The discovery of quasars
- Physics
- 2013
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
- Physics
- 2018
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…

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?
- Physics
- 2008
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…

Les systemes Lorentziens Lyman-alpha a grand decalage spectral, observes en absorption sur la ligne de visee de quasars, sont les signatures spectrales du milieu interstellaire dans l'Univers…
Active Galactic Nuclei and Pulsars
- Physics
- 2020
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…
