Search for Nemesis Encounters with Vega, epsilon Eridani, and Fomalhaut
J. -M. Deltorn, P. Kalas
We calculate the space motions of 21,497 stars to search for close stellar encounters with Vega, epsilon Eridani and Fomalhaut during the past 1 Myr. We discover that epsilon Erida…
Stellar Encounters with the Beta Pictoris Planetesimal System
Paul Kalas, Jean-Marc Deltorn, John Larwood
We use data from the Hipparcos Catalog and the Barbier-Brossat & Figon (2000) catalog of stellar radial velocities to test the hypothesis that the Beta Pic planetesimal disk was di…
A Massive Cluster of Galaxies at z = 0.996
J. -M. Deltorn, O. Le Fevre, David Crampton +1
We report the identification of a cluster of galaxies around the high-redshift radio galaxy 3CR184 at z = 0.996. The identification is supported by an excess of galaxies observed i…
Clustering around the radio-galaxy MRC0316-257 at z=3.14
O. Le Fevre, J. M. Deltorn, D. Crampton +1
We report here the spectroscopic identification of galaxies in the neighborhood of the radio-galaxy MRC0316-257, at a redshift . Candidate cluster galaxies were selected…
