Does modified gravity somehow explain galaxies that don't need it?

[user-000]

How do proponents of modified gravity explain the fact of observation of galaxies, the behaviour of matter in which does not require an explanation in the form of dark matter or modified gravity?

Which galaxies are you speaking of?

Which galaxies are you speaking of?

For example, one that mentioned here

and here

https://www.inverse.com/science/dark-matter-in-galaxies

the ones that behave as they have merely visible matter

NGC1277 is a lenticular galaxy, in between being rotationally and pressure supported. ΛCDM says those galaxies in general have a deficit of DM, and MOND says the acceleration is above the MOND turn-on. So both models say the same thing.

DF2 and DF4 are special, but a) AFAIK no other examples have been found, b) the interpretatiom depends on their distance, and c) there is some evidence that they are closer than supposed.

As a PS, popular articles tend to be substantially worse sources than the actual paper.
