    From our understanding, supermassive black holes are the heaviest punctual objects in the universe. However, because of their condition, they are reluctant to be properly weighted and our last generation scales are still very inaccurate. In this talk, I contextualize the importance of properly weighing them and present our latest efforts oriented to characterize and calibrate the weighing...

  10. 9. The Z5 model of two-component dark matter
    Oscar Zapata (Universidad de Antioquia)
    14/12/2020, 16:50

    In this talk we present the phenomenology of the Z5 model for two-component dark matter. This model, which can be seen as an extension of the well-known singlet scalar model, features two complex scalar fields--the dark matter particles--that are Standard Model singlets but have different charges under a Z5 symmetry. The interactions allowed by the Z5 give rise to novel processes between the...

  11. 10. La Materia Oscura en los Tiempos de los Agujeros Negros Primordiales

    Hawking evaporation of primordial black holes (PBH) with masses ranging from ∼10^-1 to ∼10^9 g can generate the whole observed dark matter (DM) relic density. However, a second DM production mechanism, like freeze-out or freeze-in, could have also been active in the early universe. Here we study the interplay of these mechanisms, focusing on the scenario where PBHs dominate the energy density...
