Deep Optical Imaging of A Compact Group of Galaxies, Seyfert's Sextet
S. Nishiura, T. Murayama, M. Shimada +5
In order to investigate the dynamical status of Seyfert's Sextet (SS), we have obtained a deep optical () image of this group. Our image shows that a faint envelope, down to…
A Dynamical Study of Galaxies in the Hickson Compact Groups
S. Nishiura, M. Shimada, Y. Ohyama +2
In order to investigate dynamical properties of spiral galaxies in the Hickson compact groups (HCGs), we present rotation curves of 30 galaxies in 20 HCGs. We found as follows. 1)…
The Nuclear Activity of the Galaxies in the Hickson Compact Groups
Masashi Shimada, Youichi Ohyama, Shingo Nishiura +2
In order to investigate the nuclear activity of galaxies residing in compact groups of galaxies, we present results of our optical spectroscopic program made at Okayama Astrophysic…
Discovery of a Low Surface Brightness Object near Seyfert's Sextet
Takashi Murayama, Shingo Nishiura, Tohru Nagao +3
We report the discovery of a low surface brightness (LSB) object serendipitously found during deep CCD imaging of a compact group of galaxies, Seyfert's Sextet, in VR and I bands.…
