The discovery of a second dark matter deficient galaxy by van Dokkum et al. has caused the debate on galaxies lacking dark matter to resurface.
Hydrodynamical simulations shed new light on the metallicity of stellar populations in dwarf galaxies.
The spiral arms of galaxies are among the most recognizable galactic features, yet we still know little about their precise formation mechanism. Today’s paper leverages new data from the Gaia mission to test some of the leading theories.
