Proximo Seminario: Galaxy and galaxy cluster formation and evolution from a theoretical point of view

Unexpectedly lonely galaxy discovered

An international team, including Carlos Donzelli, a researcher at the Instituto de Astronomía Teórica y Experimental (IATE) and the Observatorio Astronómico de Córdoba, made a finding that could challenge the timescales in which galaxies are expected to grow. These results were obtained using data from NASA’s Chandra X-ray Observatory and the Gemini International Observatory.

Abstract:

I will shortly review the state of the art in numerical computations concerning the formation and evolution of galaxy and galaxy clusters, in a cosmological environment. I will then describe our star formatiion and feedback model, MUPPI (MUlti-Phase Particle Integrator). In such a model, we solve the ODE system describing the mass and energy flows in a two-phases interstellar medium, particle by particle, taking into account the effect of the large-scale cosmological environment. I will show how such a model is able to produce realistic disk galaxies at relatively low resolutions. I will then describe the computations we performed at INAF-Trieste Astronomical Observatory on the galaxy cluster scales, focusing on our latest results and on the importance and delicacies of the (unavoidable!) sub-grid parametrizations.

I will conclude showing our future developments research paths.
