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

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.

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 astronomy. Book 2. Galaxies: multiwavelength properties
2023This textbook follows the «Extragalactic Astronomy. Book 1. Galaxies: basic physical properties». Book 2 describes methods and instrumental means for obtaining and processing data on physical properties of galaxies in various spectral ranges. Attention is paid to galaxies with excess radiation in the IR, radio, UV, and X- bands, to the dwarf galaxies ...

Extragalactic X-Ray Astronomy from SAS–3
Japanese Journal of Applied Physics, 1978We discuss the variety of extragalactic X-ray sources and their emission mechanisms. A brief summary of X-ray data obtained with the rotating modulation collimator on SAS–3 together with radio/IR/visible spectral data is also presented.

Using SNAP for Galactic & extragalactic astronomy
Astrophysics and Space Science, 2007SNAP, the SuperNova Acceleration Probe, is planned as a space-based telescope designed specifically to search for and monitor cosmological supernovae and weak lensing. In this paper we propose some other mission objectives which are of great importance in the fields of Galactic and extragalactic astronomy and which can be done as by-products with the ...

Symmetries in Stellar, Galactic and Extragalactic Astronomy
2022Examples are presented for appearance of geometric symmetry in the shape of various astronomical objects and phenomena. Usage of these symmetries in astrophysical and extragalactic research is also discussed.

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 ...
