Exploring cosmological constraints on galaxy formation time
Agripino Sousa-Neto, Maria Aldinêz Dantas, Javier E. González +2
The Universe consists of a variety of objects that formed at different epochs, leading to variations in the formation time which represents the time elapsed from the onset of struc…

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…
