"The entire Kazarian galaxies (KG) catalog is presented, which
combines extensive new measurements of their optical parameters with a
literature and database search. The measurements were made using images
extracted from the STScI Digitized Sky Survey (DSS) of J(pg)(blue),
F-pg(red), and I-pg(NIR) band photographic sky survey plates obtained
by the Palomar and UK Schmidt telescopes," scientists in Yerevan,
Armenia report.
"We provide accurate coordinates, morphological types, spectral and
activity classes, blue apparent diameters, axial ratios, position
angles, red, blue, and NIR apparent magnitudes, as well as counts of
neighboring objects in a circle of radius 50 kpc from centers of KG.
Special attention was paid to the individual descriptions of the
galaxies in the original Kazarian lists, which clarified many cases
of misidentifications of the objects, particularly among interacting
systems. The total number of individual Kazarian objects in the
database is now 706. We also include the redshifts, which are now
available for 404 galaxies and the 2MASS infrared magnitudes for
598 KG. The database also includes extensive notes, which summarize
information about the membership of Kazarian galaxies in different
systems of galaxies and about revised activity classes and redshifts,"
wrote M.A. Kazarian and colleagues, Yerevan State University.
The researchers concluded: "An atlas of several interesting subclasses
of Kazarian galaxies is also presented."
Kazarian and colleagues published their study in Astrophysics (A
catalog of Kazarian galaxies. Astrophysics, 2010;53(1):57-69).
