Supermassive black holes (SMBHs; 10 6 –10 10 M ⊙) sit at the centres of massive galaxies and play a central role in galaxy evolution, yet their origin remains one of the most fundamental open ...

Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy’s visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot ...

New images from the Event Horizon Telescope (EHT) collaboration have revealed a dynamic environment with changing polarization patterns in the magnetic fields of the supermassive black hole M87*. As ...

Dwarf galaxies, with stellar masses below about 10^9–10^10 M⊙, offer unique laboratories for studying the earliest stages of black hole growth and the interplay between compact objects and shallow ...

An international team of astronomers has demonstrated a new technique that could revolutionize the way we observe some of the faintest black holes in the universe. By using a method called frequency ...

In the fall of 2002, scientists calculated the mass of a truly gargantuan entity at the heart of our Milky Way galaxy. It was four million times the mass of our Sun — so big it almost certainly had to ...

Astronomers have spotted the largest and most distant flare ever observed from a supermassive black hole. Nicknamed “Superman,” the flare originated 10 billion light-years from Earth, and at its peak, ...
