Incorporating baryon-driven contraction of dark matter halos in rotation curve fits

Pengfei Li, Stacy S. McGaugh, Federico Lelli +2

The condensation of baryons within a dark matter (DM) halo during galaxy formation should result in some contraction of the halo as the combined system settles into equilibrium. We…

The intervelocity of galaxy pairs in $Λ$ CDM -- The observed velocity peak at ~130 km/s is not unique to MOND

Marcel S. Pawlowski, Kosuke Jamie Kanehisa, Salvatore Taibi +1

Observational studies of pairs of galaxies have uncovered that their differential line-of-sight velocities indicate the presence of a peak in their three-dimensional intervelocity…
