How to Un-squash a Galaxy
Does our galaxy look like an Advil, a NyQuil, or just a simple sphere? The simulations studied in today’s paper may have the answer.
Plenty of Gas Left in Giant Dead Disk Galaxies
New findings suggest that they have a lot of gas – but then why are they not forming stars?
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.
