The next decade will see a deluge of new cosmological data that will enable us to accurately map out the distribution of matter in the local Universe, image...

After introducing the concepts of axions and axion-like-particles (ALPs) and their signals, true axions which can be either much heavier or muchlighter than the...

I present the recent results obtained using the updated version of MG-MAMPOSSt, a code that constrains modified gravity (MG) models viable at cosmological...

Bosonic ultra-light dark matter (ULDM) in the mass range m ~ $10^{-22} - 10^{-21} \rm eV$ has been invoked as a motivated candidate with new input for the small...

In the first part of this talk I will present a historical review of the CMB observations, one of the most powerful cosmological probes. Following the first...

The standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...

The distribution of matter in galaxies of different luminosities and Hubble types, as inferred from observations, plays an important role in cosmology...
