Some Black Holes Grow Much Faster Than Their Galaxies

• Some black holes grow much faster than their galaxies, as evidenced by a study of over 20,000 quasars. The research found eight quasars with black hole masses that are 20 to 1 compared to their galaxy masses, meaning the black holes account for about 5% of the galaxy's mass. These black holes are consuming matter at an exceptional pace and could double in mass in a billion years.
• The study highlights a potential mechanism where black hole growth can outstrip galaxy growth, even though there is a general connection between them. The galaxies hosting these black holes are faint and may not contain as many stars as the Milky Way. The exact reason for this discrepancy remains unclear, but more observations are needed to determine the underlying process.
