The Hidden Mechanism of Quasar Feedback
Galactic winds shed new light on an otherwise invisible mechanism at the heart of massive galaxies.

Could a suspicious pair of active black holes improve the outlook for seeing the gravitational wave background?
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.
A ghostly plasma lens occulting QSR J1819+3845 has been imaged directly at radio wavelengths. What can we learn about this strange interloper? (Image: unrelated observation of solar activity resembling a jack-o’-lantern, courtesy NASA/GSFC/SDO)
Many dark galaxies may be hiding unseen in the universe—but we still might be able to detect them. Here’s how.
Supermassive black holes are among the most exciting objects in the universe. Even more so, when they dance around each other after the merger of two galaxies.
