Polarized NIR observations of Sagittarius A*

We report on recent near-infrared observations of the super massive black hole at the Galactic Center (GC), Sagittarius A*.The observations have been carried out using the NACO adaptive optics instrument at the European Southern Observatory's Very Large Telescope on 17th May 2012.The polarization measurements of Sagittarius A* for these data sets show that its emission is polarized during its frequent radiation outbursts.The high level of linear polarization at 2.2 micron and its strong variations can provide clues to constrain the physical conditions of the accretion flow around this SMBH.We are going to combine these data sets with the data simultaneously taken by other telescopes from the X-ray to radio regime.This multiwavelength study will help us reveal the origin of the emission detected from Sagittarius A*.
