ZEN and the search for high-redshift galaxies
J. P. Willis, F. Courbin, J-P. Kneib +1
We present the ZEN (z equals nine) survey: a deep, narrow J-band search for proto-galactic Lya emission at redshifts z=9. In the first phase of the survey, dubbed ZEN1, we combine…
Discovery of a bright quasar without a massive host galaxy
Pierre Magain, Geraldine Letawe, Frederic Courbin +4
Quasars are thought to be powered by the infall of matter onto a supermassive black hole at the centre of massive galaxies. As the optical luminosity of quasars exceeds that of the…
Quasar Lensing: the Observer's Point of View
F. Courbin
The determination of the Hubble parameter H_0 is probably one of the most important applications of quasar lensing. The method, based on the measurement of the so-called ``time-del…
Quasar Lensing
F. Courbin, P. Saha, P. L. Schechter
Massive structures, such as galaxies, act as strong gravitational lenses on background sources. When the background source is a quasar, several lensed images are seen, as magnified…
Exploring the gravitationally lensed system HE 1104-1805: Near-IR Spectroscopy
F. Courbin, C. Lidman, G. Meylan +2
(Abridged) A new technique for the spatial deconvolution of spectra is applied to near-IR (0.95 - 2.50 micron) NTT/SOFI spectra of the lensed, radio-quiet quasar HE 1104-1805. The…
Resolved Stellar Populations of Super-Metal-Rich Star Clusters in the Bulge of M31
P. Jablonka, F. Courbin, G. Meylan +3
We have applied the MCS image deconvolution algorithm (Magain, Courbin & Sohy 1998) to HST/WFPC2 V, I data of three M31 bulge globular clusters (G170, G177, and G198) and control f…
