The combination of gravitational lensing and stellar dynamics breaks the mass-anisotropy degeneracy and provides stringent constraints on the distribution of luminous and dark matter in early-type (E/S0) galaxies out to z ≈ 1. We present new observations and models of three lens systems (CFRS 03.1077, HST 14176+5226, HST 15433+5352) and the combined results from the five field E/S0 lens galaxies at z ≈ 0.5-1.0 analyzed as part of the Lenses Structure and Dynamics (LSD) Survey. Our main results… 
Evidence for Dark Matter Contraction and a Salpeter Initial Mass Function in a Massive Early-type Galaxy
Stars and dark matter account for most of the mass of early-type galaxies, but uncertainties in the stellar population and the dark matter profile make it challenging to distinguish between the two
Gravitational Lensing & Stellar Dynamics: Dark-Matter and Baryons in Early-type Galaxies to z=1
Gravitational lensing and stellar dynamics provide two complementary, nearly orthogonal, constraints on the mass distribution of early-type lens galaxies. This allows the luminous and dark-matter
Evolution of central dark matter of early-type galaxies up to z ∼ 0.8
We investigate the evolution of dark and luminous matter in the central regions of early-type galaxies (ETGs) up to z � 0.8. We use a spectroscopically selected sample of 154 cluster and field

We study a sample of 39 massive early-type lens galaxies at redshift z ≲ 0.3 to determine the slope of the average dark-matter density profile in the innermost regions. We keep the strong-lensing and
DISENTANGLING BARYONS AND DARK MATTER IN THE SPIRAL GRAVITATIONAL LENS B1933+503
Measuring the relative mass contributions of luminous and dark matter in spiral galaxies is important for understanding their formation and evolution. The combination of a galaxy rotation curve and
Stars and dark matter in the spiral gravitational lens 2237+0305
We construct a mass model for the spiral lens galaxy 2237+ 0305, at redshift z(1) = 0.04, based on gravitational-lensing constraints, HI rotation, and new stellar-kinematic information, based on data
The Evolution and Structure of Early-Type Field Galaxies: A Combined Statistical Analysis of Gravitational Lenses
We introduce a framework for simultaneously investigating the structure and luminosity evolution of early-type gravitational lens galaxies. The method is based on the fundamental plane, which we
Dark matter distributions in early-type galaxies from strong gravitational lensing
Dark matter constitutes a large fraction of the mass of early–type galaxies. However, the exact amountand spatial distribution of the dark matter, especially in the galaxies’ center is still unclear.
