Search for Southern-Hemisphere Giant Radio Galaxies with SALT
J. Machalski, S Zola, D. Koziel +1
An extensive search for distant Giant radio galaxies on the southern hemisphere is justified. We emphasize the crucial role of optical spectroscopy in determination of their basic…
Redshift Measurements of Faint Distant Giant Radio Galaxies and Observational Constraints on their Jet Power and Dynamical Age
K. Chyzy, M. Jamrozy, S. J. Kleinman +6
The redshifts of faint radio galaxies identified with giant radio source candidates selected from the sample of Machalski et al. (2001) have been measured. Given the redshift, the…
Giant Radio Sources in View of the Dynamical Evolution of FRII-type Population
J. Machalski, K. Chyzy, M. Jamrozy
The time evolution of giant (D>1 Mpc) lobe-dominated galaxies is analysed on the basis of dynamical evolution of the entire FRII-type population.
Molecular Gas in the Galactic Center Region II. Gas mass and N(H_2)/I(^12CO) conversion based on a C^18O(J = 1 -> 0) Survey
G. Dahmen, S. Huettemeister, T. L. Wilson +1
The large scale structure and physics of molecular gas in the Galactic center region is discussed based on the analysis of a 9' resolution survey of the Galactic center region in t…
