Companions of bright barred Shapley-Ames galaxies.


Abstract (from CDS):

Companion galaxy environment for a subset of 78 bright and nearby barred galaxies from the Shapley-Ames Catalog is presented. Among the spiral barred galaxies, there are Seyfert galaxies, galaxies with circumnuclear structures, galaxies not associated with any large-scale galaxy cloud structure, galaxies with peculiar disk morphology (crooked arms), and galaxies with normal disk morphology; the list includes all Hubble types. The companion galaxy list includes the number of companion galaxies within 20 diameters, their Hubble type, and projected separation distance. In addition, the companion environment was searched for four known active spiral galaxies, three of them are Seyfert galaxies, namely, NGC 1068, NGC 1097, and NGC 5548, and one is a starburst galaxy, M82. Among the results obtained, it is noted that the only spiral barred galaxy classified as Seyfert 1 in our list has no companions within a projected distance of 20 diameters; six out of 10 Seyfert 2 bar galaxies have no companions within 10 diameters, six out of 10 Seyfert 2 galaxies have one or more companions at projected separation distances between 10 and 20 diameters; six out of 12 galaxies with circumnuclear structures have two or more companions within 20 diameters.
