Coudray, Armand. "Asymptotic behaviour of zero rest-mass fields on radiative space-times." Electronic Thesis or Diss., Brest, 2024. http://www.theses.fr/2024BRES0026.
Повний текст джерелаThis thesis adresses two distinct subjects. The first part examines the asymptotic behavior of scalar waves in the Vaidya spacetime, describing a spherical white hole evaporating via emission of isotropic dust. The analysis focuses on the regularity of conformal scalar waves at the isotropic boundary (past and future) of the compactified spacetime, depending on the initial data of the conformal field. Additionally, we construct the conformal scattering operator, demonstrating its ability to encode the entire field evolution in the compactified spacetime.These findings rely on energy inequalities and vector field methods.The second part centers on analyzing incoming isotropic curves in the purely radiative Robinson-Trautman spacetimes of type D. In contrast to a previous study on Vaidya’s metric, these curves do not form the past horizon due to the solution’s geometry. The final chapter categorizes these curves, revealing a behavior akin to that observed in Vaidya’s spacetime

Повний текст джерелаVibration damping of mechanical structures plays an important role in the design of many industrial systems. Classical methods for reducing vibrations using viscoelastic layers glued to the structure usually result in added mass on the treated structure, which may be prohibitive in the transportation industry for ecological and economical reasons. The "Acoustic Black Hole" (ABH) effect is a lightweight passive vibration technique: the flexural waves propagating in a beam extremity tapered with a power law profile are efficiently dissipated if an absorbing layer is placed where the thickness is minimum.A preliminary study experimentally confirms the potential of ABH as an efficient strategy for vibration damping: a modal analysis shows that the ABH significantly increases the Modal Overlap Factor (MOF) of the beam, thus reducing the resonant behaviour of the structure. An analysis based on a wave approach clearly shows that the reflection coefficient of an ABH termination has small values. Further investigations, including a two dimensional numerical model of the structure developed in order to understand its behaviour, show that the increase of MOF can be explained partly by an increase of the modal density and mostly by a high damping of a number of modes of the structure due to energy localisation in the tapered region. It is shown that the ABH beam possesses two-dimensional local modes. A waveguide model of an ABH termination with tip imperfection, which cannot be avoided in practice, shows that incident energy is scattered on local modes and that imperfections enhance the damping effect

Повний текст джерелаSagittarius A⋆ is the supermassive black hole at the Galactic center. Due to its proximity, this specimen is an excellent laboratory to study the accretion processes occurring around black holes and to constrain the duty cycle of these objects. Sgr A* is currently extremely faint and despite the detection of daily flares, its luminosity remains at least eight orders of magnitude below its Eddington luminosity, making this specimen one of the least luminous known supermassive black holes. The radiative processes responsible for the daily variations of its luminosity have not been clearly identified yet. We present the results of a multi-wavelength campaign observing Sgr A* simultaneously in X-rays and in the near-infrared, using the XMM-Newton observatory and the VLT/NACO instrument. We studied the spectral variability of Sgr A* using the infrared data we obtained through a spectro-imaging technique. Uncertainties linked to the systematic errors are still large but the first tests applied seem to show that the spectral index of Sgr A* could depend on the black hole luminosity. On longer timescales, we demonstrate that Sgr A* experienced a higher level of activity in the recent past. Indeed, echoes of its past activity can be detected in the molecular material surrounding the black hole. They are traced by a strong signal in the iron fluorescence line at 6.4 keV. We achieved a complete and systematic study of this variable emission detected from the central molecular zone, using Chandra and XMM-Newton observatories. Our results confirm that Sgr A* experienced intense flares in the past few centuries, with a luminosity at least six orders of magnitude higher than its current one. In particular, we highlight for the first time the existence of two distinct transient events of relatively short duration, which are probably due to catastrophic events. These results are the first step needed to include Sgr A*’s activity into a broader understanding of the galactic nuclei

