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 (ΛCDM) cosmology, present-day galaxies with stellar

A Self-interacting Dark Matter Solution to the Extreme Diversity of Low-mass Halo Properties
The properties of low-mass dark matter (DM) halos appear to be remarkably diverse relative
to cold, collisionless DM predictions, even in the presence of baryons. We show that self …

The odd dark matter halos of isolated gas-rich ultradiffuse galaxies
We analyze circular velocity profiles of seven ultradiffuse galaxies (UDGs) that are isolated
and gas-rich. Assuming that the dark matter halos of these UDGs have a Navarro–Frenk …
