Spiral Galaxies Show Their Metal
Nearby spiral galaxies aren’t metalheads, but they might have lots of metals in their arms.
Meet the AAS Keynote Speakers: Julie Comerford
Some galaxies live peaceful lives, calmly making stars at a sedate pace, with supermassive black holes that don’t vomit jets of material. Other galaxies… not so much. Come to Professor Julie Comerford’s upcoming #AAS232 talk to learn more about the weird and wonderful world of active galactic nuclei!
Snake (on a Plane) in the Clouds
A report on the characteristics of a new ultra-faint dwarf found in the Magellanic Bridge, in the constellation Hydrus.
Same time, same place: pinpointing star formation in distant active galaxies
Using super high resolution data from ALMA and the VLA, the authors of this paper resolve star formation in active galaxies — and find that active galactic nuclei are embedded inside central star-forming regions.
Fantastic tidal features and where to find them
Some of the most interesting structures on galactic scales are formed via tidal interactions. Today’s paper arrives at some unexpected conclusions about which types of galaxies are most likely to host such tidal features.
One Magnified Starburst Galaxy
Astronomers study a gravitationally lensed emission line galaxy, with implications for the characteristics of early galaxy populations.
