    Globular clusters as a dynamical probe of dark matter
    Gravitational dynamical friction affecting the orbits of globular clusters (GCs) was studied extensively as a possible formation mechanism for nuclear star...

    How to use a cosmological N-body simulation as a theoretical model
    A key problem that we are facing in cosmology nowadays is that we cannot make accurate predictions with our current theoretical models. We have all of the...

    How well does galaxy clustering constrain cosmology?
    On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...

    Hunting for VIPERS red nuggets - traces of the past
    Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...

    Matter-antimatter sourced dark matter
    Cosmological and astrophysical e xperimental data demark a large share of the limits of our knowledge in fundamental physics. I'll review two pieces of evidence...

    Nube, la galaxia casi invisible que desafía el modelo de materia oscura
    Un grupo de astrofísicos liderados por Mireia Montes, investigadora del Instituto de Astrofísica de Canarias (IAC), ha descubierto la galaxia más grande y...

    Open questions and Non-Standard models
    I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...

    Presentation of the book: "Fundamental ideas in Cosmology. Scientific, philosophical and sociological critical perspectives" (IoP Science, 2022)
    Cosmological observations (redshifts, cosmic microwave background radiation, abundance of light elements, formation and evolution of galaxies, large-scale...

    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...
