Tesis (Doctor en Astronomía)--Universidad Nacional de Córdoba, Facultad de Matemática, Astronomía, Física y Computación, 2022.Fil: Dávila Kurbán, Federico. Universidad Nacional de Córdoba. Facultad de Matemática, Astronomía, Física y Computación; Argentina.En las escalas más grandes, nuestro Universo muestra características geométricas como cúmulos, filamentos y vacíos, que componen lo que se conoce como la Red Cósmica. Los vacíos son las regiones menos densas y, por tanto, uno de los entornos más extremos para que las galaxias se formen y evolucionen. Por tanto, las galaxias y su distribución en estos entornos constituyen la mejor aproximación a sus propiedades prístinas. Sin embargo, su estudio estadístico en estos entornos subdensos está limitado por el pequeño tamaño de las muestras. Esta Tesis propone nuevos enfoques estadísticos que se aplican en simulaciones y pretenden mejorar las herramientas de análisis, a saber: métodos de estudio de la agrupación de galaxias que reduzcan el error de las estadísticas o su tiempo de cálculo; estadísticas para el análisis de orientaciones de galaxias orientaciones de las galaxias que puedan utilizar toda la información disponible y con una determinación robusta de su significancia estadística; y, por último, un estudio de la agrupación de galaxias utilizando un método que, a diferencia de las estadísticas más habituales, analiza las regiones de exclusión de galaxias y, por lo tanto, es una elección natural para entornos subdensos. Hemos aprendido que los vacíos son un entorno único en el que la estructura puede formarse y evolucionar, y pueden desempeñar un papel crucial en la generación de momento angular y alienación de galaxias.On the largest scales our Universe displays striking geometrical features like clusters, filaments, and voids, that compose what is known as the Cosmic Web. Voids are the most underdense regions and thus one of the most extreme environments for galaxies to form and evolve. Therefore, galaxies and their distribution in these environments constitute the best approximation to their pristine properties. However, their statistical study in these subdense environments is limited by the small sample sizes. This Thesis proposes new statistical approaches that are applied in simulations and aim to improve the tools of analysis, namely: methods of studying the clustering of galaxies that reduce the error of the statistics or their computational time; statistics for the analysis of galaxy orientations that can use all the information available and with a robust determination of their statistical significance; and finally, a study of the clustering of galaxies using a method that, unlike the more usual statistics, analyses the regions of exclusion of galaxies and is therefore a natural choice for subdense environments. We have learned that voids are a unique environment in which structure can form and evolve and may play a crucial role in embedding galaxies with alignment and angular momentum.Fil: Dávila Kurbán, Federico.

A statistical formalism for alignment analysis

The detection of anisotropies with respect to a given direction in a vector field is a common problem in astronomy. Several methods have been proposed that rely on the distribution of the acute angles between the data and a reference direction. Different approaches use Monte Carlo methods to quantify the statistical significance of a signal, although often lacking an analytical framework. Here we present two methods to detect and quantify alignment signals and test their statistical robustness. The first method considers the deviance of the relative fraction of vector components in the plane perpendicular to a reference direction with respect to an isotropic distribution. We also derive the statistical properties and stability of the resulting estimator, and therefore does not rely on Monte Carlo simulations to assess its statistical significance. The second method is based on a fit over the residuals of the empirical cumulative distribution function with respect to that expected for a uniform distribution, using a small set of harmonic orthogonal functions, which does not rely on any binning scheme. We compare these methods with others commonly used in the literature, using Monte Carlo simulations, finding that the proposed statistics allow the detection of alignment signals with greater significance.Fil: Dávila Kurbán, Federico.

Spin alignment around Illustris-TNG voids

Using a new statistical approach we study the alignment signal of galactic spins with respect to the center of voids identified in the TNG-300 simulation. We explore this signal in different samples of galaxies, varying their distance from the void center, mass, spin norm, local density, and velocity. We find a strong tendency (>9 sigma) of massive, high-spin, and low radial velocity galaxies to be aligned perpendicularly to the void-centric direction in a wide range of distances corresponding to 0.9 to 1.4 void radii. Furthermore, we find that in these subdense environments, local density is irrelevant in the amplitude of spin alignment, while the largest impact is associated to the galaxy void-centric radial velocity in the sense that those at the lowest expansion rate are more strongly aligned perpendicularly to the center of the void. Our results suggest that further analysis at understanding intrinsic alignments and their relation to large scale structures may probe key for weak lensing studies in upcoming large surveys such as Euclid and LSST.Fil: Dávila Kurbán, Federico.

