Guest: Novel Clues to the Formation of Ultra-Compact Dwarf Galaxies
In today’s bite, we look at some newly observed systems in the Virgo cluster. These observations provide clues to understanding how some of the most dense galaxies known to us form.
How to turn two galaxies into ten
A group of galaxies — some rich in dark matter, and some lacking dark matter completely — could be explained by a violent, destructive event from their past.
Uncovering black holes hiding in a globular cluster
A Milky way star cluster seems to contain more than the name suggests. How do astronomers find black holes hiding amongst stars?
Missing dark matter in a nearby dwarf galaxy
A satellite of Andromeda is missing an important ingredient — so where did it go?
Dwarfs from ELVES: The structure of dwarf satellite galaxies
How does the structure of the smallest galaxies vary with different environments? Today’s authors use the ELVES survey to investigate!
MARVEL + DC = Wandering Black Holes
