    Observing the polarized microwave sky: 10 years of the QUIJOTE experiment
    I will review the status of the QUIJOTE (Q-U-I JOint TEnerife) experiment, a project led from the IAC with the aim of characterising the polarisation of the...

    A cut-off in the TeV gamma-ray spectrum of the SNR Cassiopeia A
    It is widely believed that the bulk of the Galactic cosmic rays is accelerated in supernova remnants (SNRs). However, no observational evidence of the presence...

    A hydrodynamical study of outflows in starburst galaxies with different driving mechanisms
    Outflows from starburst galaxies can be driven by thermal pressure, radiation, and cosmic rays. We present an analytic phenomenological model that accounts for...

    An Integral View of Balmer-dominated Shocks in Supernova Remnants
    We present integral-field spectroscopic observations with the VIMOS-IFU at the VLT of fast (2000-3000 kms-1) Balmer-dominated shocks surrounding the...

    Balmer Filaments in Tycho’s Supernova Remnant: An Interplay between Cosmic-ray and Broad-neutral Precursors
    We present Hα spectroscopic observations and detailed modeling of the Balmer filaments in the supernova remnant (SNR) Tycho (SN 1572). We used GH α FaS (Galaxy...

    Beryllium and Boron Evolution in the Galaxy
    We present a model for the evolution of the light-nuclide abundances in the Galaxy, aimed especially at interpreting the observed beryllium and boron abundances...

    Can solar activity and cosmic rays save us from global warming?
    Global warming has often been portrayed as being connected only to greenhouse gasses in widespread media. However, these are just one of many factors...

    Caprichos magnéticos
    Hablaré de tres caprichos. El primero pretende responder a la pregunta: ¿Existen lentes magnéticas en el Cosmos? El segundo trata de un problema de Milagro...

    Constraining Lorentz Invariance Violation Using the Crab Pulsar Emission Observed up to TeV Energies by MAGIC
    Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non...
