The Galactic center as a research area focuses on the physical conditions, dynamics, and energetic processes in the central few hundred parsecs of the Milky Way, encompassing the supermassive black hole Sagittarius A*, dense stellar clusters, molecular clouds, and non-thermal emission regions. Studies integrate multiwavelength observations (radio to gamma rays) with numerical simulations to probe accretion physics, star formation under extreme tidal and radiation fields, cosmic-ray acceleration, and feedback-driven outflows. This domain also addresses gravitational potential mapping, stellar kinematics, magnetohydrodynamics of the interstellar medium, and tests of general relativity in the strong-field regime, making it a key laboratory for understanding galactic nuclei in general.
New observations and simulations by a team of researchers led by MPE reveal that a massive binary star near our galaxy's center is responsible for creating a series of enigmatic gas clouds—compact gas clumps that help feed ...

The center of our galaxy is an extreme place. Surrounding the supermassive black hole Sagittarius A*, stars are packed densely into a region where gravity, radiation, and dark matter all interact in complex ways. It is a ...
Supermassive black holes at the centers of galaxies are one of the most active fields of research in astronomy. In order to accumulate their enormous masses, they must merge with each other. A research team led by Silke Britzen ...
