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…
Revisiting the CMB homogeneity scale: low multipoles removal effect and extragalactic foreground masking
Xiaoyun Shao, Facundo Toscano, Diego Garcia Lambas +5
The Cosmic Microwave Background (CMB) reaches homogeneity at relatively modest angular scales compared to the expectation of the standard CDM model revealing an important challe…
Current constraints on the minimally extended varying speed of light model through the cosmic distance duality relation
Jaiane Santos, Carlos Bengaly, Rodrigo S. Gonçalves
One of the most crucial tests of the standard cosmological model consists on testing possible variations on fundamental physical constants. In frameworks such as the minimally exte…
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…
