Abstract:
Despite their importance for astrometry and navigation, the active
galactic nuclei (AGNs) that comprise the International Celestial
Reference Frame (ICRF) are relatively poorly understood, with key
information such as their spectroscopic redshifts, AGN spectral type,
and emission-/absorption-line properties generally missing from the
literature. Using an updated, publicly available, state-of-the-art
spectroscopic fitting code optimized for the spectra of AGNs from low
to high redshift, we present a catalog of emission-line and spectral
continuum parameters for 1014 unique ICRF3 objects with single-fiber
spectra from the Sloan Digital Sky Survey DR16. We additionally
present black hole virial mass scaling relationships that use
Hα-, Hβ-, MgII-, and CIV-based line widths, all consistent
with each other, which can be used in studies of radio-loud objects
across a wide range of redshifts, and we use these scaling
relationships to provide derived properties such as black hole masses
and bolometric luminosities for the catalog. We briefly comment on
these properties for the ICRF objects, as well as their overall
spectroscopic characteristics.
Description:
Optical spectra for ICRF3 sources (Charlot+, 2020, J/A+A/644/A159)
were obtained from the SDSS DR16 (see V/154).

Note (1): Of the 1014 unique ICRF3 sources, 58 (5.7%) are defining sources
("True"), and the remaining 956 objects (94.3%) are densifying sources.
See Section 2.
Note (2): AGN type as follows:
QSO = quasars; 602 occurrences
Sy 1 = Seyfert 1; 198 occurrences
Sy 2 = Seyfert 2; 92 occurrences
featureless = no visible emission- or absorption-line features;
122 occurrences (see Section 2).
