A few hundreds of thousands of years after the Big Bang, the first galaxies formed. These galaxies were unique - relatively small in size but with central supermassive black holes significantly larger than what we see in present day galaxies. Over time, most of these galaxies merged with other galaxies and lost these unique attributes. However, a very small number managed to stay untouched until the present day: almost 13 billion years. These rare fossils of the early universe are called relic galaxies, and to date only a very small handful have been found. There is a big push in astrophysics to find more, as they can help us understand the infancy of our universe.
