UR: The Atomic Dark Matter Model: A Possible Solution to the Shortcomings of CDM

Could dark matter behave similarly to regular matter? If so, could dark matter halos collapse and form structures, like a black hole? In this work we explore the Atomic Dark Matter Model and predicting structure formation in it using simple algebra. We build on the current literature by showing that for certain values of the variables that govern dark matter interactions, we won’t be able to determine if the halo will be able to collapse using methods to track the dark matter number densities and how efficiently the halo can dispose of its initial energy.

Red Spirals

Red Spirals

JWST is currently revealing many previously unseen or undiscovered properties of our Universe. Even in the very first image released, three red spiral galaxies, which are super rare in our local Universe, can now be seen and analyzed down to structural details as never before. What can these weird galaxies tell us about the so-called cosmic noon and the evolution of galaxy formation?
