Compact High-Velocity Clouds at High Resolution
W. B. Burton, Robert Braun
Six examples of the compact, isolated high-velocity clouds catalogued by Braun & Burton (1999) and identified with a dynamically cold ensemble of primitive objects falling towards…
Population of the Scattered Kuiper Belt
C. A. Trujillo, D. C. Jewitt, J. X. Luu
We present the discovery of three new Scattered Kuiper Belt Objects (SKBOs) from a wide-field survey of the ecliptic. This continuing survey has to date covered 20.2 square degrees…
More redshifts of powerful equatorial radio sources from the BRL sample
P. N. Best, H. J. A. R"ottgering, M. D. Lehnert
A new sample of very powerful radio sources, defined from the Molonglo Reference Catalogue, was recently compiled by Best, Rottgering and Lehnert (1999). These authors provided red…
Multicolour Optical Imaging of IR-Warm Seyfert Galaxies. V. Morphologies and Interactions. Challenging the Orientation Model
Eleni T. Chatzichristou
This paper is the last in a series, investigating the optical properties of a sample of mid-IR Warm Seyfert galaxies and of a control sample of mid-IR cold galaxies. In the present…
Probing a regular orbit with spectral dynamics
Y. Copin, H. S. Zhao, P. T. de Zeeuw
We have extended the spectral dynamics formalism introduced by Binney & Spergel, and have implemented a semi-analytic method to represent regular orbits in any potential, making fu…
Multicolour Optical Imaging of IR-Warm Seyfert Galaxies. II. Optical and IR Properties and their Correlations
Eleni T. Chatzichristou
This paper is the second in a series, studying the optical properties of a sample of mid-IR Warm Seyfert galaxies and a control sample of mid-IR Cold galaxies. The present paper is…
