42. A conclusive test of the cold dark matter model

CARLOS,SILVESTRE FRENK

9/1/23, 9:15 AM

34. Unraveling Inconsistencies in the Standard LCDM Model

Eleonora Di Valentino (University of Sheffield)

9/1/23, 10:20 AM

The standard Lambda Cold Dark Matter cosmological model has been incredibly successful in explaining a wide range of observational data, from the cosmic microwave background radiation to the large-scale structure of the universe. However, recent observations have revealed a number of inconsistencies among the model's key cosmological parameters, which have different levels of statistical...

17. Self-Interacting Dark Matter

Hai-Bo Yu (University of California Riverside)

9/1/23, 11:20 AM

I will discuss recent progress on self-interacting dark matter and its implications within the context of the latest observations of galactic systems, as well as high-resolution N-body simulations of cosmic structure formation. I will highlight the novel signatures of gravothermal collapse in dark matter halos, which represent a unique prediction if dark matter possesses strong self-interactions.

20. WDM, sterile neutrino DM

Alexey Boyarsky (Leiden University (NL))

9/1/23, 11:50 AM

35. What quasars can tell us on the accelerating Universe

Elisabeta Lusso

9/1/23, 12:20 PM

I will review what the perspectives of quasars in the context of observational cosmology are and I will present recent measurements of the expansion rate of the Universe based on a Hubble diagram of quasars detected up to the highest redshift ever observed (z~7.5). A deviation from the ΛCDM model emerges at higher redshift, with a statistical significance of ~4σ. If an evolution of the dark...

39. The SKA project: the promises of next-generation radio surveys

Isabella Prandoni

9/1/23, 12:50 PM

I will give an update on the SKA project, its current status and future steps, as well as an overview of its expected scientific capabilities, with a special focus on cosmology-driven radio surveys.
