Integral field spectroscopy of four lensed quasars: analysis of their neighborhood and evidence for microlensing
T. Anguita, C. Faure, A. Yonehara +4
CONTEXT: Gravitationally lensed quasars constitute an independent tool to derive H0 through time-delays; they offer as well the opportunity to study the mass distribution and inter…
COSMOS 5921+0638: Characterization and analysis of a new strong gravitationally lensed AGN
T. Anguita, C. Faure, J. -P. Kneib +4
[abridged] We present VLT/FORS1 spectroscopic follow-up observations and HST/WFPC2 imaging of the system COSMOS 5921+0638, which exhibits quadruply lensed images and a perfect Eins…
A seven square degrees survey for galaxy-scale gravitational lenses with the HST imaging archive
R. S. Pawase, C. Faure, F. Courbin +2
We present the results of a visual search for galaxy-scale gravitational lenses in nearly 7 square degrees of Hubble Space Telescope (HST) images. The dataset comprises the whole i…
VLT adaptive optics search for luminous substructures in the lens galaxy towards SDSS J0924+0219
C. Faure, D. Sluse, N. Cantale +4
Anomalous flux ratios between quasar images are suspected to be caused by substructures in lens galaxies. We present new deep and high resolution H and Ks imaging of the strongly l…
The RAdial Velocity Experiment (RAVE): Fourth data release
G. Kordopatis, G. Gilmore, M. Steinmetz +48
We present the stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, individual abundances and distances determined for 4…
The properties of the local spiral arms from RAVE data: two-dimensional density wave approach
A. Siebert, B. Famaey, J. Binney +19
Using the RAVE survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely origina…
