Monsters in miniature
Could intermediate-mass black hole activity resolve the long-standing problems with dwarf galaxies in cosmological simulations?
Meet the AAS Keynote Speakers: Dr. Ryan Hickox
This year, the Chandra X-ray Observatory is celebrating its 20-year legacy. Dr. Ryan Hickox of Dartmouth College will explain how the resulting discoveries have shaped our view of the high-energy universe in his plenary talk at #AAS233.
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.
