Extragalactic astronomy with the OHANA array
SPIE Proceedings, 2003The Optical Hawaiian Array for Nanoradian Astronomy (OHANA) will allow resolutions on the order of a fraction of a milliarcsecond in the near infrared. This corresponds to the suspected size of the Broad Line Region and might even allow to study the structure of the base of jets.

Extragalactic Soft X-ray Astronomy
Nature, 1968The opacity of the galaxy to soft X-rays may be less than previously supposed. This may permit a variety of extragalactic objects to be observed at ∼50 A. Some implications of this situation are discussed here.

Recent Results in Astronomy I: Extragalactic
1989One of the main aims of the extragalactic radioastronomy is to understand the physical phenomenon ”radiosource”, produced by high energy processes which take place mainly in the centres of galaxies and quasars. Typical radio structures of powerful radiosources lead to the acceptance of the idea of ordered collimated outflowing of matter from nuclei to ...

Space Science Reviews, 1983
Extragalactic γ-ray astronomy is in its infancy. In this paper a review is presented of the γ-ray emission of the few individual objects observed to date and some conclusions are drawn as to their possible general characteristics. A number of scenarios suitable for the generation of γ-rays are presented in the light of these recent measurements.

Extragalactic Astronomy with 2MASS
1998Observations for the Two-Micron All Sky Survey (2MASS) have recently begun at the northern hemisphere site. The project is now in the final phases of tuning the data analysis software in preparation for running the “pipeline” at full bore. The path to completing the extragalactic portion of the pipeline, called GALWORKS, was complicated. It required an
