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 disper…

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…
