How have magnetic fields in galaxy clusters evolved throughout cosmic history, and what can these fields tell us about magnetism in the early Universe? Thanks to a few tricks from radio astronomy, today’s authors have some answers.
Galaxies in the middle of clusters are usually huge, elliptical galaxies. So what is this spiral-shaped imposter doing here?
Today’s authors use orbital measurements to dynamically “weigh” a group of galaxies. Read on to learn about this method and how the Centaurus A group may be missing some matter!
Active Galactic Nuclei are some of the brightest objects in the Universe. But what is responsible for switching on these supermassive engines?
How a new machine learning approach to generate synthetic Sunyaev-Zeldovich maps can help constrain cosmological physics.
Are past interactions to blame for the death of isolated, ultra-diffuse galaxies? Today’s authors use the IllustrisTNG simulations to find out.
