    Ameek Malhotra
    21/07/2025, 17:40

    Cosmological model selection, in the framework of Bayesian
    inference requires the calculation of the Bayesian evidence. This can often
    be quite challenging, especially if the underlying likelihood function is
    expensive to evaluate. I will discuss how a technique called Bayesian
    Optimisation, based on Gaussian Process regression, can be used to
    calculate this evidence in far fewer...

    Agnese Tolino
    22/07/2025, 16:20

    Light primordial black holes (PBHs) may have originated in the early Universe, and could contribute to the dark matter in the Universe.
    Their Hawking evaporation into particles could eventually lead to the production of antinuclei, which
    propagate and arrive at Earth as cosmic rays with a flux peaked at GeV energies.
    We revisit here the antiproton and antideuteron signatures from PBH...

    Benjamin Muntz
    24/07/2025, 16:40

    End-of-the-World branes are codimension-one hypersurfaces that mark the ending of spacetime. Interestingly, these have been argued to be necessary ingredients in quantum gravity to prevent the presence of global symmetries. Can they also serve as braneworlds? (Spoiler: Yes.) Motivated by the Swampland Programme and in particular the Cobordism Conjecture, we propose a scenario in which a...

  17. 172. The Hubble Tension and Primordial Magnetic Fields
    Levon Pogosian
    24/07/2025, 17:00

    The Hubble tension hints at a missing ingredient in the standard cosmological model describing the universe around the epoch of recombination. A stochastic magnetic field, if present in the plasma prior to last scattering, would induce baryon inhomogeneities and speed up the recombination process, reducing the sound horizon at last scattering and potentially helping to relieve the Hubble...

  19. 174. The Shape of Space in Polarized Light
    Mikel Martin Barandiaran
    24/07/2025, 17:40

    While the standard cosmological model assumes a flat, simply-connected, infinite universe, the possibility of having a non-trivial spatial topology is still a viable scenario that is potentially detectable in the not so distant future. For the past few decades, the cosmic topology community has almost exclusively focused on scalar-sourced temperature correlations in the cosmic microwave...
