Abstract

Context.The supermassive black hole at the Galactic center, Sgr A*, shows frequent radiation outbursts, often called “flares”. In the near-infrared some of these flares were reported as showing intrinsic quasi-periodicities. The flux peaks associated with the quasi-periodic behavior were found to be highly polarized.
