Gravitational Lensing & Stellar Dynamics: Dark-Matter and Baryons in Early-type Galaxies to z=1
L. V. E. Koopmans
Gravitational lensing and stellar dynamics provide two complementary, nearly orthogonal, constraints on the mass distribution of early-type lens galaxies. This allows the luminous…
The dark matter halos of spheroidal galaxies and clusters of galaxies
T. Treu, L. V. E. Koopmans, D. J. Sand +2
We describe the first results from two observational projects aimed at measuring the amount and spatial distribution of dark matter in distant early-type galaxies (E/S0s) and clust…
B0850+054: a new gravitational lens system from CLASS
A. D. Biggs, D. Rusin, I. W. A. Browne +12
We report the discovery of a new gravitational lens system from the CLASS survey. Radio observations with the VLA, the WSRT and MERLIN show that the radio source B0850+054 is compr…
Probing dark matter distribution with gravitational lensing and stellar dynamics
T. Treu, L. V. E. Koopmans
The Lenses Structure and Dynamics (LSD) Survey aims at measuring the luminous and dark matter distribution of high redshift early-type galaxies by combining gravitational lens anal…
The Kinematics of High Proper Motion Halo White Dwarfs
L. V. E. Koopmans, R. D. Blandford
We analyse the kinematics of the entire spectroscopic sample of 99 recently discovered high proper-motion white dwarfs by Oppenheimer et al. using a maximum-likelihood analysis, an…
Compact Objects and Accretion Disks
Roger Blandford, Eric Agol, Avery Broderick +3
Recent developments in the spectropolarimetric study of compact objects, specifically black holes (stellar and massive) and neutron stars are reviewed. The lectures are organized a…
