    Enriquecimento químico de galáxias em grandes bases de dados

    Profa. Dra. Natalia Vale Asari

    UFSC/FSC

    Abstract:

    Oxigênio, nitrogênio, carbono. Ferro, níquel, molibdênio. A maioria dos elementos químicos mais pesados do que hidrogênio e hélio foram formados por nucleossíntese estelar. O ciclo de conversão do gás em estrelas e de estrelas em gás, portanto, regula o enriquecimento químico de uma galáxia. Bases de dados de milhões de espectros nos permitiram obter leis empíricas entre propriedades físicas de galáxias, como massa estelar, taxa de formação estelar e abundâncias químicas. Essas leis nos fornecem pistas sobre a interdependência entre a história de formação estelar e da evolução química de galáxias. Neste seminário, explicarei como os espectros de galáxias contém as impressões digitais da microfísica das nebulosas. Mostrarei também resultados de nossos trabalhos recentes com uma grande base de dados de espectroscopia integral. Darei destaque ao papel do gás difuso, e como ele pode enviesar a inferência de abundâncias químicas em galáxias.

    Modelos microscópicos em econofísica para sociedades estratificadas a priori

    Prof. Dr. Thiago Dias

    UTFPR

    Abstract:

    Nesse trabalho são apresentados dois diferentes modelos para trocas de riqueza em uma sociedade composta por dois grupos distintos. No primeiro modelo as trocas acontecem em pares aleatoriamente escolhidos. Diferentes fatores de proteção sociais e número relativo de transações entre agentes dos diferentes grupos são considerados. O segundo modelo considera redes dinâmicas que podem ser alteradas a cada passo de tempo e as trocas econômicas acontecem entre os agentes vizinhos na rede. É investigado o papel da homofilia dos grupos nos indicadores econômicos e na rede.

    Luz estruturada e emaranhamento

    Prof. Dr. Antonio Zelaquett Khoury

    Laboratório de Óptica e Informação Quântica – UFF

    Abstract:

    Neste colóquio discutiremos como os conceitos de informação quântica servem à descrição de configurações interessantes do campo ótico naquilo que hoje denominamos “luz estruturada”. A combinação de diferentes graus de liberdade da luz permite estabelecermos uma equivalência formal entre configurações estruturadas do campo eletromagnético e os estados emaranhados da mecânica quântica. Para além de uma mera equivalência formal, este paralelo inspira novas abordagens dos fenômenos óticos envolvendo os momentos angulares de spin e orbital da luz, bem como novas formas de combinar estas grandezas em processos não lineares. Este tema tem se revelado muito fértil, sendo a base do trabalho de diversos grupos de pesquisa internacionais, além de compor um cenário de cooperação científica entre diferentes grupos no Brasil.

    Structured light for computation and light conversion

    PhD Nara Rubiano da Silva

    Postdoc fellow – GIQSul – UFSC

    Abstract:

    Structured light displays intricate field distributions (of intensity, phase, polarization) in space, with several emerging applications. In the Quantum Optics Laboratory at UFSC, we study classical and quantum processes utilizing such optical fields. In this talk, I will present two of our recent results in the classical regime. Firstly, we manipulate the phase of light for realizing a computational task, namely, a matrix-by-vector multiplication. Each matrix or vector element is mapped into the tranverse phase distribution of the light beam, and the required operations are realized by optical elements. I will introduce this optical processor and, as an example, its application to an optimization problem called unidimensional Distance Geometry Problem. In a second work, we investigate a fundamental aspect of employing structured beams of the Laguerre-Gauss family in stimulated parametric down-conversion. Specifically, we analyse the selection rules involving the radial order of the resulting LG beams, which I will discuss in my talk.

    Detailed chrono-chemo-dynamics of seven metal-poor red giants from Kepler

    Arthur Alencastro Puls

    Research School of Astronomy and Astrophysics, Australian National University

    Abstract:

    The Kepler mission has yielded a revolution in the field of GalacticArchaeology, with its photometry allowing the determination of stellar parameters with an unprecedented level of precision for Red Giant stars. Recent studies have shown that a few of these objects display conflicting characteristics in the age-metallicity space (e.g., young and metal-poor). In this project we combine asteroseismic information from solar-like oscillations, high-resolution spectroscopy and Gaia astrometry to derive stellar ages, chemical abundances and kinematics for a group of metal-poor Red Giants, and characterise them in a multidimensional chrono-chemo-dynamical space. Our results suggest that underestimated parallax errors make the effect of Gaia parallaxes more important than different choices of model grid or – in the case of stars ascending the RGB – mass-loss prescription. Two stars are identified as potentially evolved halo blue stragglers. Four objects are likely members of the accreted Milky Way halo, and their possible relationship with known accretion events, such as Gaia-Sausage and Gaia-Sequoia, is discussed.
