USS Sources

(A sample of 669 ultra steep spectrum radio sources to find high redshift radio galaxies)
(catalog of sources with steep spectral index)

I use the term USS Sources for the list of Radio sources in A sample of 669 ultra steep spectrum radio sources to find high redshift radio galaxies, a list with Spectral Indexes (α) < -1.3, suggesting a high Redshift (z). The catalog is collected from the surveys, Texas Survey of Radio Sources at 365 MHz (TXS), NRAO VLA Sky Survey (NVSS), Parkes-MIT-NRAO Surveys (PMN), WENSS (Westerbork Northern Sky Survey, by the Westerbork Synthesis Radio Telescope (WSRT))), MRC (Molonglo Reference Catalog), and FIRST (Faint Images of Radio Sky at Twenty centimeters).
