A dwarf galaxy with a giant HI disk
We present Giant Meterwave Radio Telescope (GMRT) HI 21cm images of a nearby dwarf irregular galaxy NGC 3741 (MB ∼ −13.13) which show it to have a gas disk that extends to ∼ 8.3 times its Holmberg radius. This makes it probably the most extended gas disk known. Our observations allow us to derive the rotation curve (which is flat in the outer regions) out to ∼38 optical scale lengths. NGC 3741 ...
متن کاملThe Shape and Figure Rotation of NGC 2915 ’ s Dark Halo
NGC 2915 is a blue compact dwarf galaxy with a very extended H I disk. This disk shows a short central bar and extended spiral arms, both reaching far beyond the optical component. We use Tremaine & Weinberg's (1984) method to measure the pattern speed of the bar and spiral arms from H I radio synthesis data. Our measurements yield a pattern speed of Ω p = 0.21 ± 0.06 km s −1 arcsec −1 (8.0 ± 2...
متن کاملUnified Rotation Curve of the Galaxy — Decomposition into de Vaucouleurs Bulge , Disk , Dark Halo , and the 9 - kpc Rotation Dip —
We present a unified rotation curve of the Galaxy re-constructed from the existing data by re-calculating the distances and velocities for a set of galactic constants R0 =8 kpc and V0 =200 km s . We decompose it into a bulge with de Vaucouleurs-law profile of half-mass scale radius 0.5 kpc and mass 1.8×10M⊙, an exponential disk of scale radius 3.5 kpc of 6.5× 10M⊙, and an isothermal dark halo o...
متن کاملPseudo Rotation Curve connecting the Galaxy , Dark Halo , and Local Group
We construct a Galacto-Local Group rotation curve, combining the Galactic rotation curve with a diagram, where galacto-centric radial velocities of outer globular clusters and member galaxies of the Local Group are plotted against their galacto-centric distances. The high-velocity ends of this pseudo rotation curve within a radius R ∼ 150 kpc are well traced by a rotation curve calculated for t...
متن کاملArcs from a Universal Dark-Matter Halo Profile
Navarro, Frenk, & White have recently found numerically that the density profile of dark-matter halos can be described by a universal two-parameter function over a broad range of halo masses. The profile is singular, approaching the halo center with ρ ∝ r−1. It had been argued previously that radially distorted, gravitationally lensed images of background sources in galaxy clusters, so-called r...
