      abstract     = {The conformational and rheological properties of active
                      filaments/polymers exposed to shear flow are studied
                      analytically. Using the continuous Gaussian semiflexible
                      polymer model extended by the activity, we derive analytical
                      expressions for the dependence of the deformation,
                      orientation, relaxation times, and viscosity on the
                      persistence length, shear rate, and activity. The model
                      yields a Weissenberg-number dependent shear-induced
                      deformation, alignment, and shear thinning behavior,
                      similarly to the passive counterpart. Thereby, the model
                      shows an intimate coupling between activity and shear flow.
                      As a consequence, activity enhances the shear-induced
                      polymer deformation for flexible polymers. For semiflexible
                      polymers/filaments, a nonmonotonic deformation is obtained
                      because of the activity-induced shrinkage at moderate and
                      swelling at large activities. Independent of stiffness,
                      activity-induced swelling facilitates and enhances alignment
                      and shear thinning compared to a passive polymer. In the
                      asymptotic limit of large activities, a polymer length- and
                      stiffness-independent behavior is obtained, with universal
                      shear-rate dependencies for the conformations, dynamics, and
                      rheology},
