Old and new stars paint very different pictures of the Triangulum galaxy

On Jan. 11 at the 241st meeting of the American Astronomical Society in Seattle, a team led by scientists at the �� and the Center for Computational Astrophysics reported something unexpected about the distinct populations of stars that make up the Triangulum galaxy: In this satellite galaxy, a close companion of the much larger Andromeda galaxy, old and new stars occur in separate parts of the galaxy's structure, something not seen in galaxies like our own and so far not reporter for other satellite galaxies.

Scientists find elusive gas from post-starburst galaxies hiding in plain sight

Scientists once thought that post-starburst galaxies scattered all of their gas and dust — the fuel required for creating new stars — in violent bursts of energy, and with extraordinary speed. Now, a team led by �� postdoctoral researcher Adam Smercina reports that these galaxies don’t scatter all of their star-forming fuel after all. Instead, after their supposed end, these dormant galaxies hold onto and compress large amounts of highly concentrated, turbulent gas. But contrary to expectation, they’re not using it to form stars.
