The Influence of Horizontal Boundaries on Ekman Circulation and Angular Momentum Transport in a Cylindrical Annulus
Aleksandr V. Obabko, Fausto Cattaneo, Paul F. Fischer
We present numerical simulations of circular Couette flow in axisymmetric and fully three-dimensional geometry of a cylindrical annulus inspired by Princeton MRI liquid gallium exp…
Obscured and Unobscured AGN Evolution and the X-ray background
Ezequiel Treister, C. Megan Urry, Paulina Lira
The Great Observatories Origins Deep Survey (GOODS) combines deep HST and Spitzer imaging with the deepest Chandra/XMM observations to probe obscured AGN at higher redshifts than p…
Timing and spectral studies of the transient X-ray pulsar EXO 053109-6609.2 with ASCA and Beppo-SAX
B. Paul, S. N. A. Jaaffery, S. Naik +1
We report timing and spectral properties of the transient Be X-ray pulsar EXO 053109--6609.2 studied using observations made with the ASCA and BeppoSAX observatories. Though there…
Measurement of the Hubble Constant Via Gravitational Lensing--- A Review of the Jodrell Bank ``Golden Lenses'' Workshop
Liliya L. R. Williams, Paul L. Schechter
Gravitational lensing is now widely and successfully used to study a range of astronomical phenomena, from individual objects, like galaxies and clusters, to the mass distribution…
