Bright & Dark Universe presentations and interviews

In the last decades, thanks to space telescopes and 4m/8m ground-based telescopes, as well as large digital sky surveys, we have collected large datasets which enabled us to set stringent constraints on the distribution of Dark Matter (DM) at different scales, from dwarfs to spirals and giant ellipticals, from clusters of galaxies to large scale structures and cosmological filaments. Supercomputers showed us how the DM is distributed and how it did drive the evolution and assembly of the luminous matter.

Unfortunately, the match of the observations and theoretical predictions is still inconclusive on scales smaller than the Mpc and this is seriously questioning the overall paradigm. The standing discrepancies can be tracked to missing physics in simulations, or on internal systematics of the models which are leaving the combination of different probes (e.g., stellar/gas kinematics, discrete tracers, strong and weak lensing, X-rays) still highly unexploited.

  1. -Are dark haloes cuspy or cored?

  2. -Are their central density slopes changing with the galaxy type and mass?

- Do dark haloes show concentrations as predicted dark matter simulations?

- Do strong and weak lensing agree with measurement from X-rays?

  1. -What are the constraints on dark matter haloes from individual galaxies?

  2. -And from groups and clusters of galaxies?

  3. -Is the DM cold or warm? Or self-interacting?

  4. -What is the effect of baryon feedback on the DM halo distribution?

  5. -Is there room for extended theories of gravity?

- What are the constraints on the DE and its effect on DM on galactic scales?

- What are the perspectives for the ext facilities from ground and space for the Dark sector of the Universe?

These are the questions we expect to address to prepare the observational challenges of the next generation space missions and extremely large ground-based telescopes and discuss whether the DM is yet a viable paradigm to interpret observations.
