Diffuse radio emission from galaxy clusters
RJ Van Weeren, F de Gasperin, H Akamatsu… - Space Science …, 2019 - Springer
In a growing number of galaxy clusters diffuse extended radio sources have been found.
These sources are not directly associated with individual cluster galaxies. The radio …

Dark matter self-interactions and small scale structure
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 …

The nature of an ultra-faint galaxy in the cosmic dark ages seen with JWST
In the first billion years after the Big Bang, sources of ultraviolet (UV) photons are believed to
have ionized intergalactic hydrogen, rendering the Universe transparent to UV radiation …
