Book Description
This interdisciplinary thesis addresses spiral galaxy formation and dark matter phenomenology as well as its detection by the ANTARES neutrino telescope. A suite of high-resolution cosmological hydrodynamics simulations, with theadaptive mesh refinement code RAMSES, of the same galaxy, is performed using different modellings of stellar formation (Kennicut law (KS) versus gravo-turbulent criteria (multiFF)) and supernovae feed back (delayed cooling (DC) versus mechanical feedback (ME)). The results on the morphology and the properties of the galaxies are compared to observational constraints and high light the impact of baryonic physics on a spiral galaxy. The most elaborated scenarios (multi FF+DC or multi FF+ME) are clearly favoured and give rise to more realistic stellar mass and disc morphology.The resulting dark matter distributions in halos are also analyzed and compared showing some significant differences. The understanding of baryonic physics is crucial to understand the dark matter distribution. Namely, it is specifically modified and contracted by the baryonic potential of each simulation with a determining impact on direct and indirect dark matter detection. Moreover,we also use those informations about the dark matter to probe the Eddington inversion method aiming at predicting phase-space distribution from the gravitationnal potential. Those results are positive and very consistent and promisingin view of GAIA data analysis improvement and calibration. Further more, we also revisit the astrophysical uncertainties related to the dark matter velocity distribution relevant in the capture by the Sun and evaluate those effects to about 15-20% on the capture rate.

Book Description
This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Book Description
At least eighty percent of the mass of the universe consists of some material which, unlike ordinary matter, neither emits nor absorbs light. This book collects key papers related to the discovery of this astonishing fact and its profound implications for astrophysics, cosmology, and the physics of elementary particles. The book focuses on the likely possibility that the dark matter is composed of an as yet undiscovered elementary particle, and examines the boundaries of our present knowledge of the properties such a particle must possess.

Book Description
Dark matter is among the most important open problems in modern physics. Aimed at graduate students and researchers, this book describes the theoretical and experimental aspects of the dark matter problem in particle physics, astrophysics and cosmology. Featuring contributions from 48 leading theorists and experimentalists, it presents many aspects, from astrophysical observations to particle physics candidates, and from the prospects for detection at colliders to direct and indirect searches. The book introduces observational evidence for dark matter along with a detailed discussion of the state-of-the-art of numerical simulations and alternative explanations in terms of modified gravity. It then moves on to the candidates arising from theories beyond the Standard Model of particle physics, and to the prospects for detection at accelerators. It concludes by looking at direct and indirect dark matter searches, and the prospects for detecting the particle nature of dark matter with astrophysical experiments.

Book Description
Based on a Simons Symposium held in 2018, the proceedings in this volume focus on the theoretical, numerical, and observational quest for dark matter in the universe. Present ground-based and satellite searches have so far severely constrained the long-proposed theoretical models for dark matter. Nevertheless, there is continuously growing astrophysical and cosmological evidence for its existence. To address present and future developments in the field, novel ideas, theories, and approaches are called for. The symposium gathered together a new generation of experts pursuing innovative, more complex theories of dark matter than previously considered.This is being done hand in hand with experts in numerical astrophysical simulations and observational techniques—all paramount for deciphering the nature of dark matter. The proceedings volume provides coverage of the most advanced stage of understanding dark matter in various new frameworks. The collection will be useful for graduate students, postdocs, and investigators interested in cutting-edge research on one of the biggest mysteries of our universe.

Book Description
One of the major open questions in high energy physics and cosmology is the nature and origin of dark matter. Dark Matter in Astrophysics and Particle Physics 1998 provides a comprehensive overview of the current status of research in this topical field. The book brings together leading researchers from around the world to review recent progress and future directions for research in the different approaches to the dark matter problem. It collects results from cosmology, large-scale structure, and accelerator and nonaccelerator physics. The book also reviews the correlations between and the virtues of each of the fields for the determination of abundance, nature, and origin of dark matter.
