Emulating Galaxy Clusters
How a new machine learning approach to generate synthetic Sunyaev-Zeldovich maps can help constrain cosmological physics.
Baby B-fields from the Big Bang and Beyond
Cosmic magnetic fields are everywhere, but we don’t know where they came from. Today’s paper looks at simulations of the earliest fields in the Universe to try to solve this magnetic mystery.
Exploring the Invisible Milky Way
Today’s paper looks at our own galaxy to measure its dark matter halo mass.
The Search for a Ninth Planet in the Solar System (No, it’s still not Pluto, sorry.)
Is there a ninth planet in the solar system? Today’s paper examines the orbital clustering of some Kuiper belt objects and where the planet causing these gravitational perturbations may be found.
A story of light and darkness
There’s a problem with dark matter, and two possible solutions: bright, luminous supernovae, or dark matter itself.
Self-Interacting Dark Matter: A Better Destroyer of Galaxies
When galaxies fall into galaxy clusters, the consequences can be quite epic. But are they more epic with Self-Interacting Dark Matter? Today’s paper suggests the answer is yes. Bite also available in Dutch / Deze Bite is ook beschikbaar in het Nederlands!
