Abstract

B and R CCD images have been obtained of the morphologically peculiar galaxy A1627 + 39, which lies near the center of the rich cluster of galaxies A2199. The galaxy is determined to be a nearly face-on barred S0 galaxy containing two nonconcentric rings. The rings are quite unusual in that they are displaced in opposite directions from the galactic center. There is no color difference across the rings, indicating no recent burst of star formation. Two hypotheses for the origin of the rings have been investigated: (1) a resonance effect with the central bar, and (2) the result of an off-axis, deeply penetrating collision with another cluster member. Models of such a collision are presented, which can reproduce the observed rings. However, neither hypothesis can provide a completely satisfactory explanation of all the observations reported here. 32 refs.

A Redshift Survey of the Nearby Galaxy Cluster Abell 2199: Comparison of the Spatial and Kinematic Distributions of Galaxies with the Intracluster Medium

Journal Article Song, Hyunmi; Hwang, Ho; Park, Changbom; ... - Astrophysical Journal

We present the results from an extensive spectroscopic survey of the central region of the nearby galaxy cluster Abell 2199 (A2199) at z = 0.03. By combining 775 new redshifts from the MMT/Hectospec observations with the data in the literature, we construct a large sample of 1624 galaxies with measured redshifts at R<30{sup ′}, which results in high spectroscopic completeness at r{sub petro,0}<20.5 (77%). We use these data to study the kinematics and clustering of galaxies, focusing on the comparison with those of the intracluster medium (ICM) from Suzaku X-ray observations. We identify 406 member galaxies of A2199 at R<30{sup ′} usingmore »« less

Weakly barred early-type ringed galaxies. III. The remarkable outer-ringed S0+ galaxy NGC 7020

Journal Article Buta, R - Astrophysical Journal; (USA)

The southern S0+ galaxy NGC 7020 presents an unusual morphology: it includes a very regular outer ring which is completely detached and which envelops an inner ring/lens zone with an exotic hexagonal shape. The ring has a high contrast compared with those usually observed in barred galaxies, yet NGC 7020 is not obviously barred. In this paper, the structure of this galaxy is studied by means of UBVRI CCD surface photometry. The photometry reveals a complex system and shows that most of the recent star formation in the galaxy has taken place in the outer ring. Two bright knots aremore »« less

Weakly barred early-type ringed galaxies. IV. The double-ringed SO(+) galaxy NGC 7702

Journal Article Buta, R - Astrophysical Journal; (USA)

UBVRI surface photometry of NGC 7702, obtained with a CCD detector on the 3.9-m Anglo-Australian Telescope and with photographic plates on the 4-m telescope at CTIO, is reported. The data are presented in tables, graphs, and contour maps and characterized in detail. NGC 7702 is found to be a true S0(+) galaxy with a bright high-contrast inner ring and a faint low-contrast outer ring; the inner ring is significantly elongated relative to typical SB inner rings and has colors which suggest a burst of star formation less than 2 Gyr ago. A small oval revealed by the bulge isophotes inmore »« less

Weakly barred early-type ringed galaxies. II. The double-ringed S0(+) galaxy NGC 7187

Journal Article Buta, R - Astrophysical Journal; (USA)

CCD surface photometry of the southern ringed S0(+) galaxy NGC 7187, a particularly good example of a system with two bright clear rings with significantly different apparent shapes and almost no sign of a bar, is presented. The galaxy has below average luminosity and the rings are small compared to those observed in more typical (R)SB(r) type galaxies, even though the ratio of their sizes is similar to those in such galaxies. Bulge isophotes reveal the existence of two nearly orthogonal ovals, one having the same shape and position angle as isophotes of the outer disk. The central oval showsmore »« less

Weakly barred, early-type ringed galaxies. I. The Seyfert galaxy NGC 3081

Journal Article Buta, R - Astrophysical Journal; (USA)

Four extreme examples illustrate the diverging characteristics of bright galactic rings. The galaxies are studied by means of multicolor CCD surface photometry. The ringed Seyfert galaxy NGC 3081 is an S0/a system possessing an unusually high contrast inner ring enveloping a weak bar. The structure of this galaxy is described using BVR(C)I(C) surface photometry. The observations reveal a complex system which shares many properties in common with NGC 1433, a prototype SB(r) type spiral with a strong bar. Significant azimuthal variations in the color indices occur around the ring which are probably due to the elongated shape. It is suggestedmore »« less
