Many assumptions are used as input for photoionization codes that model HII regions. Today’s paper explores how these assumptions are oversimplified and emphasizes the need for more physically realistic ones.
Today’s authors serendipitously discovered a new celestial beast lurking in the Magellanic Clouds—what could it be?
Today’s paper looks at the gravitational influence of the Large Magellanic Cloud on the Milky Way – one may think our Galaxy is in equilibrium, but it is actually being sloshed around!
The formation of the Magellanic stream is a decades long mystery that might have been solved by considering corona. No, not that corona. . .
Four new Milky Way dwarf satellite candidates were discovered in 2015 using the Dark Energy Survey. Fainter imaging data are used to further investigate their exact nature.
Orbiting our galaxy are many smaller dwarf galaxies. As they orbit, some of these galaxies produce vast streams of gas that stretch around our Milky Way galaxy. Much of this gas still has the potential for forming stars. This astrobite will summarize a recent discovery of one of these stars.
