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…
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…
Cosmological-model independent limits on photon mass from FRB and SNe data
Thais Lemos, Rodrigo Gonçalves, Joel Carvalho +1
Electromagnetic emissions from astrophysical sources at cosmological distances can be used to estimate the photon mass, . In this paper, we combine measurements of the dispers…
Cosmological constraints from angular homogeneity scale measurements
Xiaoyun Shao, Carlos A. P. Bengaly, Rodrigo S. Gonçalves +2
In this paper, we obtain new measurements of the angular homogeneity scale () from the BOSS DR12 and eBOSS DR16 catalogs of Luminous Red Galaxies of the Sloan Digital Sky Surv…
A search for the fine-structure constant evolution from fast radio bursts and type Ia supernovae data
Thais Lemos, Rodrigo Gonçalves, Joel Carvalho +1
The search for a space-time variation of the fundamental constants has been explored over the years to test our physical theories. In this paper, we use the dispersion measure ($DM…
Cosmology and fundamental physics with the ELT-ANDES spectrograph
C. J. A. P. Martins, R. Cooke, J. Liske +20
State-of-the-art 19th century spectroscopy led to the discovery of quantum mechanics, and 20th century spectroscopy led to the confirmation of quantum electrodynamics. State-of-the…
Can the angular scale of cosmic homogeneity be used as a cosmological test?
Xiaoyun Shao, Rodrigo S. Gonçalves, Carlos A. P. Bengaly +3
In standard cosmology, the cosmic homogeneity scale is the transition scale above which the patterns arising from non-uniformities -- such as groups and clusters of galaxies, voids…
Forecasting constraints on the baryon mass fraction in the IGM from fast radio bursts and type Ia supernovae
Thais Lemos, Rodrigo S. Gonçalves, Joel C. Carvalho +1
Fast Radio Bursts (FRBs) are millisecond transient radio events with a high energy. By identifying the origin of the \textbf{burst}, it is possible to measure the redshift of the h…
