    QUIJOTE scientific results: XIX. New constraints on the synchrotron spectral index using a semi-blind component separation method
    We introduce a novel approach to estimate the spectral index, β s, of polarised synchrotron emission, combining the moment expansion of Cosmic Microwave...

    QUIJOTE scientific results: XVIII. New constraints on the polarisation of the anomalous microwave emission in bright Galactic regions: ρ Ophiuchi, Perseus, and W43
    This work focuses on the study of the anomalous microwave emission (AME), an important emission mechanism between 10 and 60 GHz whose polarisation properties...

    Spectral properties of Anomalous Microwave Emission in 144 Galactic clouds
    Anomalous Microwave Emission (AME) is a diffuse microwave component thought to arise from spinning dust grains, though it remains poorly understood. We analyzed...

    The C-Band All-Sky Survey (C-BASS): new constraints on the integrated radio spectrum of M 31
    The Andromeda galaxy (M 31) is our closest neighbouring spiral galaxy, making it an ideal target for studying the physics of the interstellar medium in a galaxy...

    The C-Band All-Sky Survey (C-BASS): Simulated parametric fitting in single pixels in total intensity and polarization
    The cosmic microwave background (CMB) B-mode signal is potentially weaker than the diffuse Galactic foregrounds over most of the sky at any frequency. A common...

    The C-Band All-Sky Survey (C-BASS): template fitting of diffuse galactic microwave emission in the northern sky
    The C-Band All-Sky Survey (C-BASS) has observed the Galaxy at 4.76 GHz with an angular resolution of 0${_{.}^{\circ}}$73 full-width half-maximum, and detected...

    The dark side
    What's the dark matter made of? Do we have any idea of the kind of particle that should constitute ~85% of the matter content of the Universe? In this talk, I...

    The PICASSO map-making code: application to a simulation of the QUIJOTE northern sky survey
    Map-making is an important step for the data analysis of cosmic microwave background (CMB) experiments. It consists of converting the data, which are typically...

    The quest for axions
    We introduce the strong CP problem and the existence of the Axion as a possible solution. We discuss the possibility that axions are the dark matter of the...
