The formation and evolution of supermassive black holes, compact objects weighting up to billion solar masses and residing in the center of most galaxies, is still poorly understood. This thesis is devoted to the study of two main aspects of supermassive black hole physics. Using state-of-art numerical simulations, I have investigated in a first part the dynamics of supermassive black holes in two different models of galaxy mergers explaining the formation of the Giant Southern Stream, an extended stream of stars recently observed in the outskirts of the Andromeda galaxy (M31). By considering a more realistic model than what was proposed so far, I make a robust prediction for the projected position of the massive black hole progenitor in the first scenario corresponding to a minor merger between M31 and a satellite galaxy. I also study the trajectory of the satellite and show that it must have had a complex orbital history prior to the formation of the stream. In the second scenario, I demonstrate the possibility that a major merger between two-gas rich galaxies can lead simultaneously to the formation of the stream and the peculiar centralregion of M31 constituted of a double nucleus. The second part of the thesis is devoted to the connection between supermassive black holes and globular clusters. By compiling available measurements, I find evidence for a tight correlation between massive black hole mass and velocity dispersion of globular cluster systems. I also study interactions between star clusters and massive black holes and show that they can significantly alter the orbital evolution of a massive binary black hole system

The gravitational Universe and the rise of an entirely new astronomy using gravitational waves have been selected by ESA as the scientific theme for the future large space mission L3 planned for 2030 decade. In that context, eLISA (evolved Laser Interferometer Space Antenna) mission seems favored, and is besides preceded by the LISA Pathfinder mission, about to be launched (December 2nd), that aims to demonstrate the technology envisaged. The scientific outcome of this mission would be very wide, concerning at the same time fundamental physics, cosmology and astrophysics. The work described in this document allows to deliver a simulator reproducing the closed-loop dynamical behavior of a three-body system : the spacecraft and the two test-masses. The simulator is based on a Space State Model of the dynamical system, of the measurement and actuation systems and includes numerous modelled imperfections such as sensor noises and stray forces applied on the test masses (the inertial references of the system), hence allowing to study the impact of these imperfections on the detector performances. In particular, this simulation tool allows to perform preliminary estimates of a fundamental quantity, the residual acceleration, that will limit the sensitivity of eLISA to low frequency gravitational waves

Rollin, Guillaume. "Chaos dynamique dans le problème à trois corps restreint." Thesis, Besançon, 2015. http://www.theses.fr/2015BESA2028/document.
This work is devoted to the study of the restricted 3-body problem and particularly to the capture-evolution-ejection process of particles by binary systems (star-planet, binary star, star-supermassive black hole, binary black hole, ...). First, using a generalized Kepler map, we describe, through the case of 1P/Halley, the chaotic dynamics of comets in the Solar System. The here considered binary system is the couple Sun-Jupiter. The symplectic application we use allows us to depict the main characteristics of the dynamics: chaotic trajectories, KAM islands associated to resonances with Jupiter orbital motion, ... We determine exactly and semi-analytically the exchange of energy (kick function) between the Solar System and 1P/Halley at its passage at perihelion. This kick function is the sum of the contributions of 3-body problems Sun-planet-comet associated to the eight planets. We show that each one of these contributions can be split in a keplerian term associated to the planet gravitational potential and a dipolar term due to the Sun movement around Solar System center of mass. We also use the generalized Kepler map to study the capture of dark matter particles by binary systems. We derive the capture cross section showing that long range capture is far more efficient than close encounter induced capture. We show the importance of the rotation velocity of the binary in the capture process. Particularly, a binary system with an ultrafast rotation velocity accumulates a density of captured matter up to 10^4 times the density of the incoming flow of matter. Finally, by direct integration of the planar restricted 3-body problem equations of motion, we study the ejection of particles initially captured by a binary system. In the case of a binary with two components of comparable masses, although almost all the particles are immediately ejected, we show, on Poincaré sections, that the trace of remaining particles in the vicinity of the binary form a fractal structure associated to a strange repeller associated to chaotic open systems. This fractal structure, also present in real space, has a shape of two arm spiral sharing similarities with spiral structures observed in galaxies such as the Milky Way
Boldrini, Pierre. "The cusp-core problem in dwarf galaxies : new solutions." Thesis, Sorbonne université, 2020. http://www.theses.fr/2020SORUS082.
