Filaments in the Galactic Center -- with special reference to the Snake
G. V. Bicknell, J. K. Li
The nonthermal filaments in the Galactic Center constitute one of the great mysteries of this region of the Galaxy. We summarise the observational data on these filaments and criti…
A Proper Motion Survey for White Dwarfs with the Wide Field Planetary Camera 2
Cailin A. Nelson, Kem H. Cook, Tim S. Axelrod +2
We have performed a search for halo white dwarfs as high proper motion objects in a second epoch WFPC2 image of the Groth-Westphal strip. We identify 24 high proper motion objects…
An HI survey of the Centaurus and Sculptor Groups - Constraints on the space density of low mass galaxies
W. J. G. de Blok, M. A. Zwaan, M. Dijkstra +2
We present results of two 21-cm HI surveys performed with the Australia Telescope Compact Array in the nearby Centaurus A and Sculptor galaxy groups. These surveys are sensitive to…
The Fundamental Properties of Early-type Galaxies in the Coma Cluster
Stephen A. W. Moore, J. R. Lucey, H. Kuntschner +2
We report the results of a high quality spectral study of early-type galaxies within the Coma Cluster core. Stellar population analysis using Lick/IDS indices to break the age/meta…
Surface brightness fluctuation distances for nearby dwarf elliptical galaxies
Helmut Jerjen, Rami Rekola, Leo Takalo +2
We obtained B and R-band CCD images for the dwarf elliptical (dE) galaxies DDO44, UGC4998, KK98_77, DDO71, DDO113, and UGC7356 at the NOT. Using Fourier analysis technique we measu…
Variable Stars in the Fornax Dwarf Galaxy
D. Bersier, P. R. Wood
We present a search for variable stars in the Fornax dwarf galaxy covering an area of 1/2 a square degree. We have ~30 epochs of VI data. We found and determined periods for more t…
