How did Lindsay Lohan and Arnold Schwarzenegger find their way into a bite about binary stars? Read on to find out.
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.
An intriguing subset of galaxies exhibit counter-rotating components, that go against the flow of the majority of the stars. Today’s paper examines two such galaxies and reaches a different conclusion about each of them.
Stellar streams are an excellent tool for probing the nature of Dark Matter. Today’s paper tests whether Fuzzy Dark Matter is a viable theory by evaluating the thinness of streams in the Milky Way.
