Webto the small-scale challenges going forward. Observational programs to constrain or discover and characterize the number of truly dark low-mass halos are among the most important, and achievable, goals in this field over then next decade. These efforts will either further verify the ΛCDM paradigm or demand a substantial revision in our WebJun 24, 2016 · In the present paper, we will review the small scale problems of the $\Lambda$CDM model, we will discuss the proposed solutions and to what extent they are able to give us a theory accurately...
Small-Scale Challenges to the 𝚲CDM Paradigm
WebPotential small-scale discrepancies in the picture of galaxy formation painted by the ΛCDM paradigm have led to considerations of modified dark matter models. One such dark matter model that has recently attracted much attention is fuzzy dark matter (FDM) . WebThe ΛCDM model, or concordance cosmology, as it is often called, is a paradigm at its maturity. It is clearly able to describe the universe at large scale, even if some issues remain open, such as the cosmological constant problem, the small-scale problems in galaxy formation, or the unexplained anomalies in the CMB. ΛCDM clearly shows difficulty at … onowu ugonabo nigeria highlife music
