Indefinitely Flat Circular Velocities and the Baryonic Tully-Fisher Relation from Weak Lensing.

MISTELE T., McGAUGH S., LELLI F., SCHOMBERT J. and LI P.

Abstract (from CDS):

We use a new deprojection formula to infer the gravitational potential around isolated galaxies from weak gravitational lensing. The results imply circular velocity curves that remain flat for hundreds of kiloparsecs, greatly extending the classic result from 21 cm observations. Indeed, there is no clear hint of a decline out to 1 Mpc, well beyond the expected virial radii of dark matter halos. Binning the data by mass reveals a correlation with the flat circular speed that closely agrees with the baryonic Tully-Fisher relation known from kinematic data. These results apply to both early- and late-type galaxies, indicating a common universal behavior.
