Query: Morphology and flow patterns in highly asymmetric active emulsions   We investigate numerically, by a hybrid lattice Boltzmann method, the
morphology and the dynamics of an emulsion made of a polar active gel,
contractile or extensile, and an isotropic passive fluid. We focus on the case
of a highly off-symmetric ratio between the active and passive components. In
absence of any activity we observe an hexatic-ordered droplets phase, with some
defects in the layout. We study how the morphology of the system is affected by
activity both in the contractile and extensile case. In the extensile case a
small amount of activity favors the elimination of defects in the array of
droplets, while at higher activities, first aster-like rotating droplets
appear, and then a disordered pattern occurs. In the contractile case, at
sufficiently high values of activity, elongated structures are formed. Energy
and enstrophy behavior mark the transitions between the different regimes.
