The cosmic ionizing emissivity from star-forming galaxies has long been anchored to UV luminosity functions. Here, we introduce an emissivity framework based on...

Publication28-40 GHz variability and polarimetry of bright compact sources in the QUIJOTE cosmological fields
We observed 51 sources in the Q-U-I JOint TEnerife (QUIJOTE) cosmological fields that were brighter than 1 Jy at 30 GHz in the Planck Point Source Catalogue...

Publication30 GHz observations of sources in the Very Small Array fields
Small angular scale (high l) studies of cosmic microwave background (CMB) anisotropies require accurate knowledge of the statistical properties of extragalactic...

PublicationA blind detection of a large, complex, Sunyaev-Zel'dovich structure
We present an interesting Sunyaev-Zel’dovich (SZ) detection in the first of the Arcminute Microkelvin Imager (AMI) ‘blind’, degree-square fields to have been...

PublicationA case study of hurdle and generalized additive models in astronomy: the escape of ionizing radiation
The dark ages of the Universe end with the formation of the first generation of stars residing in primeval galaxies. These objects were the first to produce...

PublicationA common explanation of the Hubble tension and anomalous cold spots in the CMB
The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component. Disquietingly, its...

PublicationA conspicuous increase of Galactic contamination over CMBR anisotropies at large angular scales
New calculations of the Galactic contamination over microwave background radiation anisotropies are carried out. On the one hand, when a frequency-dependent...

PublicationA cosmological context for compact massive galaxies
To provide a quantitative cosmological context to ongoing observational work on the formation histories and location of compact massive galaxies, we locate and...

PublicationA different approach to the cosmological quantized redshift problem
A new phenomenological model for the interpretation of the discrete redshift phenomenon is developed. The model, based on the basic physical notion of adiabatic...