Повний текст джерелаThe most general black hole solution of Einstein–Maxwell theory has been discovered by Plebański and Demiański in 1976.This thesis provides several steps towards generalizing this solution by embedding it into N = 2 gauged supergravity.The (bosonic fields of the) latter consists in the metric together with gauge fields and two kinds of scalar fields (vector scalars and hyperscalars); as a consequence finding a general solution is involved and one needs to focus on specific subclasses of solutions or to rely on solution generating algorithms. In the first part of the thesis we approach the problem using the first strategy: we restrict our attention to BPS solutions, relying on a symplectic covariant formalism. First we study the possible Abelian gaugings involving the hyperscalars in order to understand which are the necessary conditions for obtaining N = 2 adS4 vacua and near-horizon geometries associated to the asymptotics of static black holes.A preliminary step is to obtain covariant expressions for the Killing vectors of symmetric special quaternionic-Kähler manifolds. Then we describe a general analytic solutions for 1/4-BPS (extremal) black holes with mass, NUT, dyonic charges and running scalars in N = 2 Fayet–Iliopoulos gauged supergravity with a symmetric very special Kähler manifold. In the second part we provide an extension of the Janis–Newman algorithm to all bosonic fields with spin less than 2, to topological horizons and to other dimensions. This provides all the necessary tools for applying this solution generating algorithm to (un)gauged supergravity, and interesting connections with the N = 2 supergravity theory are unravelled

Повний текст джерелаIn this thesis, we take a systematic study of global regularity of the Maxwell equations and of the Yang-Mills equations on curved black hole space-times. In the first chapter, we write the proof of the non-blow up of the Yang-Mills curvature on arbitrary curved space-times using the Klainerman-Rodnianski parametrix combined with suitable Grönwall type inequalities. While the Chruściel-Shatah argument requires a control on two derivatives of the Yang-Mills curvature, we can get away by controlling only one derivative instead, and write a new gauge independent proof on arbitrary, fixed, sufficiently smooth, globally hyperbolic, curved 4-dimensional Lorentzian manifolds. In it's sequel, we study the Maxwell equations in the domain of outer-communication of the Schwarzschild black hole. We show that if we assume that the middle components of the non-stationary solutions of the Maxwell equations verify a Morawetz type estimate supported on a compact region in space around the trapped surface, then we can prove uniform decay properties for the components of the Maxwell fields in the entire exterior of the Schwarzschild black hole, including the event horizon, by making only use of Sobolev inequalities combined with energy estimates using the Maxwell equations directly. This proof does not pass through the scalar wave equation on the Schwarzschild black hole, does not need to separate the middle components for the Maxwell fields, and would then be in particular useful for the non-abelian case of the Yang-Mills equations where the separation of the middle components cannot occur. The last chapter is an opening to different problems in partial differential equations

Повний текст джерелаAn X-ray binary is a system containing a compact object (black hole, neutron star or white dwarf) accreting material from a companion star. The matter falling on the compact object is an emitter of X and even soft-gamma radiation. Searching and studying these objects, either transient or persistent, is one of the main goal of INTEGRAL, the in-orbit ESA mission devoted to X-ray and gamma-ray astrophysics. Scans of the Galactic plane and deep exposures of the Galactic Centre are performed periodically by INTEGRAL in the framework of the Core Programme guaranteed time. These regions are well known to be rich of X-ray binaries. Thanks to its unprecedented combined spatial resolution (12' FHM) and sensitivity, the IBIS/ISGRI telescope on board INTEGRAL provides high resolution images and good quality spectra in the energy range 15-600 keV. The work reported in this thesis is divided in two different parts which are linked to the status of the IBIS instrument during the different stages of its operation. In the first part, on-ground and in-flight calibration activities of the IBIS telescope are described. Observations of the Crab have been used in order to improve the spectral response matrix of the instrument; sensitivity and imaging capabilities have been accurately tested with several pointings of the Cyg X-1 region. In order to give an idea of the IBIS scientific performances, among the several results of the first year of observations, I briefly report on two key results I have been contributing: the first IBIS source catalogue and the origin of the Galactic diffuse emission between 20 and 100 keV, explained as being mainly due to the emission of previously unresolved Galactic point sources. The second part concerns data analysis and interpretation of three black hole binaries observed with INTEGRAL and simultaneously with two other X-ray satellites, namely XMM-Newton and RXTE. I present in this thesis the spectral evolution and luminosity variation of two transient black hole candidates, XTE J1720-318 and IGR J17464-3213, observed during their 2003 outburst activities. .
