      abstract     = {Magnetic fields in galaxies and galaxy clusters are
                      believed to be the result of the amplification of
                      intergalactic seed fields during the formation of
                      large-scale structures in the universe. However, the origin,
                      strength, and morphology of this intergalactic magnetic
                      field (IGMF) remain unknown. Lower limits on (or indirect
                      detection of) the IGMF can be obtained from observations of
                      high-energy gamma rays from distant blazars. Gamma rays
                      interact with the extragalactic background light to produce
                      electron−positron pairs, which can subsequently initiate
                      electromagnetic cascades. The gamma-ray signature of the
                      cascade depends on the IGMF since it deflects the pairs.
                      Here we report on a new search for this cascade emission
                      using a combined data set from the Fermi Large Area
                      Telescope and the High Energy Stereoscopic System. Using
                      state-of-the-art Monte Carlo predictions for the cascade
                      signal, our results place a lower limit on the IGMF of B >
                      7.1 × 10$^{−16}$ G for a coherence length of 1 Mpc even
                      when blazar duty cycles as short as 10 yr are assumed. This
                      improves on previous lower limits by a factor of 2. For
                      longer duty cycles of 10$^{4}$ (10$^{7}$) yr, IGMF strengths
                      below 1.8 × 10$^{−14}$ G (3.9 × 10$^{−14}$ G) are
                      excluded, which rules out specific models for IGMF
                      generation in the early universe.},
