Can we identify the host galaxies of LISA sources?
The upcoming LISA mission promises to detect many gravitational wave events, but can it attribute any of them to a host galaxy? Let’s find out!
Tracing Star Fuel in the Universe’s Smallest Galaxies
It’s really hard to see molecular hydrogen (the fuel that makes stars) directly, so astronomers have to use other spectral lines to guess how much is there. In today’s paper, the authors discuss how to do that in the smallest galaxies in the universe!
Tadpole Swimming in a Gravitational Whirlpool
A strange tadpole molecular cloud seems to be swimming around an empty region in space.
Twinkle twinkle trail of stars, how I wonder what you are?
What are the origins of this mysterious stellar streak ? Could it be a wake left behind by a rogue black hole or something else entirely ?
Colossal collisions and how they’ve shaped the Milky Way
In today’s paper, astronomers show how massive collisions have shaped some of the properties of galaxies over time, giving insight into the formation of our own Milky Way.
Galactic Tails tell Galactic Tales – and this one is a Strange Tail Indeed
Today’s authors discovered a very long, very odd galactic tail, and discuss what that means for its origin and for the history of the galax(ies) involved!
