Making a Splash
Today’s paper takes a closer look at the after-effects of the Milky Way’s last major collision with another galaxy.
Inconstant, Fine Structures
Using simulations of a Milky Way-sized elliptical galaxy, astronomers study how stellar substructures can tell us about past merger events.
Is the Milky Way Gaining or Losing Mass?
Today’s paper analyzes the inflow and outflow rates of gas in the Milky Way, allowing us to better understand how the galaxy interacts with its surroundings.
Dwarf Galaxies without Dark Matter
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
Galaxy collisions and star-formation: a surprising causal examination
The longstanding role of galaxy mergers as drivers of star-formation is brought into question
With Age Comes Wisdom
By determining the precise ages of stars in our galaxy, today’s Astrobite focuses on piecing together a detailed history of our own Milky Way.
