Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry
suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these …

Galaxy masses play a fundamental role in our understanding of structure formation models.
This review addresses the variety and reliability of mass estimators that pertain to stars, gas …

We present a detailed two-dimensional stellar dynamical analysis of a sample of 44
cosmological hydrodynamical simulations of individual central galaxies with stellar masses …

The evolution and distribution of the angular momentum of dark matter (DM) halos have
been discussed in several studies over the past decades. In particular, the idea arose that …

In order to understand the physical mechanisms at work during the formation of massive
early-type galaxies, we performed six zoomed hydrodynamical cosmological simulations of …

We investigate the internal structure of elliptical galaxies at z∼ 0.2 from a joint lensing–
dynamics analysis. We model Hubble Space Telescope images of a sample of 23 galaxy …

The light travel time differences in strong gravitational lensing systems allows an
independent determination of the Hubble constant. This method has been successfully …

Under the assumption of a flat ΛCDM cosmology, recent data from the Planck satellite point
toward a Hubble constant that is in tension with that measured by gravitational lens time …

We present optical and near-infrared spectroscopy obtained at Keck, Very Large Telescope,
and Gemini for a sample of 36 secure strong gravitational lens systems and 17 candidates …

We investigate the cosmic evolution of the internal structure of massive early-type galaxies
over half of the age of the universe. We perform a joint lensing and stellar dynamics analysis …
