We address recently reported anomalously large bulk flows on scales of 100Mpc/h and beyond. These coherent motions of galaxies challenge the standardLCDM concordance model as well as a large class of competitive models of darkenergy and modified gravity. If confirmed, they may support alternative modelsthat include extra couplings inducing enhanced peculiar velocities on largescales. A complementary probe of the evolution of large-scale perturbations isthe integrated Sachs-Wolfe effect; we explore the connection between thisobservable and the bulk flow. For illustration, we consider a coupling betweendark energy and dark matter as well as a specific cosmological model, growingneutrino quintessence.
