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 < -1.3,
suggesting a high redshift.
The catalog is collected from the surveys,
the Texas Survey of Radio Sources at 365 MHz (TXS),
the NRAO VLA Sky Survey (NVSS),
the Parkes-MIT-NRAO Surveys (PMN),
the Molonglo Reference Catalog (MRC),
the Faint Images of Radio Sky at Twenty centimeters (FIRST),
and WENSS (the Westerbork Northern Sky Survey, by the Westerbork Synthesis Radio Telescope (WSRT)),
(catalog,radio)
