Numerical modelling of the large-scale Universe: Euclid baseline model and alternative scenarios

Sala 1.4.14, FCUL, Lisboa

Por António Silva (IA).

Abstract: The advent of the ESA Euclid space mission (www.euclid-ec.org) brought new critical challenges to the numerical modeling of large-scale structure (LSS) in the Universe. On one hand, the mission science requirements impose levels of accuracy on a wide range of length and mass scales that implied a new exascale computing model, never achieved in cosmology. On the other hand, new physical effects and “alternative” (to LambdaCDM) cosmology scenarios also require new survey dedicated simulations to realistically assess model signatures and degeneracies, and to develop optimal estimators and efficient data analysis pipelines. In this talk I will provide with a brief introduction to the numerical techniques that can be used to model the formation evolution of cosmological structure, and describe the ongoing efforts to obtain a new set of LSS simulations that achieve the required accuracy for the baseline cosmology of Euclid as well as explore “additional” physics and “alternative” cosmologies to be tested against observational data.

Short bio: A. da Silva's main research is in observational Cosmology and numerical Astrophysics, in the topics of formation and evolution of cosmic structure, CMB radiation and the physics of Galaxy Clusters. He has been an active member of the largest international consortia for observational Cosmology: the ESA Euclid and Planck satellite missions. He obtained his PhD in Physics - Astronomy by the University of Sussex, UK. He is currently an Investigador FCT (development level) at the DF-FCUL. Previously he was Prof. Auxiliar Convidado, also at the DF-FCUL, and investigador Ciência 2007 at CAUP. Before these, he had research contracts and a Marie-Currie position in France at the (IAS – Paris and at OMP – Toulouse) as well as prestigious visiting grants at LATT in 2009 by CNRS, France; and at NAOJ Mitaka in 2004 by the JSPS, Japan.

Objectives: Evolutionary theory provides a framework for understanding all living systems.

Overview: Currently, climate changes or alterations are known to be reflected on the stable isotope ratios of Hydrogen, Nitrogen, Carbon, Oxygen and Sulphur present in atmospheric gas forms, fresh or ocean water, as well as in plants and animals and organi

Objectives: To introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

Objectives: Natural history museums are privileged spaces for seminal research on different subjects of biological sciences such as biodiversity, evolution, ecology, biogeography and taxonomy.

Objectives: Provide students with basic workflows, platforms and tools to increase reproducibility at all scientific levels.

Objectives: Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity.

Objectives: The objective of this course is to introduce participants to the details of communication and writing scientific publications. The main emphasis is on the most common form, the “primary scientific paper”, but other forms will be covered.

Objectives: Lack of fertile land to feed the exponentially growing population, insufficient water availability and quality, changes in the flow of nutrients through the bio-geo-cycles (especially N and P) and climate and land use changes are impacting ecosystem

Objectives: Symbiosis is a key strategy for life on Earth.

Objectives: The goal of this course is to provide to the participants with current and practical knowledge on urban ecology, including ecological and social aspects. It aims at providing an integrated approach on urban socio-ecological systems.

Objectives: Citizen science can be part of the larger process of engaging people in new forms of interaction in scientific research, challenging scientists and citizens whilst enlarging scientific knowledge and providing learning opportunities for all part

Objectives: This course aims at: 1) exploring how scientists can use social media as tools to enhance the communication of their research and the dialogue with society, and 2) discussing the differences that exist in the work of scientists and journalists

Objectives: This course will teach how to apply the SWAT eco-hydrological model to assess the impacts of climate and associated changes on water-soil-plant interactions, and consequences to water resources, soil erosion and nutrient cycles.

Objectives: Provide students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.
