| Abstract: |
Our goal is to investigate and understand the
physical processes behind the variability associated with the NIR
flaring emission from Sagittarius A* (Sgr A*).
We found a correlation between the modulations of the observed
flux density light curves and changes in polarimetric data.
Correlations between intensity and
polarimetric parameters of the observed light curves as well as a
comparison of predicted and observed light curve features through a
panttern recognition algorithm resulted in the detection of a signature
of orbiting matter under the influence of strong gravity. This
pattern is detected statistically significant against randomly
polarized red noise. |
