Towards the Event Horizon - The Vicinity of AGN at Micro-Arcsecond Resolution
T. P. Krichbaum, D. A. Graham, W. Alef +18
We summarize the present status of VLBI experiments at 3 mm (86 GHz), 2 mm (129-150 GHz) and 1.3 mm (215-230 GHz). We present and discuss a new 3 mm VLBI map of M87 (Virgo A), whic…
The cluster environments of radio loud quasars
J. M. Barr, M. N. Bremer, J. C. Baker +1
We have carried out multi-colour imaging of the fields of a statistically complete sample of low-frequency selected radio loud quasars at 0.6<z<1.1, in order to determine the chara…
The environments of radio-loud quasars
J. M. Barr, M. N. Bremer, J. C. Baker
We have obtained multi-colour imaging of a representative, statistically complete sample of low-frequency selected (S_408MHz > 0.95Jy) radio loud quasars at intermediate (0.6 < z <…
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…
