A spectroscopic study of NGC 6251 and its companion galaxies
Measurements of the velocities of galaxies thought to be associated with the giant radio galaxy NGC 6251 confirm the presence of a poor cluster with a systemic redshift of z = 0.0244 ± 0.0004 and a line-of-sight velocity dispersion of σ z = 283 (+109, −52) km s −1. This suggests a cluster atmosphere temperature of T = 0.7 (+0.6, −0.2) keV, which is not enough to confine the radio jet by gas pre...
متن کاملStudy of the NGC 6744 System Stuart
We present the preliminary results of our 5-configuration, 20-pointing mosaic with the Australia Telescope Compact Array of the neutral hydrogen in the nearby spiral galaxy NGC 6744. The bulk of the HI resides in a ‘ring’ underlying the outer optical disk, with 2 HI spiral arms extending further out to almost 1 ·5 optical radii. The velocity field is fairly regular, apart from evidence for stre...
متن کاملThe star - burst galaxies NGC 278 , NGC 660 , NGC 3628 , NGC 4631 , and NGC 4666
Aims. We study the physical properties and mass of molecular gas in the central regions of galaxies with active nuclei. GHz [CI] maps in three of these are used to model the molecular gas. Results. All five objects contain bright CO emission in the central regions. Clear central concentrations were found in NGC 660, NGC 3628, and NGC 4666, but not in the weakest CO emitters NGC 278 and NGC 4631...
متن کاملSpectroscopic Evidence for a Supermassive Black Hole in Ngc 4486b
The stellar kinematics of the low-luminosity elliptical galaxy NGC 4486B have been measured in seeing σ∗ = 0. 22 with the Canada-France-Hawaii Telescope (CFHT) and Subarcsecond Imaging Spectrograph. Lauer and collaborators have shown that NGC 4486B is similar to M31 in having a double nucleus. Here we show that it also resembles M31 in its kinematics. Like M31, NGC 4486B rotates fairly rapidly ...
متن کاملSpectroscopic Abundances in Cool Pleiades Dwarfs and Ngc 2264 Stars
We derive parameters and abundances of several elements in two cool Pleiades dwarfs, four cool NGC 2264 preÈmain-sequence stars, and a probable NGC 2264 nonmember from high-resolution, moderate signal-to-noise ratio, Keck/HIRES spectra. Our Pleiades Fe abundance agrees with previous spectroscopic and photometric values of hotter stars and does not resolve the 0.3 mag distance modulus discrepanc...
