The EDELWEISS collaboration performs light Dark Matter (DM) particle searches with high-purity germanium bolometers collecting both charge and phonon signals. Our recent results ([PhysRevD.106.062004][1]) using NbSi Transition Edge Sensor (TES) equipped detectors operated underground at the Laboratoire Souterrain de Modane (LSM) has shown the high relevance of this technology for future...
Almost a century ago, astrophysics observations lead to the suspicion of dark matter (DM) existence in gravitationally bound astrophysical objects such as our galaxy, the Milky Way. Since then, it became a pillar in modern cosmology. Yet, although many efforts were made to detect it, no DM signal have been observed in direct or indirect detection experiments.
There exists many candidates for...
L’expérience XENONnT est une expérience de détection directe de la matière noire utilisant une chambre à projection temporelle remplie de xénon liquide et gazeux. Elle a pour but principal de détecter la collision des WIMP avec les noyau de xénon. Les WIMP (Weakly Interacting Massive Particles) sont des particules théoriques candidates pour la matière noire. De part leur faible interaction...
Dark matter (DM) constitutes about 85% of the total matter content in the Universe and yet, we don’t know anything about its actual nature. In this talk, after an historical introduction, I will present my work on DM indirect detection, more especially the computation of X-ray constraints on sub-GeV (or “light”) DM. Photons from the galactic ambient bath see their energy boosted up to X-ray...
Since the first direct evidence of gravitational waves in 2015 the LIGO and Virgo collaboration have provided important results for astrophysics, cosmology or fundamental physics. The upgrades of the detectors through the years has increased the sensitivity and the range of detection, challenging their calibration. This talk reports the latest updates for a calibration method based on the...
