All Aboard the ARK(S Survey)!
The first set of high-resolution ALMA observations of exoKuiper belts has been released, and they reveal an unprecedented wealth of structure.
Should I Stay or Should I Go? Clumps and Inward Migration
Something is missing in the middle. In JWST JADES galaxies, young clumps drop out in the inner regions, while clump structure shifts from the outskirts to the center.
Where have all the AGN gone?
Astronomers think active black holes may play a role in shutting down star formation, but today’s study suggests that the story is more complicated than we thought.
Primordial Black Holes lensing my Andromeda Galaxy? It could be more common than you think
We’re not sure if Primordial Black Holes (PBHs) exist, but today’s authors might have seen evidence of them while observing the Andromeda Galaxy — and not just one PBH, but twelve!
When space plasmas collide!!
In today’s paper, our authors model what shenanigans will occur (or not?) when we slam two plasmas together!
Is that a galaxy-like star cluster? Or a cluster-like dwarf galaxy?
Compact ultra-faint systems? More like confusing ultra-faint systems!
