HEAVY, BUT NOT METAL: Could Metal-Free Stars be the Source of Massive Black Hole Mergers?
In today’s paper, the authors test the theory that the earliest, metal-poorest stars are the primary source of binary black hole mergers.

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.
Relativistic Camels in space?? What a trip!
A new massive pulsar binary system has been found, but could it be an elusive double neutron star system?
How can tides help us find hidden compact companions and yield detailed physics on stellar binaries?
After more than 30 years, have astronomers finally discovered what the compact object at the center of Supernova 1987A is?
