    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 dark sectors: experiments involving B meson decays developed at the Large Hadron Collider at CERN and at Belle II in Japan are very sensitive to the presence of new forces interacting with the heavier quarks of the Standard Model. This allows us to explore our understanding of the fundamental laws of physics at the smallest scales at which we have been able to observe. This would have consequences in the Early Universe, such as the existence of flavor-laden dark sectors, the production of topological defects or the introduction of new mechanisms to explain baryogenesis.

      Contribution to the beauty quark decay  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 at observed by the space mission Fermi-LAT or expected to be observed at the Cherenkov Telescope Array (CTA).

    Our group currently consists of 2 Staff (Jorge Martin Camalich and Carlos Hernandez-Monteagudo), 2 postdoc (Christopher Eckner and Luca Teodori) and 6 PhD students (Andrés Bañares, Alba Crespo, Mar Pérez, Fernando Valenciano, Elena Vanetti y Ruben Zatini). Other members of the group include UNDARK's project manager (Claudia Guerrero García-Hera) y scientific communicator (Raquel Conde). Please do not hesitate to contact us at jcamalich at iac.es if you would like to do a PhD with us, work with us or visit our group!
