Thanks to data collected by NASA’s Chandra X-ray telescope on galaxies up to 3.5 billion light years away from Earth, an international team of astrophysicists was able to detect what is likely to be the most massive black holes ever discovered in the universe. The team’s calculations showed that these “ultramassive” black holes are growing faster than the stars in their respective galaxies.

In their search for black holes, the two lead authors of the article published in Monthly Notices of the Royal Astronomical Society – Julie Hlavacek-Larrondo, professor in the Department of Physics at Université de Montréal, and Mar Mezcua, postdoctoral fellow at the Institute of Space Sciences in Spain &#...
