Using SNAP for Galactic & extragalactic astronomy

Astrophysics and Space Science, 2007
SNAP, 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 ...

Extragalactic Radio Astronomy: Galaxy Classification, Active Galactic Nuclei, Superluminal Motion, Galaxy Clusters, and the Cosmic Microwave Background

2020
This chapter presents a summary of observations conducted at radio frequencies of extragalactic astronomical sources. An initial discussion is given on the general properties of galaxies, cosmology, and Hubble’s law. Radio observations of normal galaxies—both HI line and radio continuum—are examined, including an introduction to the Tully–Fisher ...

Some Quantitative Aspects of Galactic and Extragalactic Infrared Astronomy

2007
Two types of infrared astrophysical problems have been intensively studied in recent years. The first is an investigation of primary coolants. The second is the nature of the diffuse extragalactic infrared background radiation.
