SUMMARY:The High-z Cosmic Web in Fuzzy Dark Matter Cosmologies - Tibor Dom

DESCRIPTION:The vanilla Lambda cold dark matter (ΛCDM) model has been so 
 successful that 2018 constraints from the Planck collaboration are based o
 n the variation of the same 6 cosmological parameters as the analysis of t
 he BOOMERanG 1998 data. Yet\, the lack of evidence for any constituent par
 ticle and various small-scale challenges have generated considerable inter
 est in alternative dark matter scenarios such as fuzzy dark matter (FDM). 
 In this talk\, I will discuss how dark matter halo profiles of density and
  shape get modified by FDM’s power spectrum cutoff. They reflect the bro
 ken hierarchy of structure formation which may have observable consequence
 s. The focus of the talk will lie on the high-redshift Cosmic Web in which
  dark matter signatures are more pristine than in today’s Universe.
