Probing our Galaxy from the Center to the outskirts
Supermassive black holes — located in galactic nuclei— and dark matter —dominant in galactic halos— are vital ingredients in the cosmological process of galaxy formation, including that of our own Galaxy. However, probing our Galactic Centre (GC) and halo has proven observationally challenging. Hypervelocity stars (HVSs) are unique in that they deliver key information on both. Following interactions with black holes in the vicinity of Sagittarius A*, HVSs are ejected on fast trajectories through the halo. They thus bear testimony not only to the black hole and stellar populations within the hard-to-access innermost parsec, but also to the Galactic mass distribution, imprinted on their…
