“The discovery of the most massive stellar black hole in the Milky Way galaxy – A short essay about Stellar Black Holes and the methods used for their detection”

CLC’s team, led by Mr. Koutsoukos Spyros, BSc Physics Liverpool University, MA Applied Optics Imperial College London, Demokritos associate researcher, CLC’s Physics Teacher, mentored and supervised our students Alexandros Maravelis, Dimitris Karageorgiou, Dimitris Tzoannos and Konstantinos Alexopoulos, to carry out a research project on the most massive stellar black hole in the Milky Way galaxy.

This project highlights the discovery of the largest stellar black hole in the Milky Way, found by CNRS researchers under Pasquale Panuzzo, with a mass 33 times that of the Sun and located just 1900 light-years away. The study explores black hole types, from the elusive primordial black holes to supermassive ones at galactic centers, detailing how these mysterious objects form and evolve. It also investigates black hole anatomy, such as event horizons and singularities, and explains why it is so challenging to detect. Finally, it reviews current detection techniques, including gravitational wave analysis and X-ray observations, to illuminate our understanding of these cosmic giants.
