If we explore this interesting image (see above) and the correlated text, we seem to miss any trail of a central giant black hole lurking.
HOW CAN?
WE CAN, IF WE CHANGE OUR STANDARD MODEL and ideas A LITTLE BIT.
SEE:
The only visible trails are two elliptic grey filaments which could be the tell tails of two medium sized black holes, just as is suggested to be the origin of the other elliptic filaments visible around the two other open star clusters. (called Quintuplet and Arches cluster)
NO GIANT black hole inside the Galaxy center?
The mainstream ideas about a Giant Milky way- central black hole are lately firmly supported by clear stellar acceleration profiles around the Sagittarius A cluster, see:
http://www.einstein-online.info/en/spotlights/milkyway_bh/index.htmlHowever according to new combined Hubble images of the Sgt..A area there is no sign of any gaseous filamentary Vortex or elliptic structure.
Instead we see more than one clear elliptic filaments around the three stellar clusters called: Sagittarius A, Quintuplet and Arches cluster.
This seems to be a tell tale for more than one (at least three) barycentres as the origin of these open star clusters.
My conclusion based on a new interpretation of black hole splitting and paring
The center of the Milky way is supposed to be equipped with several medium sized DUAL black holes (BHs) forming circular visible gas filaments (elliptic trails) and in the barycenter in the middle between dual black holes: open star clusters like Sgt A, the Quintuplet and Arches cluster. Conclusion: there is NO Giant Black hole in the center of our galaxy.

Explanation: What's happening at the center of our Milky Way Galaxy? To help find out, the orbiting
Hubble and
Spitzer space telescopes have combined their efforts to
survey the region in unprecedented detail in infrared light.
Infrared light is particularly useful for probing the
Milky Way's center because visible light is more greatly obscured by
dust. The
above image encompasses over 2,000 images from the
Hubble Space Telescope's
NICMOS taken last year. The image spans 300 by 115 light years with such
high resolution that structures only 20 times the size of our own Solar System are discernable. Clouds of glowing gas and
dark dust as well as three large star clusters are visible.
Magnetic fields may be channeling
plasma along the upper left near the
Arches Cluster, while energetic
stellar winds are carving
pillars near the
Quintuplet Cluster on the lower left. The massive Central Cluster of stars surrounding
Sagittarius A* is visible on the lower right. Why several central, bright, massive stars appear to be unassociated with
these star clusters is not yet understood.
This description "NOT YET UNDERSTOOD" is in sharp contrast with former releases of the ESA study of 16 years on the center of the Galaxy, presented earlier, talking about the proof of the giant lurking black hole inside the Sagitarius complex see:
