An old galaxy group : Chandra X - ray observations of the nearby fossil group NGC 6482
We present the first detailed X-ray observations, using Chandra , of NGC 6482 – the nearest known ‘fossil group’. The group is dominated by an optically luminous giant elliptical galaxy and all other known group members are at least two magnitudes fainter. The global X-ray properties (luminosity, temperature, extent) of NGC 6482 fall within the range of other groups, but the detailed properties...
متن کاملHerschel-SPIRE observations of the disturbed galaxy NGC 4438*
We present Herschel-SPIRE observations of the perturbed galaxy NGC 4438 in the Virgo cluster. These images reveal the presence of extra-planar dust up to ∼4–5 kpc away from the galaxy’s disk. The dust closely follows the distribution of the stripped atomic and molecular hydrogen, supporting the idea that gas and dust are perturbed in a similar fashion by the cluster environment. Interestingly, ...
متن کاملThe Isolated Elliptical Ngc 1132: Evidence for a Merged Group of Galaxies?
Numerical simulations predict that some poor groups of galaxies have merged by the present epoch into giant ellipticals (cf. Barnes 1989). To identify the possible remnants of such mergers, we have compiled a sample of nearby, isolated ellipticals (Colbert, Mulchaey, & Zabludoff 1998). ASCA observations of the first galaxy studied, NGC 1132, reveal an X-ray halo that extends out to at least ≈ 2...
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 کاملGas Sloshing and Bubbles in the Galaxy Group Ngc 5098
We present results from Chandra observations of the galaxy pair and associated galaxy group NGC 5098, and find evidence for both gas sloshing and AGN heating. The X-ray brightness images show diffuse emission with a spiral structure, centered on NGC 5098a, and a sharp edge in the diffuse emission surrounding much of the galaxy at about 30 kpc. The spiral structure in the X-ray surface brightnes...
