Ultramassive black hole discovered at center of Cosmic Horseshoe

A massive black hole has been identified at the center of a colossal galaxy.

Discovery of Ultrafast Black Hole Shakes Understanding of Galaxy Formation

Astronomers have announced the discovery of an ultramassive black hole located in the Cosmic Horseshoe galaxy, which is about 36.3 billion times the mass of the Sun. This black hole, identified as possibly the heaviest ever discovered, is positioned in a galaxy that distorts light significantly due to its immense gravity. Unlike previous claims of massive black holes whose estimates often come with considerable uncertainty, this measurement uses a new method that yielded more reliable results. The study indicates that this black hole and its host galaxy have evolved together, hinting at crucial insights into the nature of supermassive black holes and their interactions with galaxies over time. The research was published in the Monthly Notices of the Royal Astronomical Society.

The discovery of this ultramassive black hole alters the landscape of astrophysics, as it challenges previously held notions regarding the formation and evolution of galaxies. Understanding that black holes can exist in silent states expands the potential for future observations. Carlos Melo, the lead author, emphasizes the significance of this finding not only in terms of mass measurement but also in revealing how black holes can merge and grow over cosmic time. This discovery suggests that the relationships between galaxies and black holes are more complex than previously understood. It marks a significant step toward unveiling the mysteries of the universe and our place within it.
