Exploring the gravitationally lensed system HE1104-1805: VLT spectroscopy of the lens at z=0.729
C. Lidman, F. Courbin, J. -P. Kneib +3
Using FORS2, mounted on Kueyen (UT2 of the VLT), we have obtained the redshift of the lensing galaxy in the gravitational lens system HE1104-1805. We measure z=0.729, in good agree…

Confidence levels of evolutionary synthesis models
M. Cervino, V. Luridiana, F. J. Castander
The stochastic nature of the IMF in young stellar clusters implies that clusters of the same mass and age do not present the same unique values of their observed parameters. Instea…
