The ruff of equatorial emission around the SS433 jets: its spectral index and origin
Proceedings of the 4th Microquasar Workshop (2003)
Abstract:
We present unique radio observations of SS433, using MERLIN, the VLBA, and the VLA, which allow us to, for the first time, properly image and derive a meaningful spectral index for the `ruff' of equatorial emission which surrounds SS433's jet. We interpret this smooth ruff as a wind-like outflow from the binary.The mass of radio galaxies from low to high redshift
ESO ASTROPHY SYMP (2003) 148-153
Abstract:
Using a new radio sample, 6C* designed to find radio galaxies at z > 4 along with the complete 3CRR and 6CE sample we extend the radio galaxy K - z relation to z similar to 4.5. The 6C* K - z data significantly improve delineation of the K - z relation for radio galaxies at high redshift (z > 2). In a spatially flat universe with a cosmological constant (Omega(M) = 0.3 and Omega(A) = 0.7), the most luminous radio sources appear to be associated with galaxies with a luminosity distribution with a high mean (approximate to 5L*), and a low dispersion (sigma similar to 0.5 mag) which formed their stars at epochs corresponding to z greater than or similar to 2.5).Near-infrared imaging and the K-z relation for radio galaxies in the 7C Redshift Survey
