PublicaciónObservational Evidence for a Galaxy Overdensity/Protocluster at z=6.5
We present the results of our search near the end of the Reionization Epoch for faint galaxies around two close, massive Lyman-α emitters (LAEs) at redshift 6.5...

CharlaOpen questions and Non-Standard models
I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...

CharlaOrigin of space and time in a non-commutative cosmological model
A Friedman-like cosmological model, based on noncommutative geometry, is presented. Its Planck level is totally nonlocal with no space and no time. The dynamics...

CharlaPast, present and future of cosmic microwave background observations: implications for cosmology
Since its discovery in 1964, the cosmic microwave background (CMB) has been one of the basic pillars of the cosmological model. However, it is only very...

PublicaciónPhysical Properties of a Coma-analog Protocluster at z = 6.5
We present evidence for the discovery of a protocluster of starburst galaxies (Lyα emitters, or LAEs) near the end of the epoch of reionization. The recent...

PublicaciónPISN-explorer: hunting the descendants of very massive first stars
The very massive first stars (m > 100 $\rm M_{\odot }$) were fundamental to the early phases of reionization, metal enrichment, and supermassive black hole...
