Coupling between relativistic jets launched by accreting supermassive black holes and the surrounding gaseous media is a vital ingredient in galaxy evolution models. To constrain the environments in which this feedback takes place over cosmic time, we study the host-halo properties of luminous low-frequency radio galaxies (L_150 MHz_ ≳ 10^25.25 W Hz^–1) selected with the International Low-Frequency Array Telescope out to z ∼ 2 through tomographic clustering and cosmic microwave background lensing measurements. We find that these systems occupy halos characteristic of galaxy groups (M_h = 10¹³-10¹⁴h^–1_^M_⊙), evolving at a rate consistent with the mean growth rate of halos over the past ∼10 Gyr. The coevolution of the clustering and the luminosity function reveals that the duty cycle of these systems is of order ∼10% but has been mildly increasing since z ∼ 2, while the duty cycle of quasars has been declining. We estimate the characteristic kinetic heating power injected by powerful jets per halo as a function of mass, and compare to the same quantity injected by quasar winds. We find that powerful jet heating dominates over quasar winds in halos M_h ≳ 10¹³_^h^–1_^M_⊙ at z < 2. These results conform to the paradigm of galaxy evolution in which mechanical jet power feedback is the dominant heating mechanism of the gas content of groups and clusters.
