Similar types of objects have been found in the more local, present-day Universe, such as Arp 299 shown here. This is something others have been predicting for a few years now, and it's really nice to see the first direct observational evidence supporting this scenario." Ryan Endsley, the lead author of the paper and now a Postdoctoral Fellow at The University of Texas at Austin, says "These results suggest that very early supermassive black holes were often heavily obscured by dust, perhaps as a consequence of the intense star formation activity in their host galaxies. The problem is that most such black-hole pairs are too close together to distinguish individually. The surprising discovery of COS-87259 and its black hole raises several questions about the abundance of very early supermassive black holes, as well as the types of galaxies in which they typically form.

These quasars are extremely rare at distances similar to COS-87259, with only a few tens located over the full sky. The only other class of supermassive black holes we knew about in the very early Universe are quasars, which are active black holes that are relatively unobscured by cosmic dust. This was completely unexpected from previous data.

What is particularly astonishing about this new object is that it was identified over a relatively small patch of the sky typically used to detect similar objects - less than 10 times the size of the full moon - suggesting there could be thousands of similar sources in the very early Universe. Because the light from these sources takes so long to reach us, we see them as they existed in the past in this case, just 750 million years after the Big Bang, which is approximately 5% of the current age of the Universe. How these supermassive black holes first formed remains a mystery for scientists, particularly because several of these objects have been found when the Universe was very young. Today, black holes with masses millions to billions of times greater than that of our own Sun sit at the centre of nearly every galaxy. The researchers have also found that this growing supermassive black hole (frequently referred to as an active galactic nucleus) is generating a strong jet of material moving at near light speed through the host galaxy. The black hole is considered to be a new type of primordial black hole - one heavily enshrouded by cosmic "dust," causing nearly all of its light to be emitted in the mid-infrared range of the electromagnetic spectrum. The galaxy shines bright from both this intense burst of star formation and the growing supermassive black hole at its centre.

This orbital offset canīe sustained for up to at least 6 Gyr between $z=2$ and $z=0$ in half of ourīCGs.Using observations taken with the Atacama Large Millimeter Array (ALMA), a radio observatory sited in Chile, the team have determined that the galaxy, named COS-87259, containing this new supermassive black hole is very extreme, forming stars at a rate 1000 times that of our own Milky Way and containing over a billion solar masses worth of interstellar dust. Precisely a third of our BHs are off-centred at $z=0$.

Results clearly establish that SMBH offsets are common in BCGs and more To distances varying between a few parsecs to hundreds of kiloparsecs.
