Could Quasar Lensing Time Delays Hint to a Core Component in Halos, Instead of $H_0$ Tension?
The time delay measured between the images of gravitationally lensed quasars probes a combination of the angular diameter distance to the source-lens system and the mass density profile of the lens. Observational campaigns to measure such systems have reported a determination of the Hubble parameter...
