The massive relic galaxy NGC 1277 is dark matter deficient : From dynamical models of integral-field stellar kinematics out to five effective radii
According to the Λ cold dark matter (Λ CDM) cosmology, present-day galaxies with stellar masses M∗>1011M⊙ should contain a sizable fraction of dark matter within their stellar body. Models indicate that in massive early-type galaxies (ETGs) with M∗≈1.5 × 1011M⊙, dark matter should account for...
