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
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...
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)...
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...
