Traits of Accreting Galaxies
Observations from the MaNGA survey help to answer the question: What are the features of a galaxy that appears to have undergone recent gas accretion?
Understanding Dwarf Galaxies with a Heart of Steel
Hydrodynamical simulations shed new light on the metallicity of stellar populations in dwarf galaxies.
How to Diagnose the Light from Early Galaxies
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
How the Milky Way Got its Spiral Arms
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.
Going Against the Galactic Flow
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.
The strange case of quiescent and dusty
A series of papers between two research groups, investigating the nature of an unusual distant galaxy.
