The universe's biggest galaxies have both vast atmospheres and supermassive central
black holes. This article reviews how those two components of a large galaxy couple and …

We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

We present an overview of scenarios where the observed Dark Matter (DM) abundance
consists of Feebly Interacting Massive Particles (FIMPs), produced nonthermally by the so …

To avoid the complex process of explicit feature extraction in traditional facial expression
recognition, a face expression recognition method based on a convolutional neural network …

We present the first simulations within an effective theory of structure formation (ETHOS),
which includes the effect of interactions between dark matter and dark radiation on the linear …

Using three-dimensional simulations, we study the dynamics and final structure of merging
solitonic cores predicted to form in ultralight axion dark matter halos. The classical …

We perform numerical simulations of the merging galaxy cluster 1E 0657-56 (the Bullet
Cluster), including the effects of elastic dark matter scattering. In a similar manner to the …

The nature of dark matter is one of the most pressing questions in physics. Yet all our
present knowledge of the dark sector to date comes from its gravitational interactions with …

Gravitational lensing by clusters of galaxies offers a powerful probe of their structure and
mass distribution. Several research groups have developed techniques independently to …

The majority of the matter in the universe is still unidentified and under investigation by both
direct and indirect means. Many experiments searching for the recoil of dark-matter particles …
