Stellar dynamics and stellar phenomena near a massive black hole
T Alexander - Annual Review of Astronomy and Astrophysics, 2017 - annualreviews.org
Most galactic nuclei harbor a massive black hole (MBH), whose birth and evolution are
closely linked to those of its host galaxy. The unique conditions near the MBH—high velocity …

Investigating the binarity of S0-2: Implications for its origins and robustness as a probe of the laws of gravity around a supermassive black hole
Abstract The star S0-2, which orbits the supermassive black hole (SMBH) in our Galaxy with
a period of 16 years, provides the strongest constraint on both the mass of the SMBH and …
