The 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 کاملPhotometric Survey of the Polar Ring Galaxy Ngc 6822
We have previously established, from a carbon star survey, that the Local Group dwarf irregular galaxy NGC 6822 is much larger than its central bright core.
متن کاملKinematic modeling of disk galaxies III . The warped “ Spindle ” NGC 2685
This is the third of a series of papers in which the structure and kinematics of disk galaxies is studied. Employing direct tilted-ring fits to the data cube as introduced in Paper I, we perform an analysis of the " Spindle " galaxy NGC 2685, previously regarded as two-ringed polar ring galaxy. Deep H i and optical (i ′-band) observations are presented. The H i observations strongly suggest tha...
متن کاملA Local Group Polar Ring Galaxy : NGC 6822
Star counts, obtained from a 2 × 2 degree area centered on NGC 6822 have revealed an optical image of this galaxy composed of two components: in addition to the well-known HI disk with its young stellar component, there is a spheroidal stellar structure as extensive as its HI disk but with its major axis at roughly right angles to it which we traced to at least 9 scale lengths. Radial velocitie...
متن کاملRadio spectral index images of the spiral galaxies NGC 0628 , NGC 3627 , and NGC 7331
Aims. In order to understand the cosmic ray propagation mechanism in galaxies, and its correlation with the sites of star formation, we compare the spatially resolved radio spectral index of three spiral galaxies with their IR distribution. Methods. We present new low-frequency radio continuum observations of the galaxies NGC 0628, NGC 3627, and NGC 7331, taken at 327 MHz with the Very Large Ar...
