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?
Astronomers use cosmological simulations to better understand a funny sort of satellite galaxy.
Understanding the physics of a certain emission line will allow astronomers to study galaxies that existed a long time ago far, far away.
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.
A series of papers between two research groups, investigating the nature of an unusual distant galaxy.
