Hubble tension vs two flows
  The Hubble tension is shown to be solvable, without any free parameter,
conceptually and quantitatively, within the approach of modified weak-field
General Relativity involving the cosmological constant $\Lambda$. That approach
enables one to describe in a unified picture both the dynamics of dark matter
containing galaxies and the accelerated expansion of the Universe, thus
defining a {\it local} Hubble constant of a local flow and the {\it global}
one. The data on the dark matter content of peculiar galaxy samples are shown
to be compatible to that unified picture. Future more refined surveys of galaxy
distribution, hierarchical dynamics and flows within the vicinity of the Local
group and the Virgo supercluster can be decisive in revealing the possible
common nature of the dark sector.
