Hunting For "Wandering" Black Holes In Dwarf Galaxies

Universe Today - Wed, 11/19/2025 - 8:13am

Tracking down black holes at the center of dwarf galaxies has proven difficult. In part that is because they have a tendency to “wander” and are not located at the galaxy’s center. There are plenty of galaxies that might contain such a black hole, but so far we’ve had insufficient data to confirm their existence. A new paper from Megan Sturm of Montana State University and her colleagues analyzed additional data from Chandra and Hubble on a set of 12 potential Active Galactic Nuclei (AGN) galaxy candidates. They were only able to confirm three, which highlights the difficulty in isolating these massive wanderers.

Webb spots greedy supermassive black hole in early Universe

ESO Top News - Wed, 11/19/2025 - 6:00am

Researchers using the NASA/ESA/CSA James Webb Space Telescope have confirmed an actively growing supermassive black hole within a galaxy just 570 million years after the Big Bang. Part of a class of small, very distant galaxies that have mystified astronomers, CANUCS-LRD-z8.6 represents a vital piece of this puzzle and challenges existing theories about the formation of galaxies and black holes in the early Universe. The discovery connects early black holes with the luminous quasars we observe today.
