Measuring Dark Energy with Massive Redshift Surveys
The Baryon Oscillation Spectroscopic Survey (BOSS) is a Stage III dark energy experiment on the Sloan Telescope. For the five years from 2009-2014, we are...
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...
