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…

The impact of FRB dispersion measure probability distribution functions on cosmographic estimates
Thais Lemos, Rodrigo Gonçalves, Jailson Alcaniz
Recent cosmological observations have reopened the discussion about the model that best describes the dynamics of the Universe, highlighting the need for cosmological model-indepen…

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…
