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.
On the time evolution of giant radio galaxies
J. Machalski, K. T. Chyzy, M. Jamrozy
A time evolution of giant lobe-dominated radio galaxies (with projected linear size Mpc) is analysed on the basis of dynamical evolution of the entire FRII-type population. T…
Regular magnetic fields in the dwarf irregular galaxy NGC 4449
K. T. Chyzy, R. Beck, S. Kohle +2
We present a high-resolution VLA study of the total power and polarized radio continuum emission at 8.46 and 4.86 GHz of the irregular galaxy NGC 4449, known for its weak rotation…
