By natural extension, there should be a population of Intermediate-Mass Black Holes (IMBHs: with mass between 100 to 10<SUP>6</SUP>M<SUB>☉</SUB>) in the Universe; which has started to been observed. An exciting claim has been made recently by Silk (2017): that early feedback by IMBHs in gas-rich dwarf galaxies at z = 5-8, can potentially solve multiple dwarf galaxy problems within the Λ-cold-dark-matter cosmology. We are performing Cosmological Hydrodynamical Simulations of (2Mpc)<SUP>3</SUP> volumes, starting from z = 100, to test the case for IMBHs in Dwarf Galaxies. Black holes of mass 1000M<SUB>☉</SUB> are seeded inside halos when they reach a mass of 10<SUP>7</SUP>M<SUB>☉</SUB>. The black holes grow by accretion of gas from their surroundings and by merger with other black holes, and consequently eject feedback energy. We analyze the simulation output in post-processing to study the growth of the first IMBHs, and their impact on star-formation. Our conclusions, based on numerical simulation results, support the phenomenological ideas made by Silk (2017). IMBHs at the centers of dwarf galaxies can be a strong source of feedback to quench star-formation and generate outflows. At the same time, these IMBHs form the missing link between stellar-mass and supermassive BHs....STAMPAenConference paper10.1017/S17439213180055252-s2.0-85083306189https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/intermediatemass-black-hole-feedback-in-dwarf-galaxies-a-view-from-cosmological-simulations/4A116395127B51CB86AA24B20F19C043http://arxiv.org/abs/1811.06576v12020IAUS..342..154BFIS/05 - ASTRONOMIA E ASTROFISICA
