How did supermassive black holes grow in the early universe? Finding faint and distant AGN with JWST may help us unravel this mystery!
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!
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!
A strange tadpole molecular cloud seems to be swimming around an empty region in space.
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 ?
