The apparent tail of the Galactic center object G2/DSO
  The observations of the near-infrared excess object G2/DSO induced an
increased attention towards the Galactic center and its vicinity. The predicted
flaring event in 2014 and the outcome of the intense monitoring of the
supermassive black hole in the center of our Galaxy did not fulfill all
predictions about a significantly enhanced accretion event. Subsequent
observations furthermore addressed the question concerning the nature of the
object because of its compact shape, especially during its periapse in 2014.
Theoretical approaches have attempted to answer the contradicting behavior of
the object, resisting the expected dissolution of a gaseous cloud due to tidal
forces in combination with evaporation and hydrodynamical instabilities.
However, assuming that the object is rather a dust-enshrouded young stellar
object seems to be in line with the predictions of several groups and
observations presented in numerous publications. Here we present a detailed
overview and analysis of the observations of the object that have been
performed with SINFONI (VLT) and provide a comprehensive approach to clarify
the nature of G2/DSO. We show that the tail emission consists of two isolated
and compact sources with different orbital elements for each source rather than
an extended and stretched component as it appeared in previous representations
of the same data. Considering our recent publications, we propose that the
monitored dust-enshrouded objects are remnants of a dissolved young stellar
cluster whose formation was initiated in the Circum-nuclear Disk. This
indicates a shared history which agrees with our analysis of the D- and
X-sources.
