SUMMARY:Cosmology from large-scale structure: concordance and discordance 
 - John Peacock (Edinburgh)

CONTACT:Tobias Baldauf
DESCRIPTION:I will review some recent and forthcoming datasets that aim to
  extract\nfundamental cosmology from the galaxy distribution\, particularl
 y the\nDES and DESI experiments. A particular issue in this field is the\n
 control of systematics\, and I will discuss steps that are taken to\nensur
 e that results of a given experiment are internally consistent.\nBut there
  has been a recent tendency for less than perfect agreement\nbetween diffe
 rent experiments ("tensions")\, indicating either possible\nnew physics or
  undiagnosed systematics. I will discuss a proposal for\nhow the latter ma
 y be allowed for in order to derive conservative\nlimits on cosmological p
 arameters.
