The Event Horizon Telescope (EHT) Collaboration recently published the first images of the
supermassive black holes in the cores of the Messier 87 and Milky Way galaxies. These …

The cold dark-matter model successfully explains both the emergence and evolution of
cosmic structures on large scales and, when we include a cosmological constant, the …

We perform a comprehensive study of Milky Way (MW) satellite galaxies to constrain the
fundamental properties of dark matter (DM). This analysis fully incorporates inhomogeneities …

Unveiling the true nature of dark matter, which manifests itself only through gravity, is one of
the principal quests in physics. Leading candidates for dark matter are weakly interacting …

We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia
2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S 5). The …

In the fuzzy dark matter (FDM) model, gravitationally collapsed objects always consist of a
solitonic core located within a virialized halo. Although various numerical simulations have …

Gravitational weak lensing by dark matter haloes leads to a measurable imprint in the shear
correlation function of galaxies. Fuzzy dark matter (FDM), composed of ultralight axion-like …

The JWST early release data show unexpected high stellar mass densities of massive
galaxies at 7< z< 11. A high star formation efficiency is probably needed to explain this …

Analytic arguments and numerical simulations show that bosonic ultralight dark matter
(ULDM) would form cored density distributions (“solitons”) at the center of galaxies. ULDM …

In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive
substance that we call Dark Matter is hidden in the Universe and what is it made of? that …
