The massive relic galaxy NGC 1277 is dark matter deficient : From dynamical models of integral-field stellar kinematics out to five effective radii
- Abstract:
-
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 ~15% of the dynamical mass within one effective radius (1Re) and for ~60% within 5Re. Most massive ETGs have been shaped through a two-phase process: the rapid growth of a compact core was followed by...