This doctoral research focuses on the nature of the dark matter (DM) and more particularly on the inconsistency of inner DM density profiles in dwarf galaxies, the cusp-core problem. We have found new resolutions of this cold DM challenge at small scales using high resolution fully GPU N-body simulations. First, we have re-investigated the Fornax cusp-core problem using observational results on the spatial and mass distributions of globular clusters in order to put constraints on the DM profile. Then, N-body simulations were designed to demonstrate that DM minihalos, as a new component of globular clusters, resolve both the timing and cusp-core problems in Fornax if the globular clusters were recently accreted. Secondly, we have examined whether DM candidates in the form of PBHs can solve the cusp-core problem in low-mass galaxies. This mechanism works for PBHs in the 25-100 Msol mass window but requires a lower limit on the PBH mass fraction of 1% of the total dwarf galaxy DM content. Then, we have demonstrated that subhalos sink and transfer energy via dynamical friction into the centres of dwarf galaxies. This dynamical heating kicks any central intermediate massive BH out to tens of parsecs. Finally, we demonstrate that accretion of a satellite on a highly eccentric orbit causes the formation a DM core and naturally explains a present BH offset by sub-parsecs in M31
Vaziri, Goudarzi Hamed. "Hole Dynamics in Films." Electronic Thesis or Diss., Sorbonne université, 2023. http://www.theses.fr/2023SORUS640.
Oceanic film bursting is a phenomenon in which a thin liquid film representing the cap of the bubble bursts at the surface of the ocean, producing film drops. The film bursting phenomenon is critical in ocean-atmosphere exchanges, particularly in transferring heat, mass, and momentum between the ocean and the atmosphere. The film bursting phenomenon comprises a series of complex dynamics, such as drainage, puncture, film retraction, and film disintegration into film drops. The hole healing (i.e., when a hole is too small and is closed after its nucleation) is a critical parameter that could impact the film bursting dynamics, particularly the film thickness at bursting and, thus, the liquid budget for the film drop production. The present work investigates the dynamics of holes in free liquid films, presenting a comprehensive understanding of the hole-healing phenomenon while focusing on the film bursting in the oceanic context. This was achieved through a combination of numerical simulations and analytical approaches. The numerical simulations were carried out using Basilisk. This robust and efficient two-phase flow solver is based on a Volume-of-Fluid (VoF) method and written using the C-programming language. The underlying mechanism for the hole-healing phenomenon was studied in detail. The dichotomy simulations for the determination of the healing threshold carried out in this work have used high-resolution mesh refinement. This was possible by using an adaptive mesh scheme provided by Basilisk. The analytical approaches were used to develop hypotheses to predict the healing threshold of a hole on a film, which were tested against numerical results. The critical dynamics of the hole are examined, and distinct power laws were identified for the tip curvature to illustrate the driving mechanism. The variations in the hole healing threshold with other problem parameters were examined. This study was first carried out for a flat film, discovering that the healing threshold is increased by increasing the film Laplace number. This effect was pronounced for values ranging from 1 to 10000, coinciding with the customary range of film Laplace numbers observed for oceanic bursting bubbles. The observed effects were also elaborated upon, along with physical explanations. Since the exact initial shape of the hole was shown to influence the healing threshold, an examination was carried out to study this effect on the consistency of the results from changing the film Laplace number, taken as an example for the other. It was shown that despite variations in the threshold for different shapes, the effect of changing the film Laplace number was independent of the hole shape. Therefore, the dichotomy results were shown to be independent of the arbitrary choice of the hole shape throughout the study. A similar study was carried out for a hole in a bubble cap after a detailed study of the bubble and gas outflow dynamics. It was discovered that the gas outflow undergoes a Venturi effect, where a stronger outflow, resulting from smaller bubble sizes or higher gas Laplace numbers, was shown to increase the healing threshold. A hypothesis was developed to predict the Venturi effect on the healing threshold, resulting in a Venturi correction term that predicted a power law dependency on the bubble diameter, which agreed with the numerical results. The Venturi effect was significant for high values of the gas Laplace number, where the healing threshold was doubled by increasing the film mean curvature from a flat film to a bubble cap with a size 20 times the bubble cap thickness. These findings provide a comprehensive understanding of the hole-healing phenomenon, particularly in oceanic film bursting. The present work also offers a foundation for future studies on the film-bursting phenomenon involving complex dynamics, including hole healing
