Astroparticle Theory




    Our group works on theoretical astroparticle physics and our goal is to expand our understanding of the fundamental laws of Nature by exploiting the synergies between astrophysical observations and laboratory experiments. Different lines we are currently working on are:

    • Indirect searches of dark matter: New light exotic particles coupled very weakly to the Standard Model (such as the axion or the dark photon) are suitable candidates of dark matter that could manifest through some distinctive signatures in astrophysical observations and laboratory searches. We are currently investigating and developing new strategies to shape observationaly the properties of such type of dark matter including (but not restricted to) stellar cooling of neutron stars and red giants, time series of polarization of pulsar emission and impact of this dark matter on small scale structure. We are also developing new theoretical models of dark matter which could simultaneously address baryogenesis or which could furnish theoretically dark photons.

    • New physics, flavor physics and cosmology: Recent experiments involving decays of bottom-mesons developed at the Large Hadron Collider in CERN have found results which suggest the presence of new muon-specific forces in Nature. Independent hints for such New Physics has also been reported in measurements of the anomalous magnetic moment of the muon. If confirmed, this would imply a discovery transforming our understanding of the fundamental laws of physics at the smallest scales that we have probed. This will have consequences in the Early Universe that we want to explore, such as the production of topological defects, like cosmic strings or magnetic monopoles, the introduction of new mechanisms to explain baryogenesis or the presence of new particles that could constitute dark matter.

      Lepton-Universality violation as measured by LHCb and induced by a super-heavy (m~30 TeV) and exotic particle called the leptoquark.
    • Fundamental Physics in high-energy gamma rays: We are exploring different strategies that could exploit the ultra-high energies of the gamma rays expected to be observed at the Cherenkov Telescope Array (CTA) or the Large High Altitude Air Shower Observatory (LHAASO) to probe aspects of fundamental physics.
