Trigonometric parallaxes of high velocity halo white dwarf candidates
C. Ducourant, R. Teixeira, N. C. Hambly +5
The status of 38 halo white dwarf candidates identified by Oppenheimer et al. (2001) has been intensively discussed by various authors. In analyses undertaken to date, trigonometri…
Discovery of distant high luminosity infrared galaxies
Paul P. van der Werf, D. L. Clements, P. A. Shaver +1
We have developed a method for selecting the most luminous galaxies detected by IRAS based on their extreme values of R, the ratio of 60 micron and B-band luminosity. These objects…
Dark galaxies, spin bias and gravitational lenses
Raul Jimenez, A. F. Heavens, M. R. S. Hawkins +1
Gravitational lensing studies suggest that the Universe may contain a population of dark galaxies; we investigate this intriguing possibility and propose a mechanism to explain the…
The Double Quasar Q2138-431: Lensing by a Dark Galaxy?
M. R. S. Hawkins, D. Clements, J. W. Fried +4
We report the discovery of a new gravitational lens candidate Q2138-431AB, comprising two quasar images at a redshift of 1.641 separated by 4.5 arcsecs. The spectra of the two imag…
