Cosmological Hydrodynamical Simulations as a Tool to Study the Universe
a talk by Prof. Maria Celeste Artale (Universidad Andres Bello, Chile) - In-Person
Abstract:
Cosmological hydrodynamical simulations are a powerful tool for exploring and predicting different aspects of the Universe. On one hand, these simulations improve our understanding of how stellar evolution influences the formation and evolution of galaxies. On the other hand, it allows us to explore the large-scale structure of the cosmos. In this talk, I will show how I exploit cosmological hydrodynamical simulations in my current research. Specifically, I will focus on two aspects: 1. The identification of likely host galaxies for binary compact object mergers. By integrating synthetic galaxy catalogs with stellar evolution models, we can investigate the properties of host galaxies and their progenitors, such as high-mass X-ray binaries. 2. The evolution of galaxy populations within high-redshift protoclusters into the massive clusters we observe today. I will show how simulations map different galaxy populations (such as Lyman-alpha emitters and submillimeter galaxies) in protocluster regions and offer robust predictions for upcoming surveys. Finally, I will discuss how future simulations will shed light on the processes shaping our Universe.
Short-Bio:
I am an Assistant Professor at Universidad Andres Bello in Chile. I am a theoretical astrophysicist with experience in hydrodynamical cosmological simulations to investigate open questions in galaxy formation, cosmology, and gravitational‑wave astronomy. I am originally from Argentina. I obtained my PhD in 2015 at the University of Buenos Aires, Argentina. After I obtained my PhD, I was a postdoctoral fellow at the University of Innsbruck, Austria. During this period, I started to work on the host galaxies of merging compact binaries, which is my current main research field. In 2021, I was awarded the MSCA Seal of Excellence UniPd, and between 2021-2023, I was a postdoctoral fellow at the University of Padua, Italy, and also a research visitor at Purdue University in the USA. I am currently a member of the Observation Science Board of the Einstein Telescope (a proposed third-generation ground-based gravitational wave detector proposed by institutions in the European Union) and also involved in the ODIN survey, devoted to investigating the cosmic structures in the early Universe.
