An international team of researchers, led by postgraduate student Alexis Andrés, has found that the black hole at the center of our galaxy, Sagittarius A*, not only flares irregularly from day to day but also in the long term. The team analyzed 15 years’ worth of data to come to this conclusion. The research was initiated by Andres in 2019 when he was a summer student at the University of Amsterdam. In the years that followed, he continued his research, which is now to be published in Monthly Notices of the Royal Astronomical Society.
