Galaxy observations and N-body cosmological simulations produce conflicting dark matter halo density profiles for galaxy central regions. While simulations suggest a cuspy and universal profile (UDP) of this region, the majority of observations favor variable profiles with a core in the center. We investigate the convergency of standard N-body simulations, especially in the cusp region. We...
The DarkSide program already produced leading results for both the low mass ($M_{WIMP}<10GeV/c^2$) and high mass ($M_{WIMP}>100GeV/c^2$) dark-matter direct-detection searches with its primary DarkSide-50 detector. Operating since 2013, DarkSide-50 was a 50-kg-active-mass dual-phase Liquid Argon Time Projection Chamber (TPC), filled with low radioactivity argon from an underground source. The...
Surveying the large-scale structure of the universe will yield an enormous amount of high quality data for constraining cosmology and potentially detecting new physics. However, extracting the maximum amount of information from this dataset and using it to its full potential requires fast and accurate methods of simulating cosmic structure formation in the nonlinear regime. Normally this is...
Understanding the effect of baryon-driven astrophysics on probes of large-scale structure is crucial to correctly interpret the increasingly precise data from ongoing surveys. The state-of-the-art cosmological hydrodynamic simulation, MillenniumTNG, represents a formidable tool in this respect. Combining a cosmologically representative volume of (740 cMpc)^3 and a mass resolution of ~3X10^7...
