    Studying the Milky Way evolution with SPH + N-body models

    The Milky Way experienced several merger events which left their imprints on the stellar halo. In particular, it is known that a major merger happened during the Galaxy’s first Gyrs and, likely, perturbed its disc-shape structure. To fully understand the effects of such an event, we need to know the chemical and dynamical characteristics of the young Milky Way, i.e., before the major merger event, and the accreted satellite. For this purpose, SPH + N-body models guide us to explore formation scenarios of Milky Way-like galaxies that went through similar merger events. Such idealized models enable us to control the initial conditions of the merger and which physical processes are included, therefore understanding them better. This talk is divided into three parts. First, I explore the evolution of isolated simulation galaxies with different star formation prescriptions and find evidence supporting a clumpy star formation phase in the young Galaxy. For instance, the kinematic and chemical properties of stars near the Sun, commonly associated with the effects of a merger, can be explained by a clumpy formation scenario. This scenario is supported by observations of high redshift (z>1) galaxies with highly dense clumpy regions. Secondly, I introduce the Gaia-EncelAdus-Sausage Timing, chemistRy and Orbit (GASTRO) library: a suite of simulations exploring the parameter space for GSE-like accretion events and its impact on the formation history of the MW. Finally, I use a subset of the GASTRO library and explore the chemodynamical properties of the accreted stars and the implications to the known substructures in the stellar halo of our Galaxy.

    O PROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA convida para o seminário:

    Um modelo semiempírico para espalhamento elétron-átomo em baixas energias
    Prof. Dr. Felipe Arretche
    Departamento de Física – UFSC

     

    *Evento de presença obrigatória da disciplina seminários

    Resumo: Colisões de elétrons com átomos e moléculas formam um ingrediente fundamental na modelagem de plasmas atmosféricos e astrofísicos. A descrição do processo de termalização destes ambientes exige que sejam conhecidas as seções de choque elétron-átomo na chamada região de “baixas energias” (E < 20 eV). Neste seminário vamos apresentar uma metodologia semiempírica para modelar estas colisões com foco nos dados experimentais mais precisos já apresentados até hoje na literatura. Faremos uma exposição didática da teoria de espalhamento por um potencial descrevendo as várias nuances na modelagem das interações elétron-átomo em vácuo. Por fim, discutiremos os problemas em aberto e as perspectivas para o futuro nesta linha de pesquisa.

    Data: 24 de novembro de 2023 (sexta-feira) – Horário: 10h15min

    O PROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA convida para o seminário:

    Opportunities, recent results, and my personal experience in large facilities
    Dr. João Elias Figueiredo Soares Rodrigues
    ALBA Synchrotron Light Source, Barcelona – Espanha

    *Evento de presença obrigatória da disciplina seminários

     

    Resumo:
    In this seminar, I will briefly summarize what I have done so far in the European facilities concerning new materials for energy-recovery, unusual magnetic properties in perovskite materials, and coupling of different experimental techniques to build a complete scenario on the physical properties of a particular material. Currently, I have a post-doc scientific position at the beamline MSPD (Materials Science Powder Diffraction) of the ALBA Synchrotron Light Source (Barcelona, Spain). I have obtained a PhD degree in Applied Physics at University of São Paulo (2017), master degree (2012), and bachelor (2010) in Physics at Federal University of Maranhão. I was visiting postdoc fellow at the Instituto de Ciencias de Materiales de Madrid (2018-2020) at the Jose Antonio Alonso’s laboratory. From 2020-2023, I had a post-doc scientific position at the beamlines ID24/BM23 (High-brilliance X-ray absorption spectroscopy) of the European Synchrotron Radiation Facility (ESRF, Grenoble, FR). My research program is focused on high-pressure synthesis and characterization of novel energy materials for mainly thermoelectric applications. Other research activity in the field of high-pressure synthesis includes transition metal oxides with unusual electronic and magnetic properties. General research interest is in materials physics, including vibrational spectroscopy, electrical and magnetic characterization, and structural modeling. I am a frequent user of synchrotron and neutrons facilities (X-ray and neutron diffraction, X-ray absorption) applied to the determination of crystal and local atomic properties of different materials. I have more than 55 articles with more than 550 citations.

  • Professor Ivan Helmut Bechtold has been elected as the President of the Brazillian Materials Research Society

    Publicado em 07/11/2023 às 09:41 PM

    Professor Ivan Helmuth Bechtold, a full professor in the Physics department at the Federal University of Santa Catarina (FSC/UFSC), has been elected as the President of the Brazilian Materials Research Society (SBPMat) for the term spanning 2024-2025. Notably, this marks the first time that a leader from the southern region of Brazil has chaired SBPMat, as all previous presidents hailed from the Southeast.

    SBPMat is an organization that unites researchers from diverse fields, including Physics, Chemistry, Mathematics, Biology, Health Sciences, Agricultural Sciences, and Engineering, who are engaged in studies focused on the practical applications of materials. The annual flagship event of SBPMat, known as the Brazilian Materials Research Society (B-MRS), typically draws around 1,500 participants from across Brazil and various other countries.

    Produção exclusiva de mésons vetoriais em colisões ultraperiféricas de íons pesados no formalismo de dipolos de cor com distribuição assintótica de glúons
    Prof. Dr. Daniel A. Fagundes
    Física, UFSC – Campus Blumenau

    *Evento de presença obrigatória da disciplina seminários

    Resumo:
    Processos de produção exclusiva de mésons vetoriais em colisões ultraperiféricas de íons pesados (UPCs) tem sido amplamente estudados no LHC, especialmente pelas colaborações CMS, ALICE e LHCb. Em virtude de sua importância para a verificação de predições do formalismo perturbativo QCD e para sondagem de efeitos de saturação partônica, o estudo de UPCs tem atraído grande interesse nos últimos anos por parte da comunidade de física de altas energias.

    Nesse seminário apresentaremos alguns dos resultados recentes obtidos no LHC para a produção de mésons vetoriais (\rho, J/\psi, \psi(2s) e \varUpsilon) em colisões pp  (próton-próton) [1], pA (próton-núcleo) [2] e AA (núcleo-núcleo) [3] à luz de um modelo construído no formalismo de dipolos de cor [4], com base numa solução assintótica das equações DGLAP para a distribuição de glúons, xg(x,\mu^2). Como demonstrado em [5], esse modelo é capaz de reproduzir adequadamente os dados de alta precisão obtidos pelo experimento HERA para as funções de estrutura do próton F_2, F_L, F_2^{c\c}, F_2^{b\b}, bem como as  seções de choque de fotoprodução dos mésons \rho e J\psi. Adicionalmente, em um novo estudo (em curso) [6], demonstramos a sua aplicabilidade em UPCs, obtendo boas descrições dos dados experimentais recentes de distribuições de rapidez e seções de choque em colisões p-Pb (próton-chumbo), Pb-Pb (chumbo-chumbo) e Xe-Xe(Xenônio-Xenônio) no LHC. Por fim, demonstramos ainda o sucesso do modelo na descrição de processos ultraperiféricos com excitação Coulombiana do núcleo, em que ocorre a produção do méson vetorial acompanhada da emissão de um ou mais nêntrons.
