The discovery of quasars
Although the extragalactic nature of quasars was discussed as early as 1960, it was rejected largely because of preconceived ideas about what appeared to be an un- realistically high radio and
The physical properties and cosmic environments of quasars in the first Gyr of the universe
Luminous quasars at redshift z &6, i.e. .1 Gyr after the Big Bang, are formidable probes of the early universe, at the edge of the Epoch of Reionization. These sources are predicted to be found in

Abstract Although the extragalactic nature of 3C 48 and other quasi stellar radio sources was discussed as early as 1960 by John Bolton and others, it was rejected largely because of preconceived
The Discovery of Quasars and its Aftermath
Although the extragalactic nature of quasars was discussed as early as 1960, it was rejected largely because of preconceived ideas about what appeared to be an unrealistically high radio and optical
Extended Emission-Line Regions: Remnants of Quasar Superwinds?
We give an overview of our recent integral-field-unit spectroscopy of luminous extended emission-line regions (EELRs) around low-redshift quasars, including new observations of five fields. Previous

Active Galactic Nuclei and Pulsars
With the discovery of radio emission of extraterrestrial origin, it had opened a new and broader window in the electromagnetic spectrum to observe the sky. Two of the common sources of radio

Construction d'un spectrographe et recherche de quasars pour le projet d'étude de l'énergie noire, DESI
L'acceleration de l'expansion de l'Univers est l'un des sujets majeurs de la cosmologie actuelle. Elle pourrait etre due a une nouvelle composante, appelee energie noire, qui representerait 70% du
