"Probes of standard and non-standard cosmology"

The large scale  peculiar  motions (deviations from a pure Hubble flow) of  galaxies are our only probe of the 

three-dimensional distribution of the dark matter on large scales. Implications of the observed motions 

in the late-time Universe will be discussed, with emphasis  on some long term challenges arising from the nature of these observations. 

The talk will include a discussion of generic predictions of dark sector modifications to GR for the large scale structure as well as 

the dynamics of galactic satellites.
