Massive galaxies all seem to end up quiet and quenched—but the physics inside them can look wildly different. This story explores how AGN-driven cosmic rays reshape galaxies from the inside out, changing local conditions without altering their ultimate fate.
Half of all stars are in binaries. Stars that end their lives as the most massive white dwarfs often also have another distant star orbiting an inner binary. Could these tertiary stars play a role in merging the inner binaries into remnant objects that emit fast radio bursts?
Cosmic rays don’t always reveal their origins honestly—magnetic fields can bend their paths and create “mirage halos” that look like real gamma-ray sources. New simulations show how a single pulsar can masquerade as three, reshaping how we interpret TeV observations.
Neutron stars are some of the densest, most exotic objects in the universe. Today’s paper explores how simulating novel neutrino physics affects the outcome of neutron star mergers.
In 2022, NASA’s DART spacecraft crashed itself into an asteroid in a binary system. Today’s paper investigates the unexpected evolution of the binary’s orbit after the collision.
Though moons are ubiquitous in our Solar System, we have not yet found one elsewhere (an exomoon). Today’s paper investigates whether we could find moons by precisely tracking the positions of a star and planet.
