Transcript: Introduction PAR Ethnography Post-analysis data Analysing the data Literature Review Critique of Humean causality: much work in PA and H attempts to explain action (level of activity) by analysing variables (measurable independent variable). This can only lead to knowledge of behaviour through a closed account of linear and simplified causality. (eg. Little Jimmy watches too much TV because his dad watches too much TV). 5, 000 words... leave til last to write this section Research Aims Offering chaotic causality: Thousands of different influences which are in constant flux, the sum total of which manifest in action. 5 parts, each 8,000 words (publishable) total 40,000 words 10,000 words...

Heuristics 10,000 words - mid Nov - Jan Short summary of aims and questions Key Literature 5 - 10,000 words Discussion Empirical Findings How is the choice of methods and interpretation of data affected by particular questions and the nature of scientific objects? Present creative non-fiction at the start of each chapter which illuminates my point Producing data Knowledge (about health) and power (as a mediator) Language as a structured structuring structure Discourse and public knowledge - what we can and can't say, and what we can and can't think Methodology A Sociology of Physical Activity Promotion for Young People Methodological Approach Implications Visual Methods: Burke Sarah Pink Gillian Rose D. Macdougall What is important is not whether person X is a boy or a girl, but rather how that person perceives gender, how they relate to gender and how important gender is to their involvement with PA. Begin with summary Ethnography: Philosophy of science: Kuhn, T. The structure of scientific revolutions, 501/KUH Baskar, R. A realist theory of science... Reclaiming Reality Smith, John. The Logic of Justification Peters and Hurst Kant, Critique of Pure Reason Popper Hempel Hume Feyerabend The questions are about meaning, subjectivity, and influence of the social world. The objects are interpreted and socially constructed.

Transcript: Supervisor: Prof. F. Matteucci Student: Carlo M. De Masi University of Trieste - Final PhD Presentation 15/02/2019 THE EFFECT OF THE INITIAL MASS FUNCTION (IMF) ON THE CHEMICAL EVOLUTION OF ELLIPTICAL GALAXIES Introduction Intro Chemical evolution 01 Interpreting the chemical abundances observed in the dominant stellar population and in the gas of galaxies, which allow us to obtain constraints on their formation and evolution. Chemical evolution 02 Convenient to: use a logarithmic scale (small absolute values of quantities involved); refer to the analogous abundances in the Sun. Chemical evolution 03 Time-delay model abundance ratios as clocks; -elements → massive stars, short time-scale; Fe → Type Ia SNe, long time-scale; Early times: both alpha-elements and Fe produced → [ /Fe] ≈ constant; Later times: Type Ia SNe, new born stars “polluted” with Fe → [ /Fe] ratio decreases ; little to no gas → chemical abundances derived for stellar populations; few or no signs of recent star formation; increased strength of metal absorption lines with mass (mass–metallicity relation, MZR); higher stellar [ /Fe] ratios in more massive galaxies → stars in more massive ellipticals stopped forming before Type Ia SNe started polluting the ISM with Fe (“downsizing” in star formation); Elliptical galaxies Elliptical galaxies MZR [ /Fe]-mass Chemical Evolution Model Chemical evolution model Basic assumptions initial infall episode → burst of star formation thermal energy by SNe overcomes gas binding energy → galactic wind (GW) drives residual gas away from the galaxy, quenching star formation; star formation rate Direct/inverse wind models “Direct wind” models (Larson, 1974): SF efficiency constant/inversely proportional to mass; later wind in more massive galaxies (deeper potential well), prolonged star formation → MZR; lower [alpha/Fe] ratios!!! “Inverse Wind” model (Matteucci, 1994): higher nu in more massive galaxies; more efficient metals production → MZR; in spite of deeper gravitational potential well, GW starts faster, stars not “contaminated” by Fe (“downsizing” in star formation) → [alpha/Fe]-mass relation; Downsizing Two final steps: average abundances in the dominant stellar population: Mass/light-weighted abundances averaged chemical abundances to spectral indices (e.g. Mg2, <Fe>): Chemical evolution equation IMF 01 mass distribution of new-born stars Low-mass stars: bulk of Fe; lock baryonic matter away from ISM over Hubble time; dominate mass budget in galaxy. High-mass stars: alpha-elements; dominate integrated light; strongly influence energetic feedback by stellar winds and SNe. IMF 02 Solar vicinity: direct star counts (Kroupa/Chabrier invariant IMF): External galaxies: indirect methods one/multi-slope power law universal, time/space dependent skewed towards: small masses (bottom-heavy) high masses (top-heavy) Part I Part I Testing the downsizing scenario MOSES dataset (Thomas, 2010): 3360 galaxies, morphologically selected by visual inspection from the SDSS, in the redshift range 0.05 < z < 0.06 (Thomas 2010); stellar population parameters (luminosity-weighted ages, total metallicities and ratios) derived from the fitting of the 25 Lick absorption line indices to spectro-photometric models (Thomas 2003); MOSES Dataset Model 01: constant Salpeter (1955) IMF “inverse wind” model → increasing SF efficiency with galacticmass; Model 01 Comparison 01 Comparison 02 Model 02 Model 02: top heavier IMF in more massive galaxies : Comparison 01 Comparison 02 Model 03 Model 03: IGIMF basic idea: SF mostly in star clusters; within clusters → clusters → gwIMF → all the IMFs in all of the clusters: two main factors: → increases with SFR; → increases with IGIMF Comparison 01 Comparison 02 Conclusions - Part I: Downsizing in star formation not enough to reproduce the increase of with mass; Evidence for the necessity of assuming a top-heavier IMF in more massive galaxies; A variation of the IMF, passing from Scalo to Salpeter to Chabrier gives the best agreement with data; The IGIMF also predicts the right slopes of the observed relations, but produces too high abundances and abundance ratios; Conclusions I Part II Part II Bimodal IMF SPIDER (La Barbera et al. 2013) : 39993 nearby (0.05 < z < 0.095) ETGs from SDSS DR6 SPIDER sample; IMF constraints → high S/N needed; 20 mass-stacked spectra; total metallicity [Z/H] defined as: [Z/H] = [Fe/H] + 0.75 x [Mg/Fe] [Mg/Fe] ratio from the proxy derived from the spectra. SPIDER Dataset MZR Bimodal IMF (Vazdekis 1997, 2003) Bimodal IMF Model 04: bimodal IMF, bottom heavier in more massive galaxies. Model 05: explicitly time dependent form for the bimodal IMF (Weidner et al. 2013), slope value changing after a time interval tswitch (top → bottom heavier). Models grid Comparison 01 Model 01 Comparison 02 Model 02 Comparison 03 Model 03 Comparison 04 Model 04 Comparison 05 Model 05 Best models 01 Best models 02 all models matching the [Fe/H] and [Mg/Fe] simultaneously switch slope at the same
