The Angular Momentum of Magnetized Molecular Cloud Cores: A Two-Dimensional-Three-Dimensional Comparison
(Institute of Physics Publishing, Inc., 2010)In this work, we present a detailed study of the rotational properties of magnetized and self-gravitating dense molecular cloud cores formed in a set of two very high resolution three-dimensional molecular cloud simulations ... -
Asymptotic Symmetries and Charges in De Sitter Space
(Institute of Physics Publishing, 2011)The asymptotic symmetry group (ASG) at future null infinity \((I^+)\) of four-dimensional de Sitter spacetimes is defined and shown to be given by the group of three-dimensional diffeomorphisms acting on \(I^+\). Finite ... -
Candidates for Inelastic Dark Matter
(Springer, 2009)Although we have yet to determine whether the DAMA data represents a true discovery of new physics, among such interpretations inelastic dark matter (IDM) can match the energy spectrum of DAMA very well while not contradicting ... -
The Dynamics of Dense Cores in the Perseus Molecular Cloud II: the Relationship between Dense Cores and the Cloud
(Institute of Physics Publishing, Inc., 2010)We utilize the extensive datasets available for the Perseus molecular cloud to analyze the relationship between the kinematics of small-scale dense cores and the larger structures in which they are embedded. The kinematic ... -
Extremal Limits and Black Hole Entropy
(Springer, 2009)Taking the extremal limit of a non-extremal Reissner-Nordstrom black hole (by externally varying the mass or charge), the region between the inner and outer event horizons experiences an interesting fate--while this region ...
