Most Jupiter-like exoplanets go undetected. But do they leave a mark on the more easily detectable inner terrestrial worlds?
The key to understanding how these worlds are built is to consider where they are missing.
Observations from the MaNGA survey help to answer the question: What are the features of a galaxy that appears to have undergone recent gas accretion?
Do we really understand how black holes grow? Using new methods to run high resolution simulations, the authors of this paper investigate the evolution of gas near a supermassive black hole – and their results have serious implications for the models commonly used in cosmological simulations.
Some galaxies live peaceful lives, calmly making stars at a sedate pace, with supermassive black holes that don’t vomit jets of material. Other galaxies… not so much. Come to Professor Julie Comerford’s upcoming #AAS232 talk to learn more about the weird and wonderful world of active galactic nuclei!
LISA is a space-based mission to detect gravitational waves. What will be the brightest targets it can see?
