A 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 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 کاملDust and molecules in the Local Group galaxy NGC 6822
Emission from the J=1-0 12 CO transition was detected unambiguously at 4 out of 17 observed positions in the Magellanic irregular galaxy NGC 6822; two more positions yielded marginal 3σ detections. These positions include the HII region complexes Hubble V and Hubble I/III, and two IRAS far-infrared emission peaks not associated with bright HII regions. The bright HII region Hubble X was not det...
متن کاملIonized Gas inside the dwarf irregular galaxy NGC 6822 1
We have studied the differences between the diffuse ionized gas (DIG) and the H ii regions along a slit position in the local dwarf irregular galaxy NGC 6822. The slit position passes through the two most prominent H ii regions: Hubble V and Hubble X. Important differences have been found in the excitation, ionization, and [N ii]λ6584Å/Hα and [S ii]λ6717Å/Hα line ratios between the DIG and the ...
متن کاملDust and molecules in the Local Group galaxy NGC 6822 III . The first - ranked HII region complex Hubble
We present maps of the first-ranked HII region complex Hubble V in the metal-poor Local Group dwarf galaxy NGC 6822 in the first four transitions of CO, the 158μm transition of C, the 21-cm line of HI, the Paβ line of HII, and the continuum at 21 cm and 2.2 μm wavelengths. We have also determined various integrated intensities, notably of HCO and near-IR H2 emission. Although Hubble X is locate...
