The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component. Disquietingly, its...
I revisit the claim of Dark Energy detection after stacking CMB data on the angular position of voids and superclusters in Sloan Data. I examine the...
In the first part of this talk I will present a historical review of the CMB observations, one of the most powerful cosmological probes. Following the first...
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with...
We describe our non-linear emulation (i.e. interpolation) framework that combines the halo occupation distribution (HOD) galaxy bias model with N-body...
I will discuss how the acoustic oscillations that propagate in the photon-baryon fluid during the first million years of the Universe provide a robust method...
The new instrument, the result of an international collaboration of almost a hundred institutions, including the Instituto de Astrofísica de Canarias, has made...
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...
The evidence for the existence of dark energy is conclusive, but its nature remains one of the most puzzling mysteries in all of physics. Astronomical surveys...
