The Trouble with Black Hole Wobbles
Today’s authors show that including nonlinear modes improves the black hole ringdown model and could be very important for gravitational wave data analysis.

Just before going supernova, some stars tend to have some gas problems, so why not simulate how?
What will JWST reveal about the obscured early Universe? Today’s authors process simulations to find out
How do neutron stars acquire such strong magnetic fields? Why do these fields differ between pulsars and magnetars? Today’s paper suggests that *convective dynamos* may be at play.
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.
We know that a cluster can be a dangerous place for a young star trying to form some new planets. Radiation and winds from massive stars can evaporate the planetary disc, and the gravitational pull from fly-bys of other stars can disrupt the disc and drag the planet-forming material away.
