PublicaciónThe Hubble diagram of type Ia supernovae as a function of host galaxy morphology
We present new results on the Hubble diagram of distant type Ia supernovae (SNeIa) segregated according to the type of host galaxy. This makes it possible to...

PublicaciónThe Hubble tension survey: A statistical analysis of the 2012-2022 measurements
In order to investigate the potential Hubble tension, we compile a catalogue of 216 measurements of the Hubble-Lemaître constant H 0 between 2012 and 2022...

PublicaciónThe primordial Helium abundance
The primordial abundance of 4He, YP, is one of the hottest themes in present-day astronomy, mostly due to its cosmological relevance. The disagreement between...

PublicaciónThe statistics of voids as a tool to constrain cosmological parameters: σ8 and Γ
We present a general analytical formalism to calculate accurately several statistics related to underdense regions in the Universe. The statistics are computed...

PublicaciónWMAP 5-year constraints on α and me
We have studied the role of fundamental constants in an updated recombination scenario. We focus on the time variation of the fine structure constant α, and the...
