PublicationAngular Size Test on the Expansion of the Universe
Assuming the standard cosmological model to be correct, the average linear size of the galaxies with the same luminosity is six times smaller at z = 3.2 than at...

PublicationChallenging a Newtonian prediction through Gaia wide binaries
Under Newtonian dynamics, the relative motion of the components of a binary star should follow a Keplerian scaling with separation. Once orientation effects and...

PublicationCosmological test with the QSO Hubble diagram
A Hubble diagram (HD) has recently been constructed in the redshift range 0 ≲ z ≲ 6.5 using a nonlinear relation between the ultraviolet (UV) and X-ray...

PublicationElectromagnetic Dark Energy
We introduce a new model for dark energy in the Universe in which a small cosmological constant is generated by ordinary electromagnetic vacuum energy. The...

PublicationFitting of supernovae without dark energy
With data from Pantheon, we have at our disposal a sample of more than a 1000 supernovae Ia covering a wide range of redshifts with good precision. Here, we...

PublicationJeans Mass of Newtonian Bose Clouds
The gravitational instability of free and dilute Newtonian boson clouds has been examined. For collisionless Newtonian boson clouds with a uniform unperturbated...

PublicationModel selection using baryon acoustic oscillations in the final SDSS-IV release
The baryon acoustic oscillation (BAO) peak, seen in the cosmic matter distribution at redshifts up to ∼3.5, reflects the continued expansion of the sonic...

PublicationPeaks in the CMBR Power Spectrum II: Physical Interpretation for any Cosmological Scenario
In a previous paper (part I), the mathematical properties of the cosmic microwave background radiation (CMBR) power spectrum which presents oscillations were...
