Este martes 3 de junio, el Dr. Antonio D. Montero-Dorta, profesor de la Universidad Técnica Federico Santa María, presentará el seminario “The Multi-Scale Interplay Between Dark and Luminous Matter” a las 14:30 horas en la Sala 208 del Instituto de Física, Campus Curauma, PUCV.
Compartimos el abstract de la presentación:
The prevailing paradigm of galaxy formation posits that galaxies form within dark matter halos, which provide the potential wells needed for baryonic matter to accumulate, cool, and condense. Halos, in turn, are collapsed structures that originate from the high-density peaks of the underlying matter field. These objects are connected, albeit in a complex way, by their internal properties, clustering, and responses to the environment.
Characterizing the mapping between galaxies, halos, and the matter density field is essential not only for extracting cosmological information from galaxy surveys, but also for uncovering the physical mechanisms that shape galaxy evolution.
In this talk, I will present recent analytical and data-driven advances that enable a more detailed statistical dissection of halo and galaxy clustering in cosmological simulations, paying special attention to key physical phenomena such as assembly bias and the connection between clustering and the cosmic web. I will also discuss the observational detectability of these effects, along with the application of innovative techniques to data from upcoming large-scale galaxy surveys.
Extendemos la invitación a la comunidad del Instituto de Física y público interesado a participar de este seminario que busca aportar a la comprensión de la estructura del universo.
