Comment on "Indefinitely Flat Circular Velocities and the Baryonic Tully-Fisher Relation from Weak Lensing"

Abstract

The recent measurements of circular velocity curves from weak lensing of the isolated galaxies lead to a conclusion that the circular velocity curves remain flat well beyond the virial radii of dark matter halos up to 1 Mpc. This is in clear contradiction with the LCDM numerical simulations. We show that the additional cosmic force originating from the geometry of the Universe beyond the Friedmann model increases the circular velocities of the test galactic bodies and avoids a decline of the standard LCDM velocity curves.
