Astronomers have recently discovered a number of galaxies made almost entirely of dark matter. Today’s astrobite takes a closer look at one of them.
Dense star clusters gather around the centers of most galaxies. Where do they come from?
In the Triangulum Galaxy, over the course of a hundred thousand years, three supernova exploded from the same star cluster. The remains of these explosions have expanded into a trio of giant bubbles nested within each other.
The author revisits a seminal article that reviews our understanding of AGN feedback, and comes out extremely impressed with the status quo (and the parallels with fictional universes).
NGC 3115, also known as the Spindle galaxy, is the nearest example to us of a lenticular galaxy – a strange hybrid of the more common spiral and elliptical galaxy types. But how can we find out how such galaxies are made? The European Southern Observatory’s MUSE instrument sheds some light.
Today’s guest post from Nimisha Kumari looks at how different properties of galaxies can affect the Schmidt-Kennicutt Law.
