Pełny tekst źródłaThis thesis project presents several studies that are focused on the investigation of the chemical properties of different stellar populations in the Milky Way by means of high-resolution spectroscopy.The thesis is structured as follows:The first chapter is an introduction to the thesis project, and is divided into three sections. The first section describes the structure and formation scenarios of the Milky Way, in particular by referring to the most recent discoveries. The second section introduces the basic concepts and objectives of the studies presented in this thesis work. The third section describes the methods used to analyse the spectroscopic data.The second chapter presents the studies carried out in the context of the MINCE project. The first study is devoted to the chemical analysis of a sample of young giant stars that was serendipitously discovered during the first MINCE observations. My contribution in this work was to derive the stellar parameters, analyse the spectroscopic data, measure the rotational velocities, compare the results with theoretical models and write the paper. The second study presents the results obtained from the analysis of the first sample of MINCE stars. In this work, I contributed to the analysis of some of the stars in the sample.The third chapter presents the results obtained in the context of the CERES project. The first study presents a detailed chemical analysis of the star RAVE J110842.1-715300, with the aim of understanding whether or not it originated in the Omega Centauri globular cluster. My contribution in this study was to derive the stellar parameters of the star. The second study presents the results obtained for the CERES star sample. My contribution was to derive the parameters, compute model atmospheres, measure the chemical abundances, and write the paper.The fourth chapter presents the results obtained in the context of the High-speed stars project. The first study reports the results obtained from the high-resolution follow-up of two young and metal-poor stars in the sample of Caffau et al. (2020), to check whether they are blue stragglers or not. My contribution in this study was to obtain the high-resolution observations with UVES and to analyse the data. These results have not been published yet. The second study presents a detailed analysis of two high-speed stars observed with Subaru. In this study I was involved in the C abundance determination.The fifth chapter presents the results obtained from the chemical analysis of samples of stars selected using the Pristine photometry. The first study presents the chemical analysis of a sample of metal-poor stars that may have been enriched by the explosion of pair instability supernovae. My contribution was to select promising candidates and observe them with the SOPHIE spectrographat Observatoire de le Haute Provence (OHP)in visitor mode. The second study presents the preliminary results obtained from the chemical analysis of a sample of Pristine extremely metal-poor candidates. My contribution in this study was to derive the stellar parameters and the chemical abundances. The paper is in preparation.The sixth chapter concludes the thesis and gathers final reflections and future projects

Pełny tekst źródłaThis thesis presents the measurement of the photometric redshifts and physical parameters in the framework of large scale surveys, and their constraint on galaxy evolution. The photometric redshift measurement allows us to study the entire photometric sample. For this reason, the weak lensing signal measurement used in the Euclid mission as a primary cosmological probe will rely on photometric redshift measurements. However, the method is strongly affected by the quality of the photometry. In particular, I show in this thesis how the photometric calibration impacts the photometric redshift precison, in order to constrain the photometric strategy to use in the Euclid mission.Aiming to take into account for observationnal problems, the analysis is done with observationnal data whose photometric configuration is close to the expected Euclid one. These data combine new near-infrared observations conduected to cover the VIPERS spectroscopic survey and the CFHTLS photometry.Using the conclusions of this analysis, I have producted the new photometric catalogue for VIPERS and the associated photometric redshift calalogue.Finally, I used the same photometry to compute the stellar masses of 760,000 galaxies covering 22 square degrees at the limiting magnitude Ks(AB) < 22. This enabled me to study the evolution of the stellar mass function between redshifts z= 0.2 and z = 1.5. We have then shown that the star formation of galaxies with stellar masses around log(M/Msol) = 10.66 is stopped in 2-4 Gyr, while in quiescent low-mass (log(M/Msol) < 9.5) galaxies, the star formation has been stopped 5-10 times faster (approximatelly in 0.4 Gyr)

Pełny tekst źródłaActual models and observations of the Universe agreed at large scale. But the formation of baryonic structures remains unknown. To constrain structure formation in the Universe, observatoins are needed at different redshift to see different evolution steps. Planck satellite gives an acces to objetcs in the redshift range z=2 to z=4. Thus we detect about 1200 extragalactic objects in 26% of the sky near galactic poles, candidates to be at high redshift. A sample of 228 sources is observed at higher sensibility and resolution than Planck with Herschel satellite. This lead to resolve ponctual Planck sources in several Herschel sources. So I identify three possible types of object : candidates sources of gravitationally amplified lenses, galaxy cluster candidates and alignement of sources along the line of sight. I find in the sample 11 sources amplified by gravitationnal lensing, some of the brightest of the submillimeter sky. Those have redshift between z=2.2 and z=3.6 (Canameras et al., 2015) and provide a zoom in the stellar formation of the far Universe. It let 217 overdensity of sources that I study. With their colour in Herschel data, I find an estimate of their density. 50% of Herschel fields have an overdensity greater than 10sigma using red sources colour selection (S250/S350 < 1.4 et S500/S350 > 0.6). This show that our ample is mainly composed of red overdensity. Fitting Herschel-SPIRE photometry with a modify black body at 35K, I show that the photmetric redshift distribution of Herschel sources peaks around z=2. Our sample is now composed of 11 lensed sources and 217 galaxy cluster candidates at z~2. These galaxy cluster candidates contain an average of 9 SPIRE sources in 4.5’ diameter beam. Individual sources have a luminosity distribution peaking at 4.1012 Lsun which leads to a star formation rate (SFR) of 700 Msun.yr-1 (Bell et al. 2003). This gives an estimate structure luminosity of 4.1013 Msun and an SFR of 7000 Msun.yr-1 assuming that sources are members of the same structure. Our sample traces dense structure at high star formation rate in the full sky. This sample will be a key in the comprehension of structure formation and star formation at redshift about z=2

Pełny tekst źródłaStudying the evolution and the composition of the largest stuctures of the Universe, e.g., galaxy clusters and cosmic filaments, is one of the most challenging research topic in cosmology. During my phD thesis, I have analysed publicly available multi-wavelength surveys (namely SDSS, WISE, Planck), using new techniques in data analysis such as machine learning or Bayesian methods. The purpose of my work was to study the baryonic matter (hot gas and galaxies) in the intra-cluster medium, and in the cosmic web (bridges of matter between clusters of galaxies and cosmic filaments).During my thesis, I have developed an algorithm based on machine learning in order to estimate galaxy properties, such as star formation rate and stellar mass in the redshift range 0.050.5 were observed with VLT/FORS2. The analysis of the ~3000 obtained spectra is still ongoing and with the actual data, we expect the spectroscopic confirmation of about 10 galaxy clusters with about 10 members per clusters.The gas content of the cosmic web may account for about 40% of the baryons. Therefore, it is important to use optimised observational tracers of the gas. In this purpose, I have developed a deep learning algorithm using the full potential of the Planck data to detect the SZ effect tracing galaxy clusters and hot ionised gas. I have trained a convolutional neural network on the Planck frequency maps to recognize clusters selected in tSZ, X-rays, and optical. With this trained model I have generated a full-sky map of low noise SZ signal, in which I have detected about 10 times more candidates than the first Planck catalogue of SZ sources. I have shown that deep learning seems a promising approach to improve the y-map and detect smaller pressure halos and diffuse gas in the cosmic web
