Galaxy structure with strong gravitational lensing: decomposing the internal mass distribution of massive elliptical galaxies
James. W. Nightingale, Richard J. Massey, David R. Harvey +4
We investigate how strong gravitational lensing can test contemporary models of massive elliptical (ME) galaxy formation, by combining a traditional decomposition of their visible…
