We compare the latest JWST deep observations with semi-analytic galaxy formation models. We observe a clear break in the slope of the number counts. This break is more pronounced at longer wavelengths. Since our model is able to reproduce this wavelength-dependent feature very well, we investigate how this could be related to the merging history of galaxies which in turn is sensitive to the...
The distribution of matter within dark matter halos contains key information about the nature and the properties of dark matter. Knowledge of the exact local dark matter density is not only important for cosmology, but also essential for precise calculations in both direct and indirect detection experiments. Getting the most out of the simulations from which the density profiles are inferred...
In a confining extension to the Standard Model, a stable composite particle could be a viable dark matter candidate. Often referred to as a strongly-interacting dark sector, such a theory along with a portal to the Standard Model can give rise to interesting semi-visible jet signatures at particle colliders. However, we still have a lot of work to do in improving our understanding of the...
Using a simplified mechanical-Lagrangian model we describe the gravitational waveform during the last seconds of the BNS merger phases in a dark matter environment. By considering
characteristic magnitudes for Neutron Stars from existing numerical simulations and magnitudes measurable during the BNS inspiral phase, i.e, chirp mass, mass ratio and distance we explore the effective parameter...
Direct dark matter detection experiments can reach the thresholds as low as O(10eV). In that regime, we report precision ionization measurements induced by Compton scattering of gamma rays and nuclear recoils from neutrons. A skipper charge-coupled device (CCD) with single electron resolution developed for DAMIC-M experiment was used to collect data. Compton scattering on sil- icon atomic...
The CYGNO collaboration aims to propose a large volume (O(30m^3)) gaseous Time Projection Chamber (TPC) with optical readout to search for rare events, such as interactions of DM in the GeV mass range and solar neutrinos. The TPC, operated with a He:CF4 gas mixture at atmospheric pressure, uses a triple Gas Electron Multiplier (GEM) stack to amplify primary ionization charges and produce...
Dark photons have been well motivated as strong candidates for dark force carriers and light dark matter in the sub-GeV mass range. Fixed-target experiments as a promising complementary approach to the collider could have good sensitivity in the low mass range. We would present the proposed study of Dark SHINE experiment searching for dark photon produced via electron-nucleon interaction and...
Global analyses of different dark matter searches are necessary to determine the status of dark matter models. Highly accurate antiproton measurements from AMS-02 would add valuable information to such global analyses. I will present an analysis pipeline for fast and accurate antiproton likelihoods in global scans. The pipeline consists of a neural network emulator for antiproton flux...
