Beating the confusion limit: The necessity of high angular resolution
  for probing the physics of Sagittarius A* and its environment: Opportunities
  for LINC-NIRVANA (LBT), GRAVITY (VLTI) and and METIS (E-ELT)
  The super-massive 4 million solar mass black hole (SMBH) SgrA* shows variable
emission from the millimeter to the X-ray domain. A detailed analysis of the
infrared light curves allows us to address the accretion phenomenon in a
statistical way. The analysis shows that the near-infrared flux density
excursions are dominated by a single state power law, with the low states of
SgrA* limited by confusion through the unresolved stellar background. We show
that for 8-10m class telescopes blending effects along the line of sight will
result in artificial compact star-like objects of 0.5-1 mJy that last for about
3-4 years. We discuss how the imaging capabilities of GRAVITY at the VLTI,
LINC-NIRVANA at the LBT and METIS at the E-ELT will contribute to the
investigation of the low variability states of SgrA*.
