Évolution de la dynamique des galaxies en fonction de leur environnement au cours des dix derniers milliards d'années avec MUSE-VLT
Autor: Mercier, Wilfried
Publikováno v: Galactic Astrophysics [astro-ph.GA]. Université Paul Sabatier-Toulouse III, 2022. English. ⟨NNT : 2022TOU30264⟩
Understanding the morphological and dynamical evolution of galaxies across cosmic time is one of the key goals of modern extragalactic astrophysics. Our current view is that galaxies are objects that evolve secularly and build their stellar mass thro

Etude du centre galactique et recherche de matière noire avec la H.E.S.S. Inner Galaxy Survey
Autor: Montanari, Alessandro
Publikováno v: High Energy Physics-Experiment [hep-ex]. Université Paris-Saclay, 2022. English. ⟨NNT : 2022UPASP098⟩
Very high energy (VHE, E ≥ 100 GeV) astrophysics pioneered the study of non-thermal processes describing cosmic rays (CRs) accelerated by galactic and extragalctic objects. CRs can be investigated by observing the Galactic Center (GC), which hosts

Recherche de matière noire légère avec l’expérience DAMIC-M
Autor: de Dominicis, Claudia
DAMIC-M (Dark Matter in CCDs at Modane) is a near-future experiment that aims at searching for low-mass dark matter particles through their interactions with silicon atoms in the bulk of charge-coupled devices(CCDs). Pioneer in this technique was the

Étude analytique de la structuration de la matière noire aux petites échelles et implications pour les recherches de nouvelle physique
Autor: Facchinetti, Gaétan
Publikováno v: Cosmology and Extra-Galactic Astrophysics [astro-ph.CO]. Université Montpellier, 2021. English. ⟨NNT : 2021MONTS037⟩
The problem of the missing mass of the Universe is one of the most puzzling conundrums of modern physics. Assuming that it stems from the existence of yet unknown dark matter (DM) particles, one can probe the cosmos in the hope of detecting unambiguo

Dissertation/ Thesis
Producing and constraining self-interacting hidden sector dark matter
Autor: Vanderheyden, Laurent
Les incompatibilités entre les simulations numériques, les prédictions théoriques et les observations cosmologiques à courtes et larges échelles suggèrent que la Matière Noire (MN) auto-interagit fortement. Il a été démontré qu’introdui

Searching for Light Dark Matter with a Spherical Proportional Counter
Autor: Knights, Patrick
Publikováno v: Instrumentation and Detectors [physics.ins-det]. Université Paris-Saclay; University of Birmingham (Royaume-Uni), 2021. English. ⟨NNT : 2021UPASP035⟩
Instrumentation and Detectors [physics.ins-det]. Université Paris-Saclay; University of Birmingham (GB), 2021. English. ⟨NNT : 2021UPASP035⟩
The NEWS-G collaboration is conducting experiments that search for dark matter down to sub-GeV candidate masses with a gaseous detector, the spherical proportional counter. The next-generation detector, SNOGLOBE, a 140 cm-diameter spherical proportio

Le côté obscur de la relativité générale
Autor: Coupechoux, Jean-Francois
Publikováno v: General Relativity and Quantum Cosmology [gr-qc]. Université de Lyon, 2021. English. ⟨NNT : 2021LYSE1153⟩
Motivated by the recent gravitational wave detections, we consider primordial black holes as a valid alternative to a significant fraction of dark matter. At the moment, there is no experimental evidence of such an object, but the event called GW1908

Recherche de matière noire légère avec les expériences DAMIC à SNOLAB et DAMIC-M : investigations de bruit de fonds radioactifs et sur les caméras CCD Skipper en silicium
Autor: Matalon, Ariel
The DAMIC (Dark Matter in CCDs) program employs the bulk silicon of scientific CCDs to search for ionization signals produced by interactions of particle dark matter, the nature of which is still unknown. By virtue of the low noise, low leakage curre

Tester la Relativité Générale avec des horloges dans l'espace, et explorer les possibilités de détection de matière noire avec des atomes froids dans l'espace et au sol
Autor: Savalle, Etienne
Publikováno v: Astrophysique [astro-ph]. Université Paris sciences et lettres, 2020. Français. ⟨NNT : 2020UPSLO014⟩
This thesis presents two research projects that are placed in the context of the two main theories of modern physics: general relativity and the standard model.— The first project aims at measuring the gravitational redshift between the PHARAO cloc
