HST observations of gravitationally lensed QSOs
J. -F. Claeskens, D. Sluse, J. Surdej
Thanks to its sharp view, HST has significantly improved our knowledge of tens of gravitationally lensed quasars in four different respects: (1) confirming their lensed nature; (2)…
Spatial decomposition of on-nucleus spectra of quasar host galaxies
Knud Jahnke, Lutz Wisotzki, Frederic Courbin +1
In order to study the host galaxies of type 1 (broad-line) quasars, we present a semi-analytic modelling method to decompose the on-nucleus spectra of quasars into nuclear and host…
Lensing properties of 7 damped Lyman-alpha absorbing galaxy-QSO pairs
Vincent Le Brun, Alain Smette, Jean Surdej +1
Le Brun et al. (1997) presented the first identifications of the galaxies giving rise to 7 intermediate redshift damped Ly-alpha (DLA) absorption systems. Here, we study the gravit…
