LETTER: The Life and Times of Extremal Black Holes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-11)
Charged extremal black holes cannot fully evaporate through the Hawking effect and are thus long lived. Over their lifetimes, these black holes take part in a variety of astrophysical processes, including many that lead ...
Astronomical Engineering: A Strategy For Modifying Planetary Orbits
(Kluwer Academic Publishers; Springer Science+Business Media, 2001-03)
The Sun's gradual brightening will seriously compromise the Earth'sbiosphere within ∼ 10 9 years. If Earth's orbit migrates outward,however, the biosphere could remain intact over the entiremain-sequence lifetime of the ...
Protostellar Disk Formation and Early Evolution
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-03)
This contribution describes the formation of circumstellar disks and their earliest evolutionary phases when self-gravity in the disk plays a crucial role in eliciting the transport of mass and angular momentum. We first ...
The asymptotic form of cosmic structure: Small-scale power and accretion history
(Univ Chicago Press, 2007-08-10)
We explore the effects of small-scale structure on the formation and equilibrium of dark matter halos in a universe dominated by vacuum energy. We present the results of a suite of four N-body simulations, two with a Lambda ...
The ultimate halo mass in a ?CDM universe
(Blackwell Science Ltd, 2004-10-01)
In the far future of an accelerating ?CDM cosmology, the cosmic web of large-scale structure consists of a set of increasingly isolated haloes in dynamical equilibrium. We examine the approach of collisionless dark matter ...
The asymptotic structure of space-time
(World Scientific Publ Co Pte Ltd, 2003-10)
Astronomical observations strongly suggest that our universe is now accelerating and contains a substantial admixture of dark vacuum energy. Using numerical simulations to study this newly consolidated cosmological model ...
Future evolution of cosmic structure in an accelerating universe
(Univ Chicago Press, 2003-10-20)
Current cosmological data indicate that our universe contains a substantial component of dark vacuum energy that is driving the cosmos to accelerate. We examine the immediate and longer term consequences of this dark energy ...
