Past Events
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…
The hunt for dark matter using galaxy clusters ¶
Abstract: Dark matter constitutes the majority of the matter content of the Universe, yet its fundamental properties remain unknown. Its presence is inferred through its gravitational effects on cosmic structures of all…
[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…
