Bengaly +5
We perform a test of statistical isotropy in the Universe using the sky distribution of fast radio bursts (FRBs), based on a compilation of events detected by multiple surve…
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…
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 based…
On the bin sensitivity of the transverse BAO
Paula S. Ferreira, Carlos A. P. Bengaly
We investigate the transverse BAO projection effect caused by redshift binning uncertainty (). For SKA HI and DESI LRG surveys, we compare Gaussian, top-hat, and semi-Gaussian…
Confirming the uniformity of the Hubble flow with Pantheon+ Supernovae
Xiaoyun Shao, Carlos A. P. Bengaly
According to the perturbed Friedmann model, the difference between Hubble constant measurements in two rest frames, at leading order in velocity, is determined solely by the relati…
Cosmic homogeneity: the effect of redshift-space distortions and bias and cosmological constraints
Xiaoyun Shao, Rodrigo Gonçalves, Carlos A. P. Bengaly +2
We present a novel cosmological analysis based on the angular correlation dimension curve, a cumulative statistic derived from the two-point correlation function. Unlike trad…
