The stellar initial mass function and dark matter halo of ESO0286: Constraints from strong lensing and dynamics
The internal mass structure of elliptical galaxies offers critical insights into galaxy formation, yet disentangling stellar mass from dark matter (DM) and determining the stellar initial mass function (IMF) remain challenging. We present a detailed analysis of ESO0286-G022 (z=0.0312), a rare nearby strong-lens system...
