Early Universe

---

A new paper accepted for publication this month has highlighted how spiral galaxies came to form in the early Universe. By using the power of the Atacama Large Millimeter/submillimeter Array (ALMA), a team lead by Roberto Maiolino has individuated the mechanism through which galaxies gather stellar mass. For a star to form a certain amount of […]

We all get the munchies, but when you’re a supermassive black hole (SMBH) your hunger might have dire consequences. And just like that an SMBH has outgrown its galaxy and jumped to the top of the heavyweight objects in the universe.

About 12 billion light years from us, there is a galaxy called CID-947. It has a mass similar to our own Milky Way (about 1000 billion times the mass of the Sun) and it was only remarkable because it had an active galactic nucleus (AGN, i.e. an accreting SMBH).

Another important feature in the history of Universe are the proto-galaxies. In the last 30 years we were able to observe only a few dozen of these proto or primeval galaxies, which mostly looked like shapeless blobs with an intense UV emission.
