Clear evidence for the early triggering of a luminous quasar-like AGN in a major, gas rich merger
Patricia S. Bessiere, Clive N. Tadhunter, Cristina Ramos Almeida +1
We present deep, intermediate resolution, long slit Gemini GMOS-S optical spectra of the SDSS type II quasar J002531-104022, which is a highly disturbed system currently undergoing…
The environments of luminous radio galaxies and type-2 quasars
Cristina Ramos Almeida, P. S. Bessiere, C. Tadhunter +5
We present the results of a comparison between the environments of 1) a complete sample of 46 southern 2Jy radio galaxies at intermediate redshifts (0.05 < z < 0.7), 2) a complete…
The importance of galaxy interactions in triggering type II quasar activity
Patricia Bessiere, Clive N. Tadhunter, Cristina Ramos Almeida +1
We present deep Gemini GMOS-S optical broad-band images for a complete sample of 20 SDSS selected type II quasars with redshifts 0.3 < z < 0.41 and [OIII] emission line luminositie…
Mergers and interactions in SDSS type 2 quasars at z~0.3-0.4. SDSS J143027.66-005614.8: a case study
Montse Villar-Martin, Antonio Cabrera-Lavers, Patricia Bessiere +3
We present a compilation of HST images of 58 luminous SDSS type 2 AGNs at 0.3<z<0.4. 42 of them are type 2 quasars, which are a good representation of all optically selected SDSS t…
Are luminous radio-loud active galactic nuclei triggered by galaxy interactions?
C. Ramos Almeida, P. S. Bessiere, C. Tadhunter +6
We present the results of a comparison between the optical morphologies of a complete sample of 46 southern 2Jy radio galaxies at intermediate redshifts (0.05<z<0.7) and those of t…
