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.
There’s a problem with dark matter, and two possible solutions: bright, luminous supernovae, or dark matter itself.
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!
Studying gravity on cosmological scales is HARD. Today’s papers build a framework to extend the standard cosmology toolbox, which means we can keep more of our data and learn more about gravity in the process.
Some things are really hard to observe, but we still can study them using computer simulations! Today’s paper will show you how people study planets-driven spiral arms!
How does a galaxy’s past impact its present day surroundings? Today’s authors use genetically modified simulations to investigate the effect of merger histories on stellar haloes.
