Observational cosmology at mm wavelengths with KIDs: the NIKA/NIKA2 example
Next generation of CMB experiments will require a large number of detectors (few tens of thousands) in order to tackle the challenging detection of primordial...
On the extreme properties of massive galaxies at high redshifts
Massive (≥ 10 11 M⊙) galaxies at high redshift (z ≥ 1.5) remain mysterious objects. Their extremely small sizes (effective radii of 1-2 kpc) make them...
I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...
Optical Follow-up of Planck SZ sources from the Canary Islands observatories
Planck satellite provides for the first time the possibility to detect galaxy clusters using their Sunyaev-Zeldovich (SZ) effect signature covering the full sky...
Origin of space and time in a non-commutative cosmological model
The amount of baryons seen in the local Universe falls short by a factor2-5 if compared to the amount of detected baryons at intermediate (z~2)or high (z~1,100)...
Origin 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...
Past, 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...
