Irregular Clocks: The Influences of Generous Companions
Pulsars, or rapidly-spinning neutron stars, have been observed to suddenly change in spin. Typically, the pulsars we’ve seen do this are isolated—what happens if they have a stellar companion?

The Milky Way grew by accreting many smaller galaxies. What did these doomed galaxies leave behind, and what could they say about the Milky Way’s early past?
New 3D simulations that capture the last minutes of a massive star’s life reveal that its violently turbulent interior can affect how it dies.
The rare (un)lucky star dies by means of black hole, which shreds the star to bits before swallowing it. It’s a spectacular death to observe, but one which is less bright and hot than we thought they would be…
Dwarf galaxies have long been vaunted a useful probe for dark matter physics due to their high dark matter content. But is this true for all dwarfs, particularly the smallest ones? And can the minority baryons affect dark matter signatures?
