Testing New Physics with Neutrinos at Dark Matter Experiments ¶
Abstract: In this talk, I will present a new avenue of how to test new physics with neutrinos - the observation of (solar) neutrino scattering in dark matter direct detection experiments. It will be the first time cohere…
Magnetic Fields Across the Universe: From Primordial Physics to the Cosmic Web ¶
Abstract: Recent astronomical observations have revealed that magnetic fields permeate not only galaxies and clusters, but also the voids and filaments of the cosmic web. The origin of these large-scale magnetic fields r…
Bayesian tools for the LHC: a proof of concept in di-Higgs searches ¶
Abstract: Extracting reliable information from collider data requires a combination of mathematical, computational and statistical tools to model the observed distributions, often with the help of powerful simulations. B…
New (astro)physics in high-energy astronomy and cosmology ¶
Abstract: In the first of the talk I will discuss the phenomenology of cosmic-ray diffusion in the Galaxy and the associated gamma-ray and neutrino emission. The aim is to understand how the combined study of local cosmi…
Higgs fine-tuning problems as hint at new physics ¶
Abstract: Since the discovery of the Higgs at the LHC, particle physics model building has been confronted with a severe conceptual challenge: the inferred values of the Higgs’ mass and self-coupling both appear to be fi…
[extra] The interplay between AGN and gas in galaxies ¶
Abstract: Active galactic nuclei (AGN) drive powerful, multiphase outflows into their host galaxies which are expected to play a key role in galaxy evolution. However, exactly how small-scale accretion disc winds couple…
Unveiling the origins of the most energetic particles in the Universe ¶
Abstract: The origins of the most energetic particles in the Universe have been a long-standing puzzle. In the quest to identify their sources, it is crucial to understand how these particles are accelerated, how they es…
[extra -- informal] Recent updates on the AGORA and 300-project within the CROCODILE simulation framework ¶
Abstract: I will update on our progress on the AGORA and Three-Hundred projects within the CROCODILE simulation framework using GADGET4-OSAKA. I will highlight following four recent works on high-z galaxies (Kim et al.;…
Shedding light below the Higgs: searches for low mass resonances in ATLAS ¶
Abstract: The discovery of the Higgs boson added a fundamental piece to the Standard Model, but it also opened new questions about the nature of electroweak symmetry breaking and possible connections to hidden sectors. A…
Quantum simulation of quantum field theories ¶
Abstract: It might seem that mainstream in Quantum Computing nowadays is completely focused on beating classical computers -quantum supremacy- in tasks with -quantum utility- or without practical applications. However, i…
[extra] Krypton nuclei as drivers of the new asymmetric fission island in the subactinide region ¶
Abstract: Fission is the nuclear process by which a nucleus splits into fragments. Although this reaction was discovered nearly 90 years ago, it remains a major fundamental challenge, both experimentally, as data are dif…
A Cosmic Warehouse for Astrophysics: What can we learn from Galaxy Clusters? ¶
Abstract: Galaxy clusters are the end products of the hierarchical formation of structures in the universe in the ΛCDM paradigm. Despite their great masses, clusters are relatively young systems -- some of which are viri…
Strings without supersymmetry ¶
Abstract: String theory provides a consistent microscopic framework for gravity and the other fundamental interactions. However, the string-derived models that we understand best differ from our universe in a key aspect:…
Gravitational particle production and leptogenesis ¶
Abstract: In a curved spacetime, the definition of particles depends on the observer's frame of reference. Consequently, in non-stationary spacetimes, such as those present in the Early Universe during and after inflatio…
[extra] Structure and dynamics of the local group galaxies ¶
Abstract: As the expansion of the universe continues to accelerate, the internal secular evolution of galaxies becomes more important as the distance between galaxies generally increases. The largest galaxies in the loca…
[extra] Early (z>=2) massive quenched galaxies: accurate merger tree modelling and insights from COLIBRE ¶
Abstract: Understanding how massive quenched galaxies at z>=2, recently revealed in unexpectedly large numbers by JWST, form and evolve requires accurate models. I will first discuss challenges in semi-analytic models, w…
