Adaptive optics imaging of low and intermediate redshift quasars
I. Marquez, P. Petitjean, B. Theodore +3
We present the results of adaptive-optics imaging in the H and K bands of 12 low and intermediate redshift (z<0.6) quasars using the PUEO system mounted on the Canada-France-Hawaii…
Adaptive optics imaging and integral field spectroscopy of APM 08279+5255: Evidence for gravitational lensing
C. Ledoux, B. Theodore, P. Petitjean +5
We report observations of the z = 3.87 broad absorption line quasar APM 08279+5255 (Irwin et al. 1998) with the Adaptive Optics Bonnette (AOB) of the Canada-France-Hawaii Telescope…
A damped Ly-alpha candidate at z~0.1 toward Q 0439-433
Patrick Petitjean, Bertrand Theodore, Alain Smette +1
We report on the detection of a z_gal=0.101 galaxy projected on the sky at 4.2 arcsec (or 5.2 h^{-1} kpc for q_o=0.5) from the quasar Q 0439-433 (z_em=0.594). The HST spectrum of t…