Void Probability Function inside cosmic voids: evidence for hierarchical scaling of high-order correlations in real space

We compare the reduced void probability function (VPF) inside and outside of cosmic voids in the TNG300-1 simulation, both in real and simulated redshift space. The VPF is a special case of the counts-in-cells approach for extracting information of high-order clustering that is crucial for a full understanding of the distribution of galaxies. Previous studies have validated the hierarchical scaling paradigm of galaxy clustering moments, in good agreement with the "negative binomial" model, in redshift surveys, but have also reported that this paradigm is not valid in real space. However, in this work we find that hierarchical scaling can indeed be found in real space inside cosmic voids. This is well fitted by the negative binomial model. We find this result to be robust against changes in void identification, galaxy mass, random dilutions, and redshift. We also obtain that the VPF in real space at high redshift approaches the negative binomial model, and therefore it is similar to the VPF inside voids at the present time. This study points, for the first time, towards evidence of hierarchical scaling of high-order clustering of galaxies in real space inside voids, preserving the pristine structure formation processes of the Universe.Comment: 12 pages, 8 figures.

Improved two-point correlation function estimates using glass-like distributions as a reference sample

All estimators of the two-point correlation function are based on a random catalogue, a set of points with no intrinsic clustering following the selection function of a survey. High-accuracy estimates require the use of large random catalogues, which imply a high computational cost. We propose to replace the standard random catalogues by glass-like point distributions or glass catalogues whose power spectrum P(k) â i k4 exhibits significantly less power on scales larger than the mean interparticle separation than a Poisson distribution with the same number of points. We show that these distributions can be obtained by iteratively applying the technique of Zeldovich reconstruction commonly used in studies of baryon acoustic oscillations (BAO). We provide a modified version of the widely used Landy-Szalay estimator of the correlation function adapted to the use of glass catalogues and compare its performance with the results obtained using random samples. Our results show that glass-like samples do not add any bias with respect to the results obtained using Poisson distributions. On scales larger than the mean interparticle separation of the glass catalogues, the modified estimator leads to a significant reduction of the variance of the Legendre multipoles ζíi(s) with respect to the standard Landy-Szalay results with the same number of points. The size of the glass catalogue required to achieve a given accuracy in the correlation function is significantly smaller than when using random samples. Their use could help us to drastically reduce the computational cost of configuration-space clustering analysis of future surveys while maintaining high-accuracy requirements.Fil: Dávila Kurbán, Federico.

The global environment of small galaxy systems

The main goal of this work is to investigate the influence of environment at different scales on the properties of galaxies in systems with a low number of members. To this end we used a catalogue of small galaxy systems comprising compact and locally isolated pairs, triplets and groups with four and up to six galaxies. We consider fixed aperture estimators and found that at scales lower than 5 Mpc pairs are associated to lower density environments than triplets and groups. Moreover a nearest neighbourapproach highlights that triplets prefer denser environments than pairs and slightly less dense environments than groups. When considering the position within the cosmic web we found that pairs and triplets in our sample are associated to void environments while galaxy groups are more likely to reside in void walls. In agreement with these results, the system-galaxy cross-correlation function shows that pairs inhabit environments of lesser density compared to triplets and groups, and on small scales (< 3Mpc) triplets appear to behave as an intermediate system. Related to the properties of neighbour galaxies of small systems we found that the neighbours of groups present a lower fractions of star forming, young stellar population and blue colour galaxies with respect to neighbours of triplet and pair systems. These results suggest that differences in the properties of galaxies in pairs, triplets and groups are not only related to the existence of an extra galaxy member but also to the large scale environment inhabited by the systems.Fil: Duplancic Videla, Maria Fernanda.
