The galaxies you see at the blue blob are far beyond the galaxy that is analyzed here.

They have no gravitational effect on it. However, the light from those galaxies is gravitationally lensed by the mass of the "blue blob". That is how the "blue blob" mass is detected/inferred/measured. We do not actually see much of anything in the spectrum we have searched at that location [or to be more accurate, we do not see anything that can account for the magnitude of the gravitational lensing we see]. Hence the gravitational lensing is caused by dark matter.
